US Patent:

6779604, Aug 24, 2004

Filed:

May 21, 2001

Appl. No.:

09/862795

Inventors:

Mark W. Biegler - Houston TX
John W. Mohr - Missouri City TX
Roger A. Frederickson - Meraux LA

Assignee:

ExxonMobil Upstream Research Company - Houston TX

International Classification:

E21B 4304

US Classification:

166278, 166228

Abstract:

A gravel pack is formed using a mixture of a solid deformable material and conventional gravel pack gravel. In the event of reservoir compaction, such a gravel pack will reduce the transmission of forces from the subterranean formation to the wellbore completion hardware, thereby significantly extending the life of a well. Deformable materials selected for mixing with conventional gravel may be elastically flexible, plastically deformable, or crushable solid materials or particles.

Abstract:

A method associated with the selection of tubulars for hydrocarbon production is described based upon evaluating the performance limits of threaded connections. Constituents of an evaluation group of threaded connections are determined and then a first group of the connections is evaluated via model analysis over a range of conditions. Then, physical testing on a first group of threaded connections in the evaluation group is conducted over that range of conditions. Once modeled, the results from the physical testing and the modeling analysis of the first group are compared to assess a characteristic performance factor for the first group. A second group of threaded connections are determined and the assessed performance factor from the first group is applied to a second group, and the performance limits of the second group are defined over the range of conditions based on this characteristic performance factor, without requiring testing the second group.
