Patent number: 9494000Abstract: This Application addresses maintaining a hydrostatic pressure exerted on a wall of a wellbore in different intervals of the wellbore. This is done by flowing a liquid through at least a pressure regulator in each interval, and wherein each pressure regulators regulates the amount of pressure exerted by the liquid on the wall of the wellbore. The amount of pressure may be maintained for a specific period of time. The wellbore is part of a soft subterranean formation.Type: GrantFiled: February 3, 2011Date of Patent: November 15, 2016Assignee: Halliburton Energy Services, Inc.Inventors: Tommy Frank Grigsby, Bruce Techentien

Patent number: 7108083Abstract: An apparatus and method for completing an interval of a wellbore while drilling comprises a drill string (52) having a drill bit (30) mounted on the lower end thereof. A completion assembly (50) is positioned around a section of the drill string (52) such that when the wellbore (32) is extended by rotating the drill bit (30) and advancing the drill string (52), the completion assembly (50) does not rotate. The advancement of the drill string (52) and rotation of the drill bit (30) is ceased when the completion assembly (50) has reached the desired interval of the wellbore (32). Thereafter, the drill string (52) is disconnected from the drill bit (30) for retrieval to the surface leaving the completion assembly (50) and the drill bit (30) downhole.Type: GrantFiled: December 3, 2003Date of Patent: September 19, 2006Assignee: Halliburton Energy Services, Inc.Inventors: Floyd Randolph Simonds, Morris Wayne Cox, Terry Michael Dailey, Tommie Austin Freeman, Jiten Chatterji, R.
