Abstract

Due to the non-defined contouring of the Bunjani field and the positive exploration well Jo-2 at the southwest of the field outside the concession, a need for the geological reinterpretation of the area wasdiscovered in order to solve the petroleum-geological relationships inthe arcea, and determine field expansion and reservoir contouring in amore qualitative way. The recent geological reinterpretation was performed on the basis of a review of all available data from the existingwells, the results of field development to the present , the interprttation of new seismic profiles and the knowledge of the petroleum-geological relationships in the part of the basin previously acquired. The reinterpretation proved to be justified and it resulted in the determination of new well locations and their drilling in 1993 and 1994. In this way, the field expanded towards the southwest and the north. With the new reservoir geometry, better quality data of the reservoir characteristics, analyses obtained from the new wells, together with the reinterpretation of electric log analyses obtained from old wells, the reserves of oil have been increased by 31.4%.
