Sammendrag
The Gyda field has been on stream since June 1990. Water injection commenced Feb. 1991. Currently Gyda is suffering from high water cuts. Having in mind that water injection is very costly, environmentally pollutant and associates with scale formation problems, the question which arises here is whether water injection (real development scenario of Gyda) was the best choice or not?
This study is not concerning about prediction of future production; rather it is a backward study to see: if we would have implemented other production scenarios, what could be our cumulative productions at present. Alternative production scenarios have been investigated and the results suggest that water injection scenario was indeed the best choice. Further, the real scenario (water injection) has been modified by ESP (Electric Submersible Pump), gas lift, infill drilling and new injectors, which led to 10 MMbbl increase in the historical oil production.
The latest history-matched 2010 Gyda compositional reservoir model was used with Petrel seismic to simulation software, which is served as the front end to the ECLIPSE reservoir simulation software.
