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. Giroux, David Shahin, Adrian Vuyk, Jr., Gary Thompson, Kevin Leon Gray, John Timothy Allen, Randy Gene Snider
