NATIONAL OILWELL VARCO’S 61ST ANNUAL RIG CENSUS
Global rig fleet grows, both onshore and offshore
CENSUS HIGHLIGHTS
Key statistics from the 2014 census include the following:
• The U.S. fleet had an overall increase of 199 rigs, pushing the total available count up about 7% to 3,254. This
net increase is the result of 387 rig additions and 188 rig
deletions, Fig. 1.
• The number of U.S. rigs counted as newly manufactured
rose in 2014, totaling 187 units.
• The number of rigs that were retired or removed from
service this year was 177, a slight decrease.
• U.S. rigs meeting the census definition of “active” rose to
2,269, up about 10%.
• Utilization of the U.S. fleet (combined land and offshore) grew three percentage points and now stands at
70%, Fig. 2.
• There were 319 U.S. rig owners counted in 2014, compared with 313 last year.

United States rig owners continued adding to their fleets in
2014 and were able to put more rigs to work. According to the
61st Annual NOV Rig Census, the U.S. available fleet made a
significant jump over the past year, and activity levels seemed
to support this increase.
When rig counts were tallied for the census in the early summer of 2014, commodity prices were strong enough to fuel additional drilling momentum. The gap between available and
active rigs shrank, and showed an overall strengthening in the
U.S. market. The Canadian drilling environment also showed
growth in availability, as newbuilds and reactivations were
added to the fleet. Canada experienced a turnaround in activity
levels, regaining most of the losses seen over the past two years.
Worldwide statistics were also encouraging for 2014. The
global offshore mobile fleet continued to make notable gains
in the number of available rigs added to the fleet. Again this
year, a large number of newly manufactured units came online,
with most having standing contracts to drill. Activity levels
rose, as well, and kept pace with available units, causing utilization for the offshore mobile fleet to be relatively unchanged.
With the exception of Asia (including China), international
utilization of rigs rose in most primary areas.

Note: 2002 data are estimates.
• Drilling contractors own 85% of all U.S. drilling rigs, a one
percentage point decrease this year, with operators owning the remaining 15%.
• The Canadian available rig fleet rose to 796 units, up 2%
from last year.
• Canadian rig activity jumped 22%, with active units numbering 352 in 2014.
• Utilization for Canada rebounded to 44%, compared with
37% last year.
• The global offshore mobile fleet’s available count grew 5%
this year, coming in at 890 units.
• The active count for the global offshore mobile fleet grew
4%, and reached 725.
• Utilization of the global offshore mobile fleet is now 81%,
just slightly lower than 2013’s level.
• All international regions, with the exception of Asia (including China), showed increases in rig utilization over
the past year.
• Every U.S. region had increases in available rigs, with the
exception of the Gulf Coast, which was essentially flat.
• Drilling contractors own 85% of the 2014 fleet, while operators own 15%.

*2004 adjustment made in conjuction with RigData
Every year, some rigs are considered “unavailable,” based
on census rules, and are “retired” from the U.S. fleet. Older
rigs with outdated equipment and technology, which have
been sitting idle for three or more years, are no longer considered available. Units that need a significant capital expenditure, or a considerable time investment, are also not counted
in the census.
Accidents that damage rigs beyond repair also put rigs out
of commission. When units are transferred to other countries
for more profitable ventures, these rigs are taken out of the
U.S. census and counted in other international tallies. Each of
these cases is counted as a reduction to the U.S. fleet. Total deletions this year numbered 188 rigs, a 9% drop since last year’s
207-unit decline. This was the lowest number of rig deletions
since 2008, Table 1.
The largest number of rigs deleted continues to be in
the “Removed from Service” category. This has remained
stable over the past year, with a net drop of just five units, to
177. This is quite a different story from the reduction seen
in 2013, when the number declined by about 50%. This
category includes any units that require a large capital expenditure, rigs auctioned for parts or cannibalized to keep
other rigs running, or units that have been stacked for three
or more years.
Note that some of these rigs may re-enter the census at a
later date, if drilling conditions warrant, but have to be disqualified presently, to ensure an accurate representation of the
current available fleet. If any of these rigs are re-introduced
to the fleet, they are typically categorized under the “Brought
Back Into Service” portion of the census, in the “Additions”
part of this article. There is always a need for some units to be
refurbished or reactivated, if economic conditions improve.
Depending on worldwide market conditions, companies
move their rigs into, and out of, the U.S., and we attempt to
follow these rig movements on a year-to-year basis. In this
year’s count, just six rigs moved out of the U.S., quite a few
less than the 22 units that were exported in 2013. These units
are classified in the “Moved out of the Country” category. Rig
movement into the U.S. is covered in the section below.

