Dong E&P Company - Literature review Example

The Kolga sands had been remobilized under the burial which led to sand fluidization and injection along weakness zones. On seismic sections, injection wings appeared cross-cutting what surrounded seismic reflection, this was considered as an artifact. They launched the development of the Nini east field in 2009 with a drilling campaign which included two horizontal and one injection in Kolga sand. The main reason for using this kind of approach was to increase the percentage of horizontal section in pay while avoiding the sele shale and maintaining the oil-water contact.

They also decided that it was crucial to get a better handle on seismic data to plan for the two upcoming wells. The seismic data was processed and inverted to improve the imaging of the injectable sands The understanding of the reservoir and its heterogeneity was greatly improved with the use of the new generation deep directional electromagnetic tool which was the LWD and the new processing method. This tool was critical in refining the reservoir model and ultimately for the management of this field in the long term.
