CO2 Research Well

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.
