Abstract
We found out gas is producing from the beginning section of open hole interval. We recognized this happened after increasing the wellhead choke size in order to increase oil production without bearing in mind that the field is natural fracture carbonate reservoir which has very large numbers of vertical and horizontal fractures in reservoir rock. Also in spite of starting gas injection project, pressure drop continued to increase as a result of increasing oil production rate which caused more oil loss. Consequently gas oil contact has gone down and we had additional gas production in our producing wells.
