ABSTRACT:
The steel drill string attached to a drilling bit during typical rotary drilling operations used to drill oil and gas wells is used for the second purpose as the casing that is permanently installed in the wellbore for the final completion of oil and gas wells. The rotary drill bit is attached to the drill string, the well drilled, and the well is completed leaving the drill bit attached to the drill string to make a steel cased well. The steel coiled tubing attached to a coiled tubing conveyed mud motor driven rotary drill bit is used to drill oil and gas wells that is used for a second purpose as the tubing that is permanently installed in the wellbore to make a tubing encased well for the final completion of oil and gas wells. The mud motor driven rotary drill bit is attached to the coiled tubing, the well is drilled with said tubing conveyed mud motor driven rotary drill bit, and the well is completed leaving the mud motor driven rotary drill bit attached to the coiled tubing to make a tubing encased well. Various different types of slurry materials are used for well completion that include cement, gravel, water, a "cement clinker", any "blast furnace slag mixture", or any other suitable substance that flows under sufficient pressure. Such slurry mixtures are used to complete wells including at least the following: open-hole well completions; typical cemented well completions having a perforated casing; gravel well completions having perforated casings; extended reach wellbores; and extended reach lateral wellbores as typically completed from offshore drilling platforms.
