Raising the recovery factor above 40% is a challenge. EOR, sometimes called tertiary recovery, is an important part of improving total production. More often, asset managers and field planners consider various EOR methods as part of the initial field development plan. Yet questions remain with respect to the technical and economic viability – ‘how much’, ‘where’, ‘what’, etc. With a range of technologies for EOR, we can help you start with small-scale tests and studies, and develop a way forward that reduces uncertainty at each step.
The screening process begins with gathering as much reservoir data as possible and developing a coherent package to compare with the screening criteria for various EOR methods. After narrowing the choices, the evaluation moves into the laboratory to investigate rock and fluid properties, and to conduct flow studies. Chemical EOR can be evaluated with a single-well wireline service that yields results in a matter of days. Engineers and geoscientists use the available data to develop updated static and dynamic reservoir models, and to simulate the effects of different EOR methods in order to choose the optimum one.
Pilot studies reduce uncertainty and operating risk, helping to plan a way forward for large-scale developments. In addition to the design of pilot projects, we can provide injection, production, and surveillance equipment and facilities. Our global knowledge of EOR pilots and operational experience can help accelerate your projects. EOR-specific technologies form part of our complete portfolio of services and products for well placement, construction, completion, monitoring, and production.
An increasingly detailed reservoir model is extended from the pilot to the scale of the development area. The final drilling and completion activities, as well as the surface facilities and transport design are determined by this model. Production monitoring from the ongoing pilot can be used to optimize the expanded operations to maintain planned production.
Operators worldwide have come to rely on M-I SWACO production technologies to mitigate problems that jeopardize production. We offer a full suite of targeted solutions for all your production-related problems. Our portfolio ranges from specialty chemicals to inhibit corrosion, hydrogen sulfide, or gas-hydrates to customized produced-water-and-sand management solutions.
