Abstract

Mishrif Formation is the main reservoir in Amara Oil Field. It is divided into three units (MA, TZ1, and MB12). Geological model is important to build reservoir model that was built by Petrel -2009. FZI method was used to determine relationship between porosity and permeability for core data and permeability values for the uncored interval for Mishrif formation. A reservoir simulation model was adopted in this study using Eclipse 100. In this model, production history matching executed by production data for (AM1, AM4) wells since 2001 to 2015. Four different prediction cases have been suggested in the future performance of Mishrif reservoir for ten years extending from June 2015 to June 2025. The comparison has been made between these different cases to select the best case for developing the field that gives the highest recovery factor. The case-4 was chosen to be the best case involved adding 20 vertical production wells, 5 horizontal production wells and 5 vertical injection wells in the reservoir with plateau rate of 50MSTB/D in starting of prediction and dropping to reach 13.5 MSTB/D in end of the prediction and the cumulative production from the reservoir equal to 82 MMSTB and recovery factor reaching 9.06% at the end of 2025.
