Abstract:
Thermal methods are the most commonly used Enhanced Oil Recovery methods around the world, one of them is the cyclic steam stimulationprocess, which had been implemented in Bamboo Main field namely the well BB-22.After the execution the well had low oil rate and high water production occurred.
In this thesis,detail analysis and evaluation has been done to determine the main reason of high the water cut which raised up to 98 % in well BB-22, it has been found that the steam distribution in the layers is not as same as designed.
In order to solve this problem it’s highly recommended to close the lower layer and redesign the optimum injection parameters for the upper lower (i.e.Steam Quality, injection rate,steam Temperature) for a new cycle using Computer Modeling Group (CMG) software.
From the results obtained after redesigning, it has been found that the oil rate increases four times, and the water cut decreases from 98% to 33%.
