Enhanced Oil Recovery

Increase recovery factors in every reservoir

Produce more from your current fields

The traditional way of considering EOR only after initial production decline needs to change.

In this collection of videos, our technical experts discuss why planning for EOR from the earliest field development stages is the most efficient way to maximize ultimate recovery over the long term.

Controlling EOR means you can optimize its outcome.

Holistic, systematic approach

Figuring out how to mobilize remaining oil is just the start. Pushing that mobilized incremental barrel of oil to the surface through the heterogeneities of the reservoir via challenging wells and completions requires mastering all disciplines of the E&P value chain—from reservoir characterization to artificial lift.

This requires that all enablers of the EOR project space, from pore to stock tank, work in the right synchronization per the EOR plan. It also requires managing data from many sources, from the reservoir to surface systems, and all disciplines and scales.

What is measured can be managed, log

Historically, EOR implementation was mostly an afterthought, considered only when primary and secondary production means were exhausted. Most fields today are past their prime, and traditional lengthy EOR investigations simply don't fit into the workflow of modern economics.

The fact is, achieving the maximum recovery factor requires initiating EOR at the early planning stages and monitoring events as they unfold so you can control and optimize the outcome.

Our approach to EOR provides an efficient "concept-to-field-trial" roadmap to boost production far faster compared with traditional workflows. And to ensure—not just promise—long-term success, we deploy proper monitoring and control systems to display your project's results in front-line view.

EOR projects of the past largely lacked sensing, testing, and intelligent control technologies. Not anymore.

Our solution for unlocking full productivity is designing and implementing EOR-specific monitoring and control systems that pull together fit-for-purpose EOR agents, proven recovery conformance, and proper operation of wells and surface systems.

We leverage our deep subsurface capabilities and multiscale measurement technologies to craft EOR-specific monitoring and control systems that are effective for the entire project environment—from pore to surface facilities. These digital breakthroughs are crucial to improving the likelihood that EOR projects exceed expectations.

Step 1: Efficient assessment

We start by identifying the most suitable EOR method(s) for your specific environment and reservoir type. Then, we develop a custom approach to take the concept to the field as fast as possible. Our smart systems guide us to determine the optimal number, location, and size of pilots to ensure that the engineering design is compatible with reservoir conditions.

Step 2: Faster field trials toward field upscaling

Next, we focus on executing the field trial significantly faster compared with historical projects. After fine-tuning the EOR method, we prioritize field expansion using input from field-proven pilots and existing wellbores.

Step 3: Digital monitoring and controls to ensure success

From input well logs, laboratory information, fluid data, core samples, completion and production data, and fiber-optic sensors, we translate all EOR-relevant information into actionable recommendations and management plans. Coupled with the ability to collaborate with our experts, the industry’s most comprehensive portfolio of services and technology, and our global operations footprint, these new insights let you to optimize the ongoing EOR project.
