Crude oil production usually includes three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore.
Only about 10 percent of a reservoir’s original oil in place is typically produced during primary recovery. Secondary recovery techniques extend a field’s productive life generally by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place.
Maximising production from existing assets is more crucial than ever in today’s competitive energy landscape. Secondary and Enhanced Oil Recovery (EOR) techniques offer significant opportunities to boost output
There are four main EOR techniques: carbon dioxide (CO2) injection, other gas injection, thermal EOR, and chemical EOR. Carbon dioxide injection, known as CO2-EOR, is the most common method. In this method, CO2 is injected into a depleted oil field and is mostly left underground.
Secc is collaborating with industry leaders to streamline secondary and enhance EOR operations by providing innovative solutions that improve accessibility and efficiency and ultimately allowing EOR operations to be carried out from vessels rather than host facilities – refer to the Siri Knutsen case study for more information.
The Hot Make Hot Break Coupling offers unparalleled time and cost efficiency by enabling quick, secure, and flexible connections without the need for extensive intervention infrastructure. Operators can perform essential secondary or tertiary gas/fluid injections on a regular schedule, ensuring the field’s production is optimised.
Secc’s EQD coupling technology not only reduces operational downtime and costs but also minimizes risks associated with traditional recovery methods. By leveraging these solutions, operators can achieve higher recovery rates, extend the productive life of their wells, and improve the overall economics of their secondary and EOR projects. With a focus on innovation and collaboration, Secc is helping to redefine how the industry approaches enhanced oil recovery.
