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.

SmartWell technology enables exploitation ofmarginal reserves and acceleration of

hydrocarbon production through comminglingof reservoirs.

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

HSE incidents

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


18/21

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
