Research Well No. 3

Why CO2?

Geologic sequestration of CO2 (meaning the injection and long-term storage of CO2 deep in the subsurface) is one of many tools that are needed to reduce CO2 emissions into the atmosphere. This process is commonly termed Carbon Capture and Sequestration, or CCS. Louisiana is one of the best locations in the US to implement industrial-scale CCS because of its subsurface geology, large point-source emissions from industry to capture CO2, a pipeline network for transportation, and a highly experienced workforce. The LSU CO2 research well will help answer questions and advance technology related to CO2 sequestration, as we have done for many decades for oil-and-gas-related research, training, testing, and education.

Funding

The project is funded by the EDA through a grant from H2theFuture, which includes a match from Louisiana Economic Development. Funds have also been provided through an appropriation from the State of Louisiana. Additionally, significant corporate partnerships are being developed, allowing for a more ambitious project than what could have been done with the project funding alone. See the Corporate Partners link for more details.

Well Description

While extensive details will continue to be posted under the Technical Details section, these are the essentials: the well is a wellbore only, cased and cemented but without fluid communication to the subsurface. The completions inside the wellbore allow fluid circulation and measurement in ways that can mimic many of the processes in actual injection or production wells. The new well will have a large-diameter (13-3/8”) vertical section to a depth of 5,000 ft. and transition to medium diameter (9-5/8”) below that depth. At 7,000 ft., it will deviate from vertical and transition to a horizontal section that will land at approximately 7,900 ft.-vertical-depth and extend for 500-1,000 ft. laterally. The completions inside the wellbore will be made of corrosion-resistant alloy, enabling the use of CO2 without risking corrosion. The well will contain a variety of instrumentation, including multiple fiber-optic strings.

Timeline

Well design occurred during mid-2024, and project planning is happening during the fall of 2024. Drilling is planned for 2025, although the exact dates are not known, pending various approvals and the availability of rigs.

Research, Testing, and Training

As with the rest of the PERTT Lab, the new well and associated flowloop will be available for research, testing, training, and education. Research is usually conducted in partnership with LSU faculty. Facility use can be contracted directly with the PERTT Lab. Training and testing opportunities are designed on case-by-case basis, depending on the needs of the customer and capabilities of the lab. Contact either the PERTT Lab or the Craft & Hawkins Department of Petroleum Engineering for more information.

The new well will have a 5,000-ft. vertical section with a 13 3/8-inch-thick diameter casing, transitioning to 9-5/8-inch diameter below 5,000 ft.  At 7,000 ft vertical depth the well will deviate from vertical at approximately 6 degrees/100 ft in a northeast direction. It will land with a horizontal section (500 to 1000 ft) at approximately 7,900-ft. vertical depth, which is in the Anahuac formation. Total measured depth will be between 9,000-10,000 ft.

Like existing wells at the PERTT Lab, the new well will be cemented and cased but without communication into the subsurface. As such, these wells are designed for research on wellbore fluid mechanics; testing of downhole tools/technology; and simulating injection/production operations for the purpose of training, testing, or research. The outer casings will be traditional carbon steel, with inner completions made from corrosion-resistant alloy (CRA) that allows circulation of CO2 in all phases and with a variety of compositions that may be relevant to field operations.

The initial CRA completion will sit inside the large-diameter 5,000-ft. vertical section, constructed with a combination of 7 5/8-inch casing and 2 7/8-inch tubing. Valves, chokes, instrumentation, and fiber will enable the variety of flow scenarios and measurements needed for the initial projects. This inner-completion design will help limit construction costs, as well as limit the volumes and rates for fluid injection for the first research projects. Future completions would take advantage of the deviated part of the wellbore as research or testing needs dictate.

The well will have multiple fiber-optic lines (covering different parts of the completions and different depths), as well as traditional instrumentation. Surface facilities for fluid storage, compression, pumping, and separation are still being planned.

While the project is funded by the Economic Development Administration and Louisiana Economic Development (with additional direct state funding), we have been able to plan a much more ambitious project because of the generous partnerships and contributions of our corporate sponsors.
