Geosteering with Azimuthal Resistivity Tool in Thin Oil Rim Horizontal Well - A Case Study from the Malay Basin

The application of Azimuthal Resistivity tool has been used in 2 fields operated by Newfield Peninsula Malaysia in the Malay basin. To-date a total of 27 horizontal wells have been drilled with azimuthal resistivity tool. The expectation is that the tool provides key information on fluid and/or structural boundaries that helps to improve the trajectory of the horizontal section of the wells. The key drivers are to stay at certain elevation above oil-water contact while maximising net pay. The tool is capable to look deeper into the rock formation giving estimation of distance to fluid or lithological boundaries. This paper explains the successfully application of azimuthal resistivity tool and how this geosteering technology has benefited Newfield in meeting its reservoir targets
