Tubing-conveyed perforating; Operating experience

Abstract

In 1981, the authors utilized tubing conveyed perforating (TCP) as a perforating technique in its well completions. This paper draws conclusions on the benefits of utilizing a TCP technique as opposed to wireline perforating techniques. Based on the operating experience gained on a sample of some 75 TCP jobs, only less than 10 percent can be considered failures. The results achieved with varying amounts of underbalance are compared with published results. Although advantages can be gained with the TCP technique, it is only as successful as the weakest link will allow, in the chain of events leading to the final completion. Therefore, the application of TCP should be considered as a component part of an effective completion program.
