UK-based Ithaca Energy, the operator of the Captain field located on the edge of the outer Moray Firth, UK, has sanctioned Captain Enhanced Oil Recovery (EOR) Stage 2 project.
The sanction of the project in the UK Central North Sea comes after the company received Field Development Plan Addendum consent from the Oil and Gas Authority (OGA).
“EOR Stage 2 is the next phase of development at our Captain Field and is building on the success of EOR Stage 1. The project is designed to significantly increase hydrocarbon recovery by injecting polymerized water into the reservoir through additional subsea wells, subsea infrastructure and new topsides facilities,” Ithaca Energy said.
“Stage 1 of the project has demonstrated that polymer EOR technology works, with the production response in line with or better than expected across all injection patterns, helping us maximize economic recovery within the UK Continental Shelf (UKCS),” Ithaca Energy added.
“Platform modifications will take place in 2021, ahead of subsea work scopes and drilling across 2022 and 2023. First oil expected in early 2023, before reaching a peak in 2026,” the spokesperson added.
Jongwoo Kim, Chief Executive Officer, Dana Petroleum, said: “Dana has maintained an interest in the Captain field for many years. It is particularly exciting to see how extensive research alongside the application of new technology is being used with great efficiency to enhance recovery. We are really pleased to have worked collaboratively with Ithaca Energy to support this important project.”
The Captain field was discovered in 1977, in Block 13/22a located on the edge of the outer Moray Firth. The billion-barrel field achieved first production in March 1997 – over 20 years ago – thanks to technology developments in horizontal drilling and down-hole pump technology. The installation comprises a Wellhead Protector Platform and Bridge Linked Platform connected to a Floating Production, Storage and Offloading vessel.
