Abstract
A jet pump reamer/stabilizer drilling assembly is used during the underbalanced or near-balanced drilling of an oil, gas, geothermal, or sequestration well or disposal reservoir to create a low pressure zone around the drill bit. The design of this jet pump drilling reamer/stabilizer assembly limits the flow of drilling/power fluid through the drill bit. The drilling fluid circulation behind the drill bit is a conventional flow down the drill pipe and back up through the annulus. The drilling fluid circulation around and up through the drill bit is reverse circulation.
