Patent number: 10961793Abstract: This system maintains bottom hole pressure and constant well bore pressure profile for a period of time in event of loss of power to rig pumps, rig pump failure or other loss of pressure to the primary flowline. The back pressure system diverts mud into the primary flowline to maintain pressure. The system provides time to get the diesel powered cement unit on line to maintain pressure or get the power reinstated to the rig pumps. The mud discharged into the primary flowline can be recovered back into the housing via the housing inlet line and the housing can be recharged via the N2 high pressure bottle rack. The back pressure system installs upstream of the MPD chokes with interfaces to the primary flow line to divert the drilling mud to the primary flowline.Type: GrantFiled: July 10, 2018Date of Patent: March 30, 2021Assignee: PRUITT TOOL & SUPPLY CO.Inventor: Martyn Parker

Patent number: 10954732Abstract: A BHA features an MWD tool connected to a running tool supporting a whipstock that is connected to an open hole anchor. The anchor is flow set and after the anchor is set the running tool collets release from the whipstock to allow cement to be pumped through the anchor to hold the set position. The collets are released from the whipstock also with flow and after the anchor has been set. One way is to use nozzles in series. Another is to run in with a ball on the anchor seat, set the anchor and blow out the ball seat so flow can again be used to release the running tool collets. Another is suspending a ball above the anchor seat, releasing the ball with pressure cycle, open another flow passage to allow collet release of the whipstock. Finally, pressure can be used to release the running tool collets.Type: GrantFiled: August 14, 2018Date of Patent: March 23, 2021Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Gregory L.
