2009 Projects Identified

Four projects were totaling $286,478 were recommended for co-funding at the 2008 GSTC Fall Meeting in October 2008. The funding cycle for these projects will be January 1, 2009 to December 31, 2009. The GSTC has approved over $2.8 million to co-fund 23 projects since inception in June 2004. The new projects are:

The executive summaries for these projects are available on the GSTC website.

 

GSTC Executive Council

The GSTC welcomes the four new Executive Council members that have been elected to serve for 2009-2010:

  • Gerald Han, Atmos Energy
  • Chuck Weinstein, NITEC, LLC
  • Clayton Roth, NW Natural
  • Doug Elenbaas, TransCanada Pipeline

The members will join the council members who will continue to serve until the end of 2009.

  • Larry Kennedy, El Paso
  • Brian Hall, Equitable Resources
  • Ray Harris, National Fuel
  • Steve Bergin, ONEOK, Inc.

 

New NETL Project Manager Named

Mr. Keith Dodrill, General Engineer Energy Infrastructure Team, NETL, assumed the duties as the NETL Project Manager for the GSTC in October 2008. Mr. Dodrill replaces Mr. Richard Baker, Project Manager and Methane Hydrate program Team Lead in the Natural Gas and Oil Technology Management Division of the Strategic Center for Natural Gas and Oil at NETL.

 

Effects of Tensile Loading on the Remaining Strength of Corroded Casing Final Report

The final report for the 2006 project, Effects of Tensile Loading on the Remaining Strength of Corroded Casing, (Kiefner and Associates) has been posted to the GSTC member’s only section of the website. The project examined two issues that need to be addressed if the ability to evaluate metal-loss defects in borehole casing and tubings is to keep pace with the new generation logging tools. First, the database used to validate any new criterion for borehole casing and tubing to be extended to incorporate tests that include axial loading and internal pressure. Second, a new criterion for the evaluation of metal loss in casings and tubing that incorporates the actual stress applied to these components. The report outlines the test program undertaken to develop the required database and the development of a criterion for corroded casings with combined internal pressure and axial loading. The period of performance for this project was June 1, 2006 – June 30, 2008.

 

2006 Final Reports Distributed