put some units in the final deletions category as “Destroyed.”
Five rigs were reported to have sustained significant harm in the
2014 census and were classified in this category. Specific information was not provided for all of them, but at least two rigs
were known to have burned, due to blowouts. This compares
to three rigs that were counted as destroyed in the 2013 census.
U.S. RIG ADDITIONS SWELL
After rig building slowed in 2013, rig expansion programs
accelerated in 2014, producing a significant number of new
units. Refurbishments were also extremely prolific this year.
As market conditions have improved, reactivations have been
a cost-effective way to bring units online quickly. Several rigs
were also brought into the U.S. from other countries. Census
figures show that 387 rigs were added to the fleet over the last
year, up 51% from the previous year. These additions considerably outnumbered the 188 deletions to the fleet, Table 1.
United States newbuilds rose in 2014 after having experienced a downturn in 2013. There still appear to be a plentiful supply of innovative rigs being produced, bringing down
the average fleet age. Over the past decade, 1,927 brand-new
units have been introduced into the U.S. fleet, indicating that
more than 60% are performing at a higher level of cost and efficiency. Of those new units, 187 were added during this year’s
census, compared with 147 added in 2013.

Subtotal, deletions
The number of U.S. rigs that were “Brought Back into Service” spiked in 2014. This year’s number came in at 193, more
than double the 97 units reactivated in 2013. Each of the rigs
that were reintroduced had been counted previously in a prior
census, but had been out of commission. Many of these 193
reactivations have been refurbished and are being counted
again as part of the U.S. available fleet.
Six rigs that “Moved into the Country” during the past year
are also counted in the census. This is down from the nine rigs
that moved into the U.S. during 2013. With six units moving in and six moving out, the net import/export count was
stable. In recent years, more rigs typically have moved out of
the U.S. than moved in, so it’s noteworthy that this was not the
case in 2014. Differences in rig movements are often minor, so
it can be difficult to tell when trends are reversing. However,
strict U.S. drilling regulations have been burdensome, and
rig owners have been drawn, justifiably, to other markets for
many years.
Lastly, just one rig “Assembled from Parts” was added to
the fleet in 2014. Although there are probably more units that
could be classified in this category, it is becoming increasingly
difficult to quantify, based on the data that are gathered. It
also can be hard to differentiate between refurbishments and
new assemblies, especially when rigs have changed ownership
and are renamed. For these reasons, beginning in 2015, the
“Assembled from Parts” category will be absorbed into the
“Brought Back into Service” category.
Total rig additions numbered 387, while deletions totaled
188 units. The net change in the fleet over the past year was
a 199-unit gain, up about 7%. This is compared with a fleet
increase of just 2% in 2013, Fig. 3.
CANADIAN FLEET REBOUNDS
The Canadian available fleet has made another significant
gain in rigs during 2014. This is the second year of increase
after several years of declining counts. Rigs retired from service matched fairly closely in number to those reactivated,
but newly manufactured rigs helped gains overcome losses to
achieve a further increase.
Rigs “Removed from Service” continues to be the primary cause of Canadian fleet attrition. This includes rigs
idle for greater than three years, or those requiring a large
4NOVEMBER 2014/WorldOil.com
capital outlay. Data gathered about these units indicated that
38 fell into this category and were, therefore, dropped from
the census available count. This is less than the 52 rigs removed in 2013. Eleven rigs also were taken out of the census in 2014, due to being “Moved out of the Country.” This
was a noteworthy decline, compared with the 21 rigs that
were relocated last year. Most of these rigs were headed to
the U.S. market, but several were bound for Latin America. No Canadian units were reported as “Destroyed” over
the past year. The sum of all deletions totaled 49 units
in 2014.
The number of “Newly Manufactured” rigs entering the
Canadian fleet has declined this year after a resurgence in
2013. For 2014, the number of brand-new rigs totaled 24. This
was a decrease from the 64 units that were built from scratch
in 2013. Rigs “Brought Back into Service” have been stable
for the past five years, with 32 being the number reactivated
for 2014. Rigs “Moved into the Country” for Canada doubled
over the past year, as 12 were counted as being imported. This
makes a net addition of one rig, when looking at the import/
export balance. No units were indicated as “Assembled from
Parts.” Total rig additions came to 68 units, overall, for Canada. Although this was 35 units less than the previous year,
additions still outnumbered deletions, causing the available
count to rise by 2% or 796 rigs, Table 2.
GLOBAL OFFSHORE MOBILE FLEET EXPANDS
Rig-building accelerated in the offshore sector this year and
was the dominant reason that units were added to the fleet.
Overall attrition was slightly higher than last year, but did little
to offset the gains, due to the newly manufactured units.
Reductions to the fleet this year included 22 rigs that were
“Removed from Service,” some of which are undergoing conversions to non-drilling. This compares to 17 rigs that were
retired in the previous census. Three offshore units were reported as “Destroyed,” due to accidents, Table 3. If an offshore rig has not worked for more than five years, and does
not have upcoming contracts, it is removed from the census
until this status changes. This is to prevent rigs, which cannot be reactivated quickly, from being counted as available.
Although the census is able to track the majority of platform
and inland barge rigs in the U.S., the global mobile offshore

