Net Sand Determination / Facies Modeling for Development Geological Study

The Lirik Field is located in Japura Block, Central Sumatra Basin, about 145 km to the southeast of Pekanbaru, and about 195 km northwest of Jambi. Geologically the Lirik Field is part of the Japura complex structure. This field was discovered in 1972 and by the end of year 2006, the cumulative oil production reached 40 MMBO and the remaining reserve is about 5 MMBO respectively. Some efforts to optimize the existing production have encountered some problems such as: high water cut and sand distribution. The aim of this paper is to share how to solve the sand distribution problems in this area by using 3-D Application Modeling software.
