Abstract

Official abstract text for this publication.

A shock sensing tool for use with well perforating can include a generally tubular structure which is fluid pressure balanced, at least one strain sensor which senses strain in the structure, and a pressure sensor which senses pressure external to the structure. A well system can include a perforating string including multiple perforating guns and at least one shock sensing tool, with the shock sensing tool being interconnected in the perforating string between one of the perforating guns and at least one of: a) another of the perforating guns, and b) a firing head.

First claim

Opening claim text (preview).

What is claimed is: 1. A well system, comprising: a perforating string including multiple perforating guns and at least one shock sensing tool which measures shock experienced by the perforating string due to detonation of the perforating guns and which stores within the shock sensing tool at least one measurement of the shock, wherein the shock sensing tool is interconnected in the perforating string between a firing head and a perforating gun nearest the firing head, wherein t…
