Patent number: 10378307Abstract: A layer of permeable material is positioned on an area of lost circulation lithology in a wellbore. An example of the permeable material includes a planar member with perforations that is rolled into and retained in an annular configuration. The permeable material is lowered into the wellbore adjacent the area of lost circulation and allowed to unroll and expand radially outward against walls of the wellbore. The wellbore wall along the area of lost circulation lithology can be reamed out so the layer of permeable material is out of the way of a drill bit. Applying a bridging agent on the interface where the permeable material contacts the wellbore wall forms a flow barrier.Type: GrantFiled: April 18, 2018Date of Patent: August 13, 2019Assignee: Saudi Arabian Oil CompanyInventors: John Timothy Allen, Brett Bouldin

Publication number: 20150240614Abstract: A method for performing a seismic investigation during subterranean drilling operations includes connecting a bottom hole assembly to a drill string. The bottom hole assembly includes a drill bit and a vibration damper. The drill string is lowered into a borehole and rotated to drill the borehole to a greater length with the drill bit. An actual vibration generated by the bottom hole assembly is measured with a control system and the actual vibration is compared to a target seismic vibration range. When the actual vibration is outside of the target seismic vibration range, the dampening coefficient of the vibration damper is changed.Type: ApplicationFiled: February 17, 2015Publication date: August 27, 2015Inventors: John Timothy Allen, Michael Anthony Jervis

Patent number: 7654325Abstract: The present invention provides a method and apparatus for handling tubulars and drilling with tubulars such as casing into a formation. In one aspect of the invention, the apparatus comprises a circulating head and a cementing head operatively connectible to a gripping member. The circulating head is used to circulate drilling fluid while drilling with casing, and the cementing head is used to cement the casing string within the formation at a desired depth. The present invention also relates to methods and apparatus for isolating a tensile load from a drilling apparatus rotated by a top drive. In one aspect, the present invention provides a load isolator apparatus having an isolator body operatively connected to the top drive and a torque body at least partially disposed in the isolator body. In operation, the bearing assembly transfers the tensile load from the torque body to the isolator body.Type: GrantFiled: October 31, 2007Date of Patent: February 2, 2010Assignee: Weatherford/Lamb, Inc.Inventors: Richard L.
