Session 2: Reservoir Characterisation for EOR
Moderators

Accurate reservoir characterisation is the pre-requisite for any successful EOR project. It can provide important insights into how the EOR processes in subsurface may occur. Recent advances in geophysics, laboratory simulation, and numerical modelling have provided numerous innovative approaches to optimising characterisation of reservoir properties and fluid behaviour.

Session 3: Gas EOR
Moderators
D.M. Anwar Raja Ibrahim, PetroMalaysia Sdn. Bhd.
Hemanta Sarma, The Petroleum Institute
Gas EOR (miscible and immiscible) primarily using CO2, has been gaining prominence in recent years due to the possibility of CO2 sequestration. Among the many injection schemes used, WAG process has been particularly significant. Foam is used with CO2 to improve sweep efficiency. Other gas EOR sources are nitrogen, flue gas and air.

Session 5: Pilot, Production Operations and Facility Design
Moderators
Mohamad Abu Bakar, PETRONAS Carigali Sdn. Bhd.
Jim Forrest, Schlumberger
The success of applying EOR in fieldwide developments depends upon a number of factors. This session will focus on the impact of pilot projects including injectivity testing, production operations, operational philosophy, and surface facilities design.
- Pilot projects and Injectivity Testing
- Are they necessary? cost/benefit analysis
- Designing them to accomplish the objective (rock/fluid interactions, reservoir characterisation, and operational Issues)
- Using the pilot project to confirm need and design for more complex completions (e.g. smart, ICD, Multi-lateral)
- Production Operations
- Logistical – onshore and offshore
- Operational experience levels
- Shared injection wells and pipelines (e.g. injection pipelines, wellheads, WAG wellhead operation)
- Reservoir and Operational Surveillance (P, T, Rates, Corrosion, Scale, Sanding, etc.)
- Surface Facilities Design
- Facilities integrity (mature fields)
- Optimum design selection (compression, dehydration, separation, and treatment)
- Special considerations for EOR processes (material selection)
