The Field Geologist Development Program
The Field Geology Development Program is designed to develop recent geology graduates in field positions, allowing
them to build their skills and experience while contributing profitably and quality service to the company. As
participants develop under the program, we increase their responsibility and provide training in other areas, such as
geosteering and field supervision. Not only do they become first-class field geologists, they also position themselves for
a long-term career path with Nomac Services. As participants near the end of their one year program, they begin to
target a career path. In addition to field geology positions within the company, they can also choose a career path that
includes field supervision as well as staff and management positions. The program is comprised of three phases:
Phase I (Field Geologist Trainee I)


Introduction - The FGDP begins with a two-week intensive Training Phase in which geologists learn Nomac
Services’ processes, procedures and company culture. The trainee learns about safety, drilling, communication,
quality, software and equipment—everything necessary to be a productive Field Geologist. It is a rigorous
training program that builds the basic skills they need in the field and camaraderie with other program
participants.
Initial Field Phase - Following the two-week training phase, participants work in the operation as Field Geologist
Trainee I for approximately four months to put their training into practice. During this time they not only gain
experience in operating Nomac Services production and quality processes but begin to develop ideas for
improving or expanding the company’s products, services and training. Training objectives and milestones will
be used to assess the competency of the Field Geologist and determine the readiness for advancement in the
program.
Phase II (Field Geologist Trainee II)


Classroom Review - Upon completion of Initial Field Phase, participants return to the classroom for a one-week
Interactive Phase of training, discussion and quality improvement. Each participant’s quality records for the
Initial Field Phase are reviewed, along with any training/process improvement suggestions they developed in
their time in the field. Participants also study advanced courses and begin to learn how various staff functions at
NOMAC Services. The goal of this phase is to improve both the participant’s skills and the company’s ability to
deliver exceptional service.
Intermediate Field Phase - Participants proceed to an Intermediate Field Phase where they continue to practice
and improve their skills as well as begin to mentor other Trainees in areas of geology, communication and
quality. As part of this phase, participants also develop their own specialized geology training course or
problem/solution project for other employees based upon their specific experience. Field Geologist Trainee II
will also return to the operations center at some point during this phase to complete a two-week rotation in
Quality Control. Training objectives and milestones will be used to assess the competency of the Field Geologist
and determine the readiness for advancement in the program.
Phase III (Field Geologist Trainee III)

Classroom Review – Upon completion of the Intermediate Field Phase, participants return to the classroom for a
one-week Interactive Phase of training specifically targeting Geosteering. Participants will be trained on the
theories, procedures, and applications of the geosteering process. Each participant will work with specific
software and practice correlating data sets, perform mathematical calculations, generate reports, and steer


“mock” wells. The goal of this phase is to improve the participant’s knowledge of geosteering and give them the
skills necessary to advance to the next stage.
Advanced Field Phase – Participants proceed to an Advanced Field Phase to continue the with field experience.
Field Geologist in this phase will assume more of a leadership role in the teams and participate in advance
techniques. Field Geologist Trainee III will also return to the Geosteering Operation Center (GOC) for a twoweek rotation in geosteering operations. This is designed to determine the ability and skill of the participants.
Training objectives and milestones will be used to assess the competency of the Field Geologist and determine
the readiness for advancement in other opportunities.

Field Geology
What is field geology? Before the FGDP, there was no such thing as field geology. The service was known as “mud
logging”. Nomac Services changed the industry by providing educated, young professionals a chance to gain operational
experience in the field. Science based college graduates have the opportunity to build a foundation of experience that
will provide them the skills necessary to be a successful Geologist in the oil and gas industry.
Field geology is an oilfield service that is rendered during drilling. Drilling an oil or gas well is accomplished by using a
special drilling bit to grind a hole through rock. The drill bit is on the bottom of a long string of pipe that is used to turn
the bit. A special lubricant, known as drilling mud, is forced down through the pipe and allowed to flow back up the sides
of the hole. The drilling mud washes the ground up bits of rock out of the hole so that the drill bit is constantly in
contact with new rock. The mud flows over a series of filters to remove the bits of rock so that the mud can be reused.

