Motivation Increased Recovery

2

Increased production and recovery is necessary

Averaged recovery is 46 %, NCS

1 % increased recovery gives 70 billion $, NCS

Lower recovery factors in most of the world

Norwegian Continental Shelf (NCS):

Why AICV? Long horizontal wells to ensure maximum reservoir contact

Friction inside the well

Heterogeneous reservoirs (permeability and formation variations)

Non-uniform well drainage creates gas/water breakthrough

Gives reduced production

Gives reduced recovery

Requires large gas/water handling systems

State of the art technology (ICD) can delay the breakthrough problem: but cannot stop the gas/water problem at breakthrough

Gas

Oil

Water

AICV - Autonomous Inflow Control Valve Combines the best from ICD, AICD and ICV:

Autonomous; requires no external power or control

Effective; can stop the gas/water completely

Reversible; allow oil production after an earlier breakthrough

Distributed; no limit in number of zones

Retrofitable; can be installed in new and old wells

Compatible; with standard completion (screens)

Design of the AICV The pressure in the pilot flow

controls the main flow

Large flexibility of design/application;

ICD strength

Laminar flow and turbulent flow element

Area inlet and area pressure chamber

Oil Water Pilot-

AICV Applications Based on the viscosity difference between the fluids the AICV stops the unwanted fluid autonomously. 1. Ultra Light Oil, API > 34

Gas shut-off, Reservoir viscosity less than 2 cP

2. Light Oil, 34 < API < 31 Gas and water shut-off, Reservoir viscosity 2- 5 cP

3. Medium Oil, 22 < API < 31 Gas and water shut-off, Reservoir viscosity 5-50 cP

4. Heavy Oil, 10 < API < 22 Gas and water shut-off, Viscosity larger than 50 cP

5. Extra Heavy Oil / bitumen, API < 10 Steam and water shut-off for SAGD

6. AICV for gas wells Liquid shut-off

7. AICV for oil wells with CO2 injection (EOR) CO2 Gas & Water shut-off

Summary AICV

Shut-off unwanted fluid (gas, water) production Reduced GOR, WC

Increased production

Increased recovery

Reduced investment

Only known technology

Huge potential

Field tests are planned for 2015 Canada

Saudi Arabia
