Two-stepping horizontal well production: A new dual gas-lift system energizes well flow vertically and laterally

摘要

If necessity is the mother of invention, then persistence is what feeds the inventor's soul. The trial-and-error nature of the discovery process eventually ends with a "eureka!" moment. For Bill Quinlan, a professional engineer with Horizontal Lift Technologies, that moment came while at work in a tight formation development. "The idea for the dual gas-lift system came from a horizontal well development that we drilled in Michigan," Quinlan said. "We drilled several 4,000-ft [1,219-m] laterals to open a fairly tight dolomite formation enough to make production economically feasible."
