Abstract

A rotating check valve is disclosed for improved debris collection within a wellbore. The check valve can be part of a debris removal tool that includes a motor, pump, gearbox, bailer, milling bit, the check valve, rotational shafts. On its uphole end, the check valve can be coupled with the bailer such that the check valve can rotate relative to the bailer. Also on the uphole end, the check valve can be rotationally coupled to a shaft that passes through the bailer and couples with the gearbox. On the downhole end, the check valve can be rotationally coupled to the milling bit. The check valve can include a torque transfer mechanism that transfers torque generated by the motor and gearbox to the milling bit. The check valve can include a unidirectional flow control mechanism that restricts the flow of fluid and debris to the uphole direction.
