Patent number: 10718172Abstract: A method for monitoring a well bore during drilling operations, particularly with respect to a fluid gain and/or fluid loss event. Monitoring the well bore may be accomplished by monitoring an incoming flow rate of the fluid into the wellbore. The fluid return line from the well bore may carry drilling fluid from the well bore to a mud gas separator located downstream from the well bore. Changes in at least one parameter of the mud gas separator may be monitored. The changes to the at least one parameter of a mud gas separator may be compared to the incoming flow rate of the fluid. Discrepancies between the changes and the incoming flow rate may be indicative of a fluid gain or fluid loss condition.Type: GrantFiled: June 27, 2016Date of Patent: July 21, 2020Assignee: Schlumberger Technology CorporationInventors: Paul Andrew Thow, Yawan Couturier

Patent number: 10683715Abstract: A system includes a mud pump for pumping a drilling mud from a drilling mud source, through a drill string, out a drill bit and into an annular, and a plurality of chokes disposed down stream from the mud pump, including a first choke disposed between the mud pump and the drill string, and a second choke disposed between the mud pump and a mud tank. The system further includes a fluid discharge conduit in fluid communication with the annular space for transferring the drilling mud to handling equipment in fluid communication with the mud tank. The first choke receives the drilling mud from the mud pump at a first flow rate, the first choke reduces drilling mud flow rate to a second flow rate less than the first flow rate, and the second choke reduces drilling mud flow rate to a third flow rate.Type: GrantFiled: August 29, 2016Date of Patent: June 16, 2020Assignee: Schlumberger Technology CorporationInventors: Yawan Couturier, Paul Andrew Thow, Blaine Dow, Jesse Alan Hardt

Patent number: 10648315Abstract: A method includes pumping fluid into a drill string extending through a riser into a well. A managed pressure drilling system is operated to maintain a selected fluid pressure in the well between the well and the drill string. A fluid influx into the well or a fluid loss into a formation traversed by the well is detected using measurements of fluid pressure in the well and fluid flow into and out of the well. The method includes automatically abating the fluid influx by closing an annular blowout preventer disposed in the riser or abating the fluid loss by operating the annular blowout preventer and pumping a sacrificial fluid into the drill string.Type: GrantFiled: June 29, 2016Date of Patent: May 12, 2020Assignee: Schlumberger Technology CorporationInventors: Yawan Couturier, Bastiaan Liezenberg, Glenn Johnson, Vikas Rakhunde, Jesse Hardt

Patent number: 10132129Abstract: A method for maintaining pressure in a wellbore drilled from a drilling platform floating on a body of water includes the steps of pumping fluid at a determined flow rate into a drill string disposed in a wellbore and measuring fluid pressure within a fluid discharge line of fluid returning from the wellbore. The fluid discharge line has a variable length corresponding to an elevation of the floating platform above the bottom of the body of water. The wellbore pressure is determined at a selected depth in the wellbore or at a selected position along a drilling riser or variable length portion of the fluid discharge line using known parameters/methods. The determined wellbore pressure is adjusted for changes in length of the fluid discharge line corresponding to changes in the elevation of the floating platform relative to the bottom of the body of water.Type: GrantFiled: August 9, 2016Date of Patent: November 20, 2018Assignee: Smith International, Inc.Inventors: Donald G.

Publication number: 20170037690Abstract: A method for responding to an adverse fluid event such as a fluid gain or fluid loss event includes pumping a drilling fluid through a drilling system having a drill string and into a well bore. The drilling system also includes at least two pressure control components operatively coupled to the drill string. The bottom hole pressure of the well bore may be monitored. Once a fluid loss condition or a fluid gain condition is detected, a response for each of the at least two pressure control components to the fluid loss or fluid gain condition is determined.
