Abstract (en)
[origin: US2018223607A1] A toe casing is made of a material different from conventional casing, and may be deployed in an open-hole section of a well that is not economically accessible by conventional casing. The toe casing may be made of a material that more easily conforms to the well bore, such as aluminum alloy, titanium alloy, or a composite material. The toe casing may be secured to and deployed at the end of a conventional casing string for the purpose of assisting the casing in reaching a desired depth, allowing for improved hydrocarbon production.
