Abstract

This project targets performance enhancement for gravel pack jobs through integrating a jetting tool with the standard cased hole gravel pack assembly. Through jetting the sump packer bore before stinging in with snap latch or locator seal assemblies, the risk of Pulling out of hole with the screen assembly is reduced and therefore better performance for the gravel packing tool is granted. Jetting the seal bore of the sump packer also helps in reducing the risk of damaging the seals of any seal assembly to be run with the gravel pack assembly. Observing the performance of gravel pack jobs indicates the importance of proper wellbore clean up prior to performing gravel packing. In some cases, and especially in cased hole applications with debris resulting from Tubing Conveyed Perforation (TCP) operations, jetting the seal bore of sump packer will be of added value in terms of increasing the operation efficiency besides reducing the non-productive time NPT that could result from improper wellbore clean up. Conception and design aspects are described in the attached file including: 1) Problem and solution statements 2) Design and engineering drawings for all product components 3) Economic study based on the scope of the project which may be expanded on a much wider scale