Field geologists have three primary responsibilities during the drilling process:



First, field geologist are responsible for physically inspecting and reporting on the rock cuttings, known as rock
“samples,” that are removed from the hole by the drilling mud. Roughnecks on the rig collect and bag the rock
samples periodically based upon instructions from the drilling geologist (typically, every 10 or 30 feet). Field
geologists receive the rock samples, clean and organize them, and analyze them under a microscope. Using the
samples, they make a map of the rock formation layers through which the well is drilled and describe the
characteristics found in each rock layer.
Second, field geologists are responsible for analyzing and plotting the natural gas that is released from the rock
during drilling. As the bit cuts through the rock layers, natural gas under pressure is released into the drilling
mud. Using sophisticated tools and computer analysis, geologists plot the rate of drill bit penetration and
associated natural gas characteristics for each foot of drilling depth.
Finally, field geologists are responsible for communicating with the exploration geologist. They act as the
exploration geologist’s “eyes and ears” at the drill site, discussing the various events that occur during drilling
with other well site personnel and reporting those events to geologists in the exploration office. It is critical for
field geologists to develop a rapport and relationship with other well site personnel in order to gather and
report drilling information.
Each day, and at the conclusion of the well, the mud log is sent to the geologist and a variety of other interested parties
to document the conditions present during drilling, the events that occurred, and the content and characteristics of the
rock layers that were penetrated.
What is a typical day for a field geologist? In the oilfield, drilling is a 24x7x365 operation. Exploration geologists typically
turn in a report for all their wells in the early morning, so a field geologist’s day starts early enough to ensure that
exploration geologist has the information they need to prepare their report. A typical day might start at approximately 2
– 4 a.m., depending upon the daily report time specified by the geologist. The field geologist collects, analyzes and
describes the samples gathered since the last report, discusses drilling events with the personnel at the site, prepares
the mud log, produces a morning report, and reviews the information with the Nomac Services Quality Control
department — all in time to get the report to the geologist somewhere between 5 – 7 a.m. After submitting the report,
the field geologist prepares everything for the next day’s cycle by organizing and storing samples, maintaining
equipment, cleaning the trailer, meeting with well site personnel, and planning the next 24 hours with the Field
Supervisor. Occasionally throughout the day, the field geologist checks equipment performance (using the Internet) and,
if required, provides updates of drilling events to the exploration geologist and wellsite personnel.
What is a typical work environment? Oil wells are drilled almost exclusively in relatively remote rural areas. The typical
well is located in an open field and is accessed by taking a dirt or gravel road that was built especially for drilling the well.
There is no “office work” for a field geologist — everything happens at the well site. Field Geologist communicates with
Field Supervisors, exploration geologists and other company personnel using company-provided laptop or desktop
computers, email and cell phones.
Nomac Services has trailers that are moved to the location and “rigged up” by supervisors or dedicated field support
personnel. Field geologists are expected to support this process by running lines, setting up equipment and checking all
equipment at the time of rig up to ensure it is working properly, then reviewing equipment performance each day and
reporting problems to operations personnel.

What are the traits of a good field geologist?



Dedication – a good field geologist is dedicated to doing their job right the first time, keeping the customer
happy and continually improving upon their performance. Nomac Services will provide extensive training and
guidance, but a good field geologist must have an internal drive for personal and professional success and
growth. The hours are long and the conditions can be difficult at times; one must be willing to do the hard
things to build the experience needed to have a successful career in the oil and gas industry.
Computer Aptitude – if you cannot perform basic computer tasks, you will not be successful as a field geologist.
Specifically, you must be able to use email and Microsoft office applications, including Microsoft Excel. You
must have basic knowledge of computer systems and how they communicate to other systems. You must have
a basic mechanical aptitude for working with small hand tools. These are simple but critical applications.
Discipline – field geologists affords a significant amount of independence and autonomy. You must be able to
provide your own structure, motivate yourself to complete everything on time in accordance with the quality
standards, and continually learn to improve upon your own performance. There are no babysitters in the oilfield
– success is up to you.
