Incorporating sequence stratigraphy in reservoir simulation: an integrated study of the meren E-01/MR-05 sands in the niger delta

摘要

The Meren oil field is located offshore Nigeria, about 110 miles south-east of Lagos. The reservoir consists of interstratified sandstones and shales, mostly representing shoreface to shelf deposition. The E-01/MR-05 reservoir, one of the most prolific intervals in the Niger Delta, was placed on production in 1968. The field was shut-in in 1985 due to declining pressure and production, and was brought back on production in 1989. In 1991, a waterflood was initiated. Although the waterflood was successful on an overall basis, limited response was observed in some of the reservoir units due to preferential movement of the water bank. To improve the waterflood conformance and thus the recovery, an integrated study of the E-01/MR-05 reservoir was proposed.
