The Letton Hall Group managed six tasks which together mature subsea multiphase metering technology.These tasks involve evaluating the impact of deposition and erosion within the meter, collecting fluid samples passing through a meter, deploying check meter technology and understanding the uncertainty of meter measurements.

Ultra-High Conductivity Umbilicals

2007 Ultra-Deepwater

Project Number: 07121-1302 Project Status: completed
Start Date: Dec. 5, 2008 End Date: May 30, 2010
RPSEA PM: James Pappas Principal Investigator: Dean Hulsey
Subcontractor: NanoRidge Materials, Inc.
Project Objectives:

The goal of this project is to develop an ultra-high conductivity power cable suitable for use in undersea umbilicals. The overall objective is to design, build, and test an engineering prototype of a working ultra-high conductivity cable that could in later stages be incorporated into an umbilical exceeding 100 miles in length and called upon to deliver up to 10 MW at up to 36 kV with operating temperatures up to 250°F and pressures up to 4500 psi.

Start Date: Dec. 15, 2008 End Date: March 16, 2012
RPSEA PM: James Pappas Principal Investigator: Steven Hudak
Subcontractor: Southwest Research Institute
Project Objectives:

High strength riser steels which resist fatigue damage in a sour corrosive environment offer significant weight advantages for deepwater structures. Southwest Research Institute is laboratory testing the compatibility of six high strength materials for their performance in such riser service.

Flow Phenomena in Jumpers-Relation to Hydrate Plugging Risk

2007 Ultra-Deepwater

Project Number: 07121-1603a Project Status: completed
Start Date: Sept. 22, 2008 End Date: March 21, 2010
RPSEA PM: James Pappas Principal Investigator: Michael Volk
Subcontractor: The University of Tulsa
Project Objectives:

To understand the behavior of hydrate formation and transport in subsea jumper configuration during well restart events. This improved understanding will promote development of well start-up procedures which minimize potential hydrate plugs.

Hydrate Plug Characterization and Dissociation Strategies

2007 Ultra-Deepwater

Project Number: 07121-1603b Project Status: completed
Start Date: Sept. 22, 2008 End Date: Sept. 21, 2010
RPSEA PM: James Pappas Principal Investigator: Michael Volk
Subcontractor: The University of Tulsa
Project Objectives:

The University of Tulsa is performing hydrate formation and plug characterization in their unique testing facilities. The data will be used to benchmark predictive models both for the formation of plugs and for their disassociation. This information quickly migrates to the field for application to current needs.

Design Investigation of Extreme High Pressure, High Temperature, (XHPHT), Subsurface Safety Valves (SSSV)

2007 Ultra-Deepwater

Project Number: 07121-1603c Project Status: completed
