Welcome to RPSEA Project 4304 - More Improvements to Deepwater Subsea Measurement.

This project, sponsored by the Research Partnership to Secure Energy for America (RPSEA) and the U.S. Department of Energy, is a follow on to conclude the work begun in RPSEA Project 07121-1301. To close critical gaps in deepwater measurement, the technologies, architectures, and methods developed and enhanced in this follow-on project will advance the ability to protect our people and our environment as we progressively develop deepwater hydrocarbon resources.

RPSEA is a non-profit corporation formed by a consortium of premier U.S. energy research universities, industry and independent research organizations. RPSEA’s mission is to provide a stewardship role in ensuring the focused research, development and deployment of safe, environmentally sensitive technology that can effectively deliver hydrocarbons from domestic resources to the citizens of the United States.

RPSEA is a public benefit research program formed to identify and develop new methods and systems for exploring, producing, and transporting-to-market energy, or energy-derived products. The Energy Policy Act of 2005 established a natural gas supply research and development program to be funded over 10 years. As the consortium chosen to manage these funds, RPSEA will focus its experience, expertise, and capabilities on meeting the program's objectives: to maximize the value of domestic natural gas and oil resources through new technologies, to increase production, and to do so in less expensive, safer and more efficient and environmentally benign ways.

The Letton-Hall Group, LLC (LHG) is the principle contractor for this project. LHG hasparticipated in the advancement of Ultra Deepwater (UDW) measurement technology for over a decade, and brings over 300 years of total experience in measurement technology development and application. Early LHG experiences in the Canyon Express development led to the identification of multiphase measurement technology gaps addressed in Deepstar, which helped define the requirements for RPSEA Project 07121-1301.

The objective of the project is to reliably and economically identify and assess flow and well production or well control events and conditions for the purpose of preparing the appropriate response actions. The project builds on the work accomplished in RPSEA 07121-1301, concluding critical research needed to close key measurement gaps. The project puts emphasis on the development of techniques and methods that reduce the risk of uncontrolled fluid emissions from subsea equipment, such as blowout preventers, wellheads and Christmas trees, and risers and flowlines.
