Highlights Include:

Balol Field (India) – Phase-I Application – In-Situ Combustion
A remarkable success, this commercial scale in-situ combustion application achieved an incremental recovery factor of 43% and a maximum water-cut drop of 54.7%. Combustion and production performance monitoring confirmed the ignition and identified the combustion mode.

Mitsue Field (Canada) – Unit No. 1 Application – Hydrocarbon WAG Miscible Flood
Canada’s first commercial miscible EOR project, delivering an expected ultimate incremental recovery factor of 11.6% and an individual well incremental EUR of 285 MBO. Gross and net gas utilisation averaged 4.32 MCF/BO and 2.66 MCF/BO, respectively. Project success was underpinned by effective reservoir management, enabled by comprehensive monitoring and conformance improvement.

Shuanghe Field (China) – Shuanghe District Pilot – Alkaline-Surfactant-Polymer (ASP) Flood
This ASP pilot achieved an incremental recovery factor of 10.7%, with an alkali utilization of 9.26 kg/BO, a surfactant utilization of 3.56 kg/BO, and a polymer utilization of 3.85 kg/BO. Individual well incremental EUR amounted to 86.7 MBO. The weak alkali ASP system performed well with the targeted reservoir sands, successfully mitigated scaling problems. Timely application of cross-linked polymer injection for conformance control proved effective in modifying profiles and preventing channeling of the low IFT ASP system.

Tsimiroro Field (Madagascar) – Main T01 Compartment Pilot – Continuous Steam Injection
Targeting extra-heavy oil with viscosity of 15,729 cP, this thermal EOR project was expected to achieve an incremental recovery of 54%, with favourable steam utilization of 5.2 BS-CWE/BO. Project success was driven by reservoir preheating through CSS treatment, regular temperature profile measuring from observation wells, and effective workovers (such as plugging back of the lower reservoir unit, and steam leak and damaged casing repair).

Wellman Field (USA) – Fieldwide Project – CO₂ Miscible Flood
This successful GOGD-combined CO₂ miscible flood achieved an incremental recovery factor of 8.3% along with a maximum water-cut drop of 14%, and was expected to reach an ultimate incremental recovery factor of 16.7%. This project provides valuable experiences in reservoir management, including miscibility preservation, CO₂/oil interface maintenance, gas production control and recompletion strategies.
