Tight carbonate gas reservoirs require stimulation in order to establish commercial viability. In order for the development plan to be considered effective and successful, two main parameters have to be studied and evaluated, time, and cost. The conventional method to stimulate tight carbonate reservoirs is bull heading acid fracturing treatment, which is costly and time consuming for multi stages wells, not excluding the high treatment pressure requirement and risk associated with it. Conventional plug and perf technique includes e-line operations to perforate with guns, acid fracturing treatment by bullheading, and e-line operations to set plugs for every single stage.
A novel acid-soluble abrasive material, was implanted and tested as an economical and time effective alternative solution. The technique involves perforating through cemented liners utilizing the abrasive material flowed by low volume acid surgesqueeze. By using this technique time and cost associated with the conventional plug and perf technique, can be reduced and achieve even better result with less cost and time.
The wells that were stimulated with this technique, were tested and proven superior in terms of production rate over the conventional plug and perf technique in the short term. More evaluation to be done on the wells over the long term and evaluate if they are going to sustain the production over time.
This paper provides a brief summary about the technique. Also, will discuss in details, the cost and time effectiveness, the short term result, and compare it with the conventional plug and perf technique.
