Application of geosteering technique in Assel-15H horizontal well

Using the geosteering technology in Sudan oilfields can break the western technology monopoly and solve the technology challenge during the horizontal well drilling process. This article uses Assel-15H as an example, carrying out pre-drilling geological risk analysis. Combined the 3-D geological modeling and the oriented geosteering technology, making full use of the LWD data and rebuilding the 3D geological model during the drilling process, a high drilling footage has been finally achieved. The success of this horizontal well gives a reference on how to use the geosteering technique in the complex fault block reservoir and how to make the proposed solutions in the horizontal well drilling.