are particularly hard to obtain.
Another 63 brand-new rigs came online and entered the
census for the first time. The rate of increase in the fleet has
been especially noteworthy for the past six years, with 40 or
more rigs added each year. Another 81 units are scheduled
for worldwide delivery by the middle of 2015, according to
IHS. Even though all of these rigs will not meet that schedule,
another prolific year of fleet additions is likely, possibly surpassing the number of new units reported in the 2014 census.
In addition to these newbuilds, two offshore rigs also were
“Brought Back into Service.” No units were added after being
“Assembled from Parts.”
The available count for the global offshore mobile fleet
now stands at 890 units, a net increase of 40 rigs, and a 5%
increase from last year. The worldwide offshore mobile fleet is
widely distributed, with the Middle East in the lead, followed
by Southeast Asia, and the U.S., Fig. 4. Fleet composition by
specific rig type is shown in Fig. 5.
U.S. ACTIVITY SURGES
After showing a lagging year in 2013, U.S. drilling activity
picked up considerably this year, numbering 2,269 for 2014,
versus 2,055 last year. This resulted in a jump of about 10%,
and a rebound to the 2012 level. Active rigs rose to a greater
extent than available rigs this year, shrinking the gap between
the two and indicating stronger market conditions.
The methodology used to count active rigs for the NOV
census is different from other published rig counts. This census counts a rig as active, if it has “turned to the right” at any
time during a defined 45-day period in the late spring, this
year between May 9 and June 22. Other active counts typically report shorter windows of time, such as a week. When a
longer period is used to monitor activity, a larger pool of working rigs will be counted, and the count will be higher. This is a
better indication of activity, since fewer active rigs will be left
out of the count, due to relocations.
Rig utilization, the ratio of active to available rigs, is a statistic
that gives an indication of the demand/supply balance. Gains in
utilization can show increasing economic strength in the industry. This year, U.S. utilization has improved and is now 70%, rising
three percentage points since 2013. Although this year’s utilization is still below the historical average of 74%, it has reached the
70% mark, which typically indicates a healthier drilling market.

