Kuwait is keen in developing the shallow Miocene Heavy Oil resources of Ratqa Lower Fars. EOR screening studies indicate thermal methods of Cyclic Steam Stimulation (CSS) and Steamflood as most promising technologies for developing this resource and meeting KOC goals. Thermal development was tried earlier in this field. In 1980's two CSS pilots were carried out that are considered successful. Steam Flood was also planned at that time but the project got stalled due to the Gulf War. Facilities got destroyed during that war. The present paper describes how thermal simulation techniques were used to design a new and improved thermal pilot, by matching the old CSS pilot performance, learning from history matching process and carrying out multiple prediction scenario analysis.

The pilot plan is currently at the early phase of implementation in this field and is considered very important risk mitigation step, towards commercialization of the project. The paper summarized the objectives of the pilot, so that a firm understanding is generated of the expectations and relevance of the pilot in the larger development scheme of the project.

Thermal simulation study results for arriving at the pilot plan would be presented in the paper. How history matching of old CSS pilots and the cold flow data obtained from recent CHOPS pilot wells help in arriving at an improved design of the Steam Flood pilot would be documented.

The contents of the paper can help generating ideas in designing pilots in similar Heavy Oil fields. The document can also serve as a score card for the Lower Fars thermal pilot post implementation, to understand the original objectives of the pilot.
