Introduction
• The oil & gas industry continues to represent a
propulsive base segment to maintain the
developing of the countries.
• This
fact
increases
the
activities
of
telecommunications sector, that is responsible to
provide communications networking solutions.
• One area to be detached is the pre-salt
exploitation that represents a new era to oil and
gas production and a great challenging to
engineers.

Onshore systems
• In the production phase, the oil can only
come to the surface due to fluid pressure
existing within the reservoir. The wells are
called insurgents.
• When this not occurs, it takes additional
energy from the ground to raise the well
fluids to the surface.
• The mechanical pump is an artificial lift
method, among several others.

Onshore systems - Automation
• Automation frequency bands
– 5.8 GHz – unlicensed band
(Line of sight is required)
– 2.4 GHz – unlicensed band
(Line of sight is required)
– 1.5 GHz – licensed band (protected) – WIMAX
– 450 MHz – licensed band (protected)
• No protection against interference.
• Propagation mechanisms best suited to areas with rugged terrain.

Onshore systems - Automation
• Example of coverage area to automation.

Oil & Gas Communications, Rio de Janeiro, GVF Conference, April 19 & 20
Onshore systems - Oil & pipelines
• The successful construction of pipelines, its
maintenance and automation depends directly
on reliable telecommunication services.
10
Oil & Gas Communications, Rio de Janeiro, GVF Conference, April 19 & 20
Onshore systems - Oil & gas pipelines
• The implemented solutions through terrestrial
systems are communications in VHF (148 to 174
MHz) using repeaters and trunking UHF (800 MHz)
systems.
11
Oil & Gas Communications, Rio de Janeiro, GVF Conference, April 19 & 20
Onshore systems - Oil & gas pipelines
• The equipment need to follow the NBR 14787 from
Brazilian Association of Technical Standards - ABNT.
• Just intrinsically safe radios can operate in explosive
atmosphere, like oil refineries and platforms.
What rule
are you
following?
12
Oil & Gas Communications, Rio de Janeiro, GVF Conference, April 19 & 20
Onshore systems - Oil & pipelines
• Communications coverage along the pipelines.
• Intrinsically Safe Radios (Used in critical locations).
• Frequency bands (Affected by new regulatory issues).
– VHF (148 to 174 MHz) – VHF system uses repeaters.
– UHF (800 MHz) - Trunking system uses the radio base stations.
• Some part of the radios will be modernized, but the company still
have old radios, which however, still has a long shelf life.
13
Oil & Gas Communications, Rio de Janeiro, GVF Conference, April 19 & 20
Production in forest area
• The Urucu province is a huge complex of extracting oil and natural
gas in the heart of the Amazon rainforest.
• The natural gas extracted from the mine has begun to flow Urucu to
Manaus via a pipeline with 660 kilometers.
• Propagation in the forest is very complex, the coverage is reduced.
14
Oil & Gas Communications, Rio de Janeiro, GVF Conference, April 19 & 20
Production in Forest area - Aggressive environment
• The pipe line from Urucu to Manaus has 660 kilometers.
• The forest goes slowly recovering the built-up areas, due to the
action of rain and growth of trees and vegetation.

Offshore communication
• WIMAX technology – 3,5 GHz
• Satellite network (ku band)
• Automatic Dependent Surveillance
Broadcast (ADS-B)
-
– Aircraft equipped with Global Positioning
System (GPS) receivers can transmit their
location and altitude to other nearby aircraft
and to air traffic control.
• VHF and UHF systems with repeaters to
communicate with platforms and ships.

Unmanned Aerial Vehicle - UAV
• There is an intention to use UAV to monitor pipe
lines and offshore areas, to take advance
warning of any instances of anomalies.
22

Unmanned Aerial Vehicle - UAV
• Example of images acquired by a UAV into an
area where there was an oil spill.
23

Unmanned Aerial Vehicle - UAV
• The areas monitoring with UAV can minimize accidents
on oil industries.
24

Regulatory Issues
• The Brazilian Telecommunication Agency - ANATEL implemented
some new rules to VHF, UHF and SHF frequency bands.
• Some of that changes affected PETROBRAS:
• 148 to 174 MHz – Digital transceiver / channel 12,5 KHz.
• 800 MHz – Digital modulation to trunking system.
• 3,5 GHz – WIMAX technology to use only to offshore from 50 km
from the coast (private users).
• ADS-B and UAV need to follow the Aeronautical and ANATEL
regulations.
25
Oil & Gas Communications, Rio de Janeiro, GVF Conference, April 19 & 20
Conclusion
• Information in this presentation provides a
good idea about the challenge of the
telecommunications sector in keeping
PETROBRAS communication with a high
reliability in operation.
