Application of residual oil saturation logging data in Yakela Condensate Gas Field

The Yakela Condensate Gas Field has been developed from 2005 and been keeping stable production for 10 years until now. It has already entered the middle-late period of development. Residual oil saturation logging has been conducted in several wells in order to monitor residual oil situation accurately, and to guide gas field adjustment. Meanwhile, the authors made an evaluation of reservoir connectivity and assisted to make a fine division of small layers by applying residual oil saturation logging data.