NATIONAL OILWELL VARCO’S 61ST ANNUAL RIG CENSUS
CENSUS GROUND RULES
Company sales regions were used for the geographical breakdown shown in Table 4.
Contractor-owned rigs are those belonging to companies whose primary business is offering drilling contracting services.
To be considered active, a rig must be drilling at least one day during the 45-day qualification period.
Only workable rotary rigs are included; cable tool rigs are excluded.
To be considered available, a rig must be able to go to work without requiring a significant capital expenditure.
Rotary land rigs stacked for an extended period of time, typically three years or longer, are not counted as available.
A rig must be capable of, and normally employed for, drilling deeper than 3,000 ft. Therefore, some shallow drilling rigs are
excluded, but this is necessary to ensure well-servicing rigs are not counted.
• Electric rigs include all those that transmit power from prime movers to electrically driven equipment.
• Inland barges include barge-mounted rigs that may be moved from one location to another via canal, bayou or river, and
drill in sheltered inland waters. Offshore rigs include stationary platform units (both self-contained and tender-supported),
bottom-supported mobile units, and floating rigs (both drill ships and semi-submersibles).

There were 985 available U.S. rigs that were inactive during
this year’s 45-day census period. These units may have been idle
as they waited for contracts or were being moved to their next
drilling location. These viable, but inactive rigs, were classified
according to the length of time that they have been idle. Rigs
stacked less than one year numbered 529; one to two years, 338;
and two to three years, 118. If land rigs are stacked longer than
three years, census rules state that they should be removed from
the available count. Assuming no changes occur in their status
over the coming year, most of the 78 rigs stacked for more than
two years will leave the census in 2015. Often, idle rigs are retired for other reasons before their stacked status targets them
for deletion. Rigs that require a large capital expenditure to be
up and running are removed from the fleet, and fall into the category “Removed from Service.”
Full-year utilization is another statistic used to measure
overall fleet dynamics. This percentage is the ratio of active to
available rigs that drilled at any time during the past year. Adding the 2,269 active rigs, to the 529 rigs stacked less than one
year, provides the total number of rigs that drilled between the
end of the 2013 census and the end of the 2014 census. This
full-year utilization figure indicates that rig owners used 2,798

units, or 86% of all available rigs this year. This compares with
91% during the past census period. So, although utilization increased during the census active period, full-year utilization
shows a decline. This indicates that the rig activity upswing
was a relatively recent occurrence.
Regional results are also computed for the census and often show variations based on area market conditions. Every
U.S. region had increases in available rigs for 2014, with the
exception of the Gulf Coast, which only declined by one rig.
Seven out of 10 regions experienced increases in rig activity.
The regional breakdown, which compares this year’s numbers
to 2013, is shown in Table 4. The regions with the greatest
percentage increases in activity were the Northeast states, up
31%; the Permian basin, up 29%; and the Southeast states, up
22%. It is believed that the Permian basin region, in particular,
experienced a bump in activity, due to increased horizontal
drilling. California was the area showing the greatest decline
in activity, down 15%. Utilization, by region, also shows mixed
results, with six out of 10 regions having increases.
The regional figures just mentioned are a combination of
land and offshore statistics. Looking only at U.S. land rigs,
however, we also see a modest increase in utilization. For
NATIONAL OILWELL VARCO’S 61ST ANNUAL RIG CENSUS
2014, land rig utilization was up to 70%,
versus 68% in 2013. The U.S. marine
fleet made a significant utilization gain
in 2014, rising another seven percentage
points to 69%. Rigs in greatest demand
were inland barge rigs at 78% utilization,
and floating rigs at 77%.
Analyzing the U.S. land and offshore
rigs by depth capacity, differences are visible between units in various ranges. The
rigs with the highest utilization, 78%, continue to be those in the 16,000-to-19,999ft range. Those with the lowest were the
most shallow (3,000 to 5,999 ft), with a
utilization of 57%, Table 5.
CANADIAN ACTIVITY RISES
SHARPLY
Canada experienced a noteworthy
increase in rig activity over the past year.
Since the census is taken every year in
the late spring and early summer, the
timing of the spring thaw, and the ensuing road restrictions put in place to avoid
environmental damage, often cause big
differences in year-to-year active count
statistics. For 2014, the active count
surged, as total units drilling numbered
352 during the 45-day active window.
This was a 22% increase from the same
time in 2013.
Utilization was pushed up this year,
because active rigs rose at an even greater rate than available rigs. Canadian utilization measured 44%, versus 37% the
previous year, Fig. 6. Subdividing the
fleet, more than 60% of available rigs in
Canada have drilling capacities between
6,000 and 12,999 ft. However, utilization
by depth capacity shows that demand is
now greatest for units in the 13,000-to15,999-ft range, where the demand-andsupply ratio comes in at 63%. We have
been told that some of the major players
are transitioning to deeper rigs, as drilling focuses more on the long-reach horizontal market.

