RPSEA members provided more » hundreds of subject matter experts who contributed thousands of hours in directing this program, as is evident by results described in this report documenting a most successful public private partnership. It also includes a summary of technology transfer efforts, which have reached a worldwide audience, resulting in accelerated and highly successful implementations of newly developed technologies. This Final Report briefly describes each of the program elements and includes descriptions of specific projects that illustrate successful technology development efforts funded through the program. This Final Report covers the period from 2007, when research began, through 2016, when the program ended, and builds a foundation for work that can be conducted in the future. Department of Energy (DOE), through its National Energy Technology Laboratory (NETL), implemented a non-duplicative research and development (R&D) program to complement the RPSEA administered program elements. RPSEA administered three of the four program elements identified in EPAct, pursuant to Annual Plans, which included: ultra-deepwater architecture and technology, unconventional natural gas and other petroleum resources exploration and production technology, and technology challenges of small producers. This document is the Research Partnership to Secure Energy for America (RPSEA) Final Report for the Ultra-Deepwater and Unconventional Natural Gas and Other Petroleum Resources Research and Development Program (Program) established pursuant to Title IX, Subtitle J, Section 999 (Section 999), of the Energy Policy Act of 2005 (EPAct).
