Title: Analyses and applications of pressure, flowrate, and temperature measurements during a perforating run

Perforating technology has undergone significant advances during the last decade. Tubing conveyed perforating (TCP), underbalanced perforating, high shot density guns, better shaped charges, and improved gun systems are some of the developments that have contributed to safer operations and improved productivity of the perforated completions. A recent development, described in this paper, is a perforating tool that makes real-time downhole measurements during a perforating run and has the capability of selectively firing a number of guns at different depths or times. These measurements include pressure, flow rate, temperature, GR, CCL, and cable tension. The simultaneous downhole measurements, in addition to providing better control of the perforating process, can in a single trip provide a production log, conventional well tests before and after perforating, and a fill-up or slug test soon after perforating for underbalanced conditions.