NOV personnel are asked each year to
examine rig counts on a country-by-country basis and then calculate international rig utilization for the
primary areas. Accuracy in counting rigs can vary greatly, depending by country, but best-guess estimates are still included
in the averages. For 2014, all areas, with the exception of Asia
(including China), show increases in utilization. Many of the
increases since 2013 can be attributed to improved data sources
and record-keeping, as NOV attempts to better understand the
international market.

The latest counts in the FSU countries of Kazakhstan, Uzbekistan, Azerbaijan and Turkmenistan brought utilization
figures up for Europe (including the FSU). Asia (including
China), is especially difficult to get a handle on, due to secrecy
in the Chinese oil field, but our focus on this area facilitated
greater accuracy in determining the active-versus-idle count.
Middle Eastern rig counts were up significantly, as Saudi Arabia required more rigs to maintain its oil production levels.

In Latin America, overall utilization was up, although
it was due primarily to available rigs being down, instead
of overall activity being lower. Venezuela was the country
with the greatest increase in active rigs, due to the growth of
proven reserves in the Orinoco Belt. Mexico had somewhat
of a utilization increase, but overall rig counts were actually down, due primarily to PEMEX budget issues. In Brazil, Petrobras’ drilling activities were negatively influenced
by economic and political issues, which did cause activity to
decline, although rig utilization rose. Colombia saw rig activity decrease, as well, due to community issues and strikes in
oil states.
Worldwide, it is known that some areas have large numbers
of available rigs, but these units are often saddled with older
technology and may not be universally mobile or marketable.
Also, in some cases, available rigs are actually under contract
awaiting a project start, and are, therefore, unavailable for other work, Table 6.
MOBILE FLEET CONTINUES ITS ASCENT
The global offshore mobile fleet continued to show activity gains during the 45-day, census active window of May 9 to
June 22. The count rose to 725, an increase of 28 units or 4%.

land barge rigs, all offshore mobile units
are included in these figures. Utilization
didn’t change much in 2014 for the fleet, since both available
rigs and active rigs increased at similar rates. It fell just one
percentage point to 81%, Fig. 7.
In addition to looking at rig statistics, the census determines the total number of rig owners each year. The number
of owners has, essentially, leveled off for the last several years,
with the number of new drilling companies being added balancing closely with the number of companies ceasing operations. For 2014, the net number of rig owners increased slightly, by six companies, to 319, Fig. 8.
Drilling contractors always have owned considerably more
drilling rigs than operators, although the percentage of operator-owned rigs has grown slightly over the years. For 2014, the
operators’ portion of the fleet went up to 15%, a one-percentage-point increase. This translates to operators owning 472
rigs out of the 3,254 total units. Contractors own 85% of the
fleet, or 2,782 rigs.
Rig ownership in the U.S. also can be examined by the fleet
sizes of individual companies. When industry consolidation
began accelerating in the late 1980s, many companies grew
quickly as they bought up their competitors. These larger
companies (those with more than 20 rigs) continue to hold
the largest percentage of the fleet, again, this year, about 59%
of all rigs. However, when the market is good, new companies
tend to enter the drilling arena. There are 87 companies that
own a single rig and are able to capitalize on unique market
conditions in their area of expertise.
CREW CONCERNS
An annual survey is mailed out to drilling contractors every summer, inviting them to provide data about their current business environment and their opinions about the
industry. The 2014 survey was completed by 39 contractors, which is about 12% of all U.S. rig owners. A variety of
company sizes and regional areas were represented by this
year’s respondents.
Every year, owners are asked to rank a list of eight key issues that are typically of concern in the industry. In recent
years, three issues have continued to surface as the top concerns. “Crew Availability” was the number-one problem mentioned in 2014, moving “Rig Rates,” the top problem in 2013,
down in importance. The skilled labor shortage is becoming
acute and may be slowing the industry’s rate of growth.
The second-highest problem this year is “Government
Regulation,” remaining in the same position as last year.
For the past several years, there has been anxiety about new
mandates that could impact the drilling industry in a negative manner. Hydraulic fracturing, especially, has been on the
regulation forefront recently. “Rig Rates” were ranked as the

