SmartWell Completion Technology
A SmartWell completion enables the
operator to remotely monitor and
control well inflow or injection
downhole, at the reservoir, with no
physical intervention, to permit
optimization of well, production and
reservoir management processes.

World-wide, the oil industryproduces more water than oil!
SmartWell completions permit the operatorto optimize reserve recovery bymanagement of injection and productionprofiles.
And reduce the amount of water produced
too!

Waterflood and EOROptimisation
Smartwell technology allows the
operator to regulate or shut-off
production or injection at eachreservoir zone or each multi-
lateral junction, without
intervention.

Whats Wrong With This Picture?Nothing if you like to invest
in lots of wells and lots of
surface infrastructure!Minimize CAPEX & OPEX
Optimization of surfacefacilities: leveraged
wellbores
Eliminate interventions:reduce risk of well loss or

Case Study 1Horizontal w/ Laterals & ESPsSweep and water breakthrough problems. Average waterbreakthrough for the field was 75%.
Challenge
Carbonate Reservoir
4 to 7 open hole laterals
Reduce length of laterals to improve
efficiency
ESP was a requirement

Solution
Use of an intelligent completion to:
control contribution of laterals
reduce water cut of produced fluids
improve waterflood efficiency
reduce dehydration and water disposal costs
Implementation
Successfully installed 4 Zone Digital
Hydraulic System Integrated with an ESP
Hydraulic disconnect separates Upper
(ESP) from Lower (Flow Control DigitalHydraulic) completion
