Case study: Latin America

Electric intelligent completion,
fiber optic monitoring forwater injector well a world first
To improve oil recovery, an operatorin Latin America had used traditional
water injector wells in a field withmultiple injection-production zones.
The operator was unable to gauge theamount of water that flowed into thedifferent production zones. Because of
the differing permeability and porosityof the multi-segmented zones, thewater injection could not be optimized
to manage the waterflood front thatwould maximize sweep efficiency andoil recovery.
To help optimize the water injection anddecrease lost production, the operator
turned to Baker Hughes to install theMultiNode™ all-electric intelligent wellsystem and the SureVIEW™ distributed
acoustic sensing (DAS) system. The
combined systems enabled controlled
and monitored water injection into theindividual zones, previously impossible
with traditional water injection
completion equipment.
Throughout the project, Baker Hughes
worked seamlessly with the customer’s
team of engineers, incorporating

the strengths of local personnel
and mobilized global experts fromthe intelligent production systems
engineering, product line, andoperations team.
The intelligent completion design for thismature reservoir application consistedof a cased-hole well separated into
four individual zones for water injection.
A MultiNode™ electronic flow controlvalve (eFCV) was installed in eachof the four injection zones along witha SureVIEW fiber optic DAS system
deployed throughout the completion
for real-time dynamic injection flow
allocation and monitoring into each of
the four zones. The eFCV valves can beincrementally opened or closed fromthe surface without well intervention
to alter the injection profile, increaserecovery from hydrocarbon-rich zones,
and delay water breakthrough. Remotely
controlling injection rates into the multisegmented zones improves the service
life of the injection operations, eliminates
future intervention costs, and increases
ultimate recovery.

Challenges• Control and monitor water
injection across four individualzones of a depleted field withdiffering water injection profiles• Deploy emerging technology,
previously unused for water
injection applications• Install equipment into narrow
downhole production zones
with very tight space-out
requirements• Manage operational complexity
and cost of water injectionResults• Increased production fromcorresponding producer wells by
62% and reduced operating costs
by 30% after one year
• Delivered first four-zone,
intelligent injection completion
system in the world• Enabled the operator to measureinjection into each zone andestimate how a change to thechoke position would alter theinjection operations

By installing a MultiNode all-electric intelligent
completion system coupled with the SureVIEWDAS system, the operator can now remotely
control and monitor water injection in all fourindividual zones. In addition, the intelligent
completion provides the ability to continuously
acquire, aggregate, transmit, store, process,analyze and visualize gigabytes of surveillancedata from a variety of multi-sensors forreal-time monitoring and optimization of theintelligent injection well operations.
The Baker Hughes team performed thoroughcleanout runs and deployed the completion
without rotation or circulation.
Baker Hughes deployed the precise
combination of innovative products andexpertise to ensure the success of thiscompletion installation. Experienced andknowledgeable, the crew delivered an
innovative, reliable, and versatile intelligent
completion system that will increase
production rates, reduce workover costs, andenhance recovery over the life of the well.
