1. Value Creation Through R&D: Autonomous Inflow Control Valve (AICV®) ‘Autonomous gas/water shut-off in field with gas/water breakthrough’

2. The Challenge
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
Reduced oil production
Reduced recovery
Requires large gas/water handling systems
Gas
Oil
Water

4. AICV® - Autonomous Inflow Control Valve
Autonomous; requires no external power or control
Simple; uncomplicated with low risk of failure
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)
Flexible; can be adjusted to fit the reservoir strategy

5. The Troll Case
SPE , Increased oil production at Troll by autonomous inflow control with RCP valves, Halvorsen et al. (2012):
“RCP valves have been successfully tested and implemented in three wells at the Troll field. The production experiences from the branch completed with RCP valves in P-13 and in addition from the well P21 with RCP in both branches are very encouraging. As for April 2012, almost 1,5 years of production, the GOR in the branch completed with RCP valves is 1/3 of the GOR in the branch completed with ICD’s. The cumulative oil production is approximately 20 % higher in the branch completed with RCP valves. The wells completed with RCP valves are producing at a high oil rate for a longer period of time prior to gas breakthrough compared to typical Troll wells.”

6. What is the most simple and efficient way to stop unwanted gas and water production?
Produce the gas/water, and then separate the gas and water at the platform.
Build a subsea factory where you separate the gas/water.
Stop the gas and water in the reservoir.

7. Application Areas of AICV®
Stop gas in oil fields
Stop water in (heavy) oil field
Stop steam in bitumen production
Stop CO2 in EOR

8. Our experience - Technology Development
To get research & development funding is easy
To find investors/capital is easy
To find oil companies in Norway that wish to pilot new technology is hard
To find oil companies in Middle East that wish to pilot new technology is easier
To qualify oil technology in Norway is (too) hard
Oil companies in Norway doesn’t like smaller companies
Many doesn’t welcome new technology
Technology development and innovation is challenging, but very funny
