Washington, DC — Thirteen projects aimed at reducing the risks while enhancing the environmental performance of drilling for natural gas and oil in ultra-deepwater settings have been selected by the U.S. Department of Energy (DOE) for further development.
Negotiations for the new projects will lead to awards totaling $35.4 million, adding to the research portfolio of the Office of Fossil Energy’s Ultra-Deepwater and Unconventional Natural Gas and Other Petroleum Resources Program.
Research needs addressed by the projects include (1) new and better ways to monitor displacement during casing cementing using intelligent casing and smart materials, and (2)assessing corrosion, stress cracking, and scale at extreme temperature and pressure. All of the projects aim to develop and validate new technologies to enhance safety and environmental sustainability.
The total value of the projects is more than $56 million over 4 years with approximately $21.2 million of cost-share provided by the research partners in addition to the $35.4 million in federal funds. The research contracts will be administered by the Research Partnership to Secure Energy for America, under the management of the Office of Fossil Energy’s National Energy Technology Laboratory. Brief descriptions of the selected projects follow:
- The Board of Regents of the University of Oklahoma (Norman, Oklahoma) — Intelligent Casing-Intelligent Formation Telemetry System. Researchers at the University of Oklahoma will identify reliable technologies that may be applied to make production casing - the piping that carries oil and gas - "intelligent," allow safe and effective deployment, and ensure highly reliable and effective data transmission to the surface. Much more data from the reservoir could be transmitted to surface operations as a result of this work. Allowing data related to the cementing of the production-casing in the wellbore to be transmitted to the surface in real time would provide personnel with up-to-the-second information, resulting in early identification of any potential incidents.

- GE Global Research (Niskayuna, New York) — All Electric Subsea Autonomous High Integrity Pressure Protection System (HIPPS) Architecture. The goal of this project is to reduce the risk of environmental impacts resulting from subsea equipment failure through the use of improved failsafe systems and controls. An electric failsafe HIPPS will help ensure the integrity and safety of any subsea equipment not rated for the wellhead shut-in pressure. This research addresses the heart of safety, integrity, and reliability of practical subsea facilities. Successful commercialization and utilization of this type of system will result in an added barrier to avoid environmental problems downstream of the system.

- GE Global Research (Niskayuna, New York) — Qualification of Flexible Fiber Reinforced Pipe for 10,000-Foot Water Depths. The goal of this project is to design concepts for light-weight, flexible risers that allow for safe installation, will be capable of faster and easier repair than conventional risers, provide a stronger product that is less apt to rupture, and can potentially resolve situations before they develop into environmental problems. The project will also include prototype manufacturing and qualification testing. The successful development of durable, lower-weight flexible riser technology with low intervention costs and greater than 3,000-meter water depth capability is a key enabling technology for future ultra-deepwater Gulf of Mexico production. DOE share: $7,105,948; Recipient share: $6,331,586; Duration: 4 years
- NanoRidge Materials (Houston, Texas) — Ultra-High Conductivity Umbilicals: Polymer Nanotube Umbilicals. The next step in this continuation project is to achieve a conductivity capability for subsea umbilicals that is at least comparable to that of copper, but at a much lower weight. A polymer nanotube-based high conductivity wire for umbilicals, the cables that provide power to satellite wells, will increase the distance that satellite wells can be located away from surface facilities, leading to a reduction in energy requirements and a smaller operations carbon footprint. Ultimately, the reduced size and weight of the umbilicals will result in easier and potentially safer handling of cable during installation. It will also decrease the need to build and use hubs and platforms, since more efficient power transmission will allow for a subsea option as opposed to a platform option in some cases. The successful application of this technology should be able to be extended onshore, resulting in added efficiency and less stress on onshore power grids. DOE share: $2,558,549; Recipient share: $639,639; Duration: 3 years
- Remora Technology (Houston, Texas) — Deepwater Direct Offloading Systems, Phase 1. The goals of this project are to develop a system-level qualitative assessment of a safe, novel offloading system to enable offloading directly to a tanker from a floating production, storage, and offloading unit, to perform a technology readiness level analysis, and to identify opportunities to pilot the technology. This work will result in a near-field-ready ultra-deepwater direct offloading system that minimizes the amount of required equipment and leak paths, resulting in safer and simpler offloading methods. If developed, the system will allow marine hydrocarbon transfer operations at a level of safety equal to or better than existing systems.
DOE share: $758,255; Recipient share: $400,000; Duration: 1 year

The project will include full-scale lab-strength testing, bench-scale soil ingression, cyclic wear testing, and residual break-strength testing, as well as submerged-rope soil ingression field tests. The researchers will seek to understand all of the potential rope failure modes and their contributing factors to improve the reliability of synthetic mooring systems. The project will reduce the risk of permanent synthetic mooring system failure by determining if seafloor contact impacts the integrity of the ropes.