third-highest problem this year, after falling from the numberone ranking in 2013. Although rates affect profitability and are
always a concern, when active rig counts climb and business
is better, other issues tend to move up in importance. More
advanced mobile rigs may be able to demand higher rates in
some areas. However, better rig rates can only go so far in helping alleviate severe crew shortages, when crucial training time
is needed, Fig. 9.
Respondents are asked to share some of their company’s
current business figures. Labor rates on average have gone up
another 5% over the past year, and continue to rise as companies try to recruit and maintain crews. The cost of insurance
and benefits also has an impact on expenses, which continue
to escalate. Rig maintenance is another significant expense for
contractors, and it tends to increase annually. This year, contractors told us that maintenance costs were going to be about
2% higher than in 2013. There are still a number of older rigs
in the fleet that are very costly to maintain.
Contractors told us that, on average, their rig activity has
gone up almost 8%, compared to a year ago. This estimated
percentage is a little lower than the overall increase of 10%
measured in the census this year. Respondents also had an average increase of 2% in their land rig rates over the past year.
This increase is in line with higher rig activity, but does show
that rates have not kept up with activity levels. Contractors
seem optimistic that rig activity will continue to improve
over the next year, and they forecast an increase of almost
7% for 2015.
Along with horizontal drilling and hydraulic fracturing,
pad drilling has been one of the most important innovations in recent industry history. Therefore, a new question
was added to the survey this year, which asked contractors
to estimate what percentage of their wells used pad drilling.
This number was almost 31%, a significant percentage for a
technology that has been around for less than a decade. In
actuality, we know that in many of the big plays and among
some operators, an even higher percentage of wells are drilled
using pad drilling.
CONTRACTORS PLAN TO EXPAND FLEETS
The 2014 Contractor Survey also asked rig owners to
choose among several statements that best described their
company’s plans for the next five years. Recent economic prosperity, and an optimistic outlook, are apparent in this year’s
results. About 51% of contractors told us that they expect to
2013
No.1 Rig rates
No.2 Government regulations
No.3 Crew availability
2014
No.1 Crew availability
No.2 Government regulations
No.3 Rig rates
“Expand Current Fleet” in the next few years. With advanced
technology, rigs are able to optimize output at a faster rate, so
it isn’t surprising that a majority of contractors would expect
to increase profits by adding newer models to their fleets.
The next highest number of responses, 31%, included
contractors who predicted “No Plans for Change” in the next
five years. Fewer owners checked the boxes for “Unknown”
(10%), “Diversification into Other Businesses” (8%), “Pursuing International Opportunities” (5%), “Seeking Merger Opportunities” (5%), and “Downsizing Current Fleet” (3%). It
is important to note that contractors were allowed to choose
more than one category, so the total is greater than 100%.
FORECAST FOR 2015
The outlook for 2015 is more of a good news/bad news
scenario. Market conditions remain good in North America,
especially in the shale plays and other unconventional resources. Demand for the best rigs is expanding. Advances in
rig technology will continue to improve drilling efficiency,
safety, and the environmental impact of drilling.
Growth in land rigs is expected in Canada, Latin America
and the Middle East. The offshore global mobile fleet will
continue to add to its numbers with state-of-the art rigs. Furthermore, analysts expect the world’s energy consumption to
continue to grow.
However, combining higher rig efficiency with crude prices
that have slumped in recent days, does impact our optimism.
It’s possible that in 2015, if supplies are still high, U.S. utilization may fall slightly, since fewer rigs will be necessary for
new production. Hopefully, the recent commodity price dip is
just an aberration, and this dynamic industry will continue to
prosper in innovative ways.
