Polymer flooding contributes toward meeting net-zero production emissions by reducing carbon dioxide emissions per barrel by 2-6 times. This reduction is primarily achieved through a more efficient sweep of oil within the reservoir.
Utilizing water injection to sweep oil toward producing wells is a widely deployed process. The difficulties associated with displacing, producing, and recovering oil from a reservoir can be improved through polymer EOR technologies:
Backed by decades of successful field applications, polymer flooding represents a proven recovery technique to increase production efficiency and extends the economic producing life of conventional oil resources. Providing improved mobility control, the increased swept oil volume results in decreased water production and a sustained period of higher oil rate.
Polymer fluid systems are also part of Chemical Enhanced Oil Recovery (CEOR) schemes, such as Surfactant Polymer (SP) and Alkalai Surfactant Polymer (ASP) floods, which are applied to access bypassed capillary trapped oil.
SNF manufactures an extensive range of polymers in both powder and liquid inverse emulsion form for application to oil reservoirs of varying conditions. Best polymer solutions can be selected based on fundamental criteria pertaining to key reservoir properties and fluids, including:
Optimal sweep efficiency is the goal of any secondary/tertiary recovery flooding process. Poor sweep efficiency strands oil and can be compounded by geological features, resulting in the channeling of injected fluids and high water cut. To correct poor sweep efficiency, in-depth reservoir treatment strategies are required and are achievable with appropriate polymer gel systems and designs.
SNF has introduced EASEOR™ as a smart monitoring system for Enhanced Oil Recovery applications.
Based on IIoT technologies (Industrial Internet of Things, i.e., using sensors and analytics), EASEOR™ solution enables data collection to improve projects’ efficiency, productivity and safety.
SNF’s expertise in polymer chemistry and engineering allows any polymer flood project to be completed in full with customized solutions. Due to the unique nature of each oilfield, we offer tailored polymer and equipment solutions, from conceptual studies through full-field operations.
