Analyses and Applications of Pressure, Flow Rate, and Temperature Measurements During a Perforating Run

Abstract

Development of a perforating tool making real-time downhole measurements during a perforating run, able to fire a number of guns at different depths or times. In addition to providing better control of the perforating process, the simultaneous downhole measurements can provide in a single trip a production log, conventional well tests before and after perforating, and a fill-up or slug test soon after perforating for underbalanced conditions. The completion can thus be evaluated in real time and any needed remedial reperforating can be performed while the gun is still in the hole.
