Abstract :
Excessive water production is one of the major problems in oil industry, which comes with a lot of challenges; the biggest one is defining the total recovery drop caused by the water production. As mentioned the case study below Aswad field has high oil potential but due to highly water cut production the reserve reduced as estimated, using Excel sheet and decline curve analysis DCA method, the amount of ultimate reserve that could be extracted from the Aswad field is 37.7 MMSTB with recovery factor 39.15 %,this data from the company estimate reserve, and from this project analysis using DCA, the type of the DCA curve used has been chosen depending on the value of the decline exponent constant (b) watch is based on the production data and the behavior of nominal decline rate varies with rate and the error analysis, the value of (b) is one (Harmonic Decline Type). The ultimate reserve that could be generated under current reservoir conditions calculated as 32.88 MMSTB, this value indicates a decrease in field productivity due to high water production problems because multilayer channeling, which means that the field needs to optimize and reduce the water rate as fast as possible to reduce the losses in the recovery that would happen.
