Re-Development of a Mature FieldFor Production Acceleration, Intisar 103E Field

This paper presents a successful re-development and production acceleration project of Intisar E Field, Upper Girs A, B and C reservoirs of the Zueitina Oil Company. The project was implemented from 1999 to 2002 on the bases of a reservoir simulation study. The re-development plan comprised drilling 6 vertical injectors and 6 horizontal producers, and re-completion of existing 8 wells as commingled and/or dual producers. As a result of this project, the oil production potential of Upper Gir reservoirs has been increased almost by three folds from an average of 6,400 STB/D in 1999 to 20,000 STB/D in September 2002. The incremental reserves are predicted at 33.4 MMSTB until the year 2022.
