Pilot projects are a major step in moving to full implementations and can take anywhere from 5 to 10 years. We can help you plan pilots with a focus on fast and efficient data collection. Pilot objectives may include the following assessment of the enhanced oil recovery (EOR) process for full-field development:
- Evaluate recovery efficiency.
- Assess the effects of reservoir geology on performance.
- Reduce technical and economic risk in production forecasts.
- Calibrate reservoir simulation models.
- Identify operational issues and concerns.
- Assess the effects of development options on recovery.
- Assess environmental impact.
- Evaluate operating strategy to improve economics and recovery.
Sufficient time must be allowed for the flood front to progress through the pilot. The goal is to either reduce risks sufficiently to be able to implement an EOR method in all or a part of the field, or to eliminate it as incompatible with objectives.
In addition to support for pilot projects, we offer an innovative approach—MiniPilot medium-scale EOR evaluation—comprising intelligent wells strategically positioned across the reservoir. MiniPilot evaluations can both inform the way forward in small steps and significantly reduce the time to production.
Our strategy is to use key technologies to create an initial model and well design for short-spacing well patterns that optimize distribution of the injected fluid. Multiwell high-resolution measurements provide early production performance indicators, enabling informed development decisions to be taken.
The most advanced line of minimally damaging and HSE-acceptable reservoir drill-in fluids (RDFs) includes the only RDF that drills with oil-base efficiency, but with the completion simplicity of a water-base drilling fluid. This product has a field-proven record of success in numerous injector wells.
Innovative cementing technologies help achieve zonal isolation for the life of your well, reduce the risk of CO2 degradation, and minimize the risk of leaks from underground gas storage (UGS) wells.
Monitoring technologies inform operators how the reservoir is responding, enabling them to control injection and other parameters to maximize production. Various logging tools provide fluid volumes and saturations. Deep reading technologies use physical measurements of the interwell space for fluid front monitoring. Distributed temperature profiles help identify the time, location, and reason for changes in flow, while 4D, or time-lapse, seismic depicts changes in the reservoir caused by injection or production.
EOR operations can require considerable volumes of water for injection, so efficient management of water is key to ensure minimal environmental impact.
