Appl. No.:

13/304075

Inventors:

John RODGERS - Roanoke TX, US

Cam LE - Houston TX, US

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - Houston TX

International Classification:

E21B 47/12

US Classification:

166 66

Abstract:

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.

Abstract:

A method of utilizing a shock model for prediction of perforating effects can include recording measurements of the perforating effects on an actual perforating string in a wellbore, adjusting the shock model so that predictions of the perforating effects output by the shock model substantially match the measurements of the perforating effects, and causing the adjusted shock model to predict the perforating effects for a proposed perforating string. A method of predicting perforating effects on a perforating string in a wellbore can include inputting a three dimensional well model and a three dimensional model of the perforating string into a shock model, and causing the shock model to predict the perforating effects on the perforating string.
