Patent number: 6454012Abstract: An apparatus and method for absorbing shock downhole in a wellbore. The kinetic energy from a moving tool is absorbed to dissipate such energy, to decelerate the moving tool, or to prevent impact damage s from contact between the tool and other downhole components. An actuator has an interference fit with a body such as the interior wall of a tubing section. When the moving tool actuates the actuator to move the actuator relative to the body, kinetic energy is dissipated into the body as the body elastically deforms due to the moving actuator. The amount of energy dissipated can be determined from the strength of the body, the contact dimensions between the actuator and body, and the length of moving contact between the actuator and body.Type: GrantFiled: June 8, 2000Date of Patent: September 24, 2002Assignee: Halliburton Energy Services, Inc.Inventor: Michael Reid

Patent number: 6419018Abstract: A subsea subterranean well completion has a tubing string with a portion that extends through a region of the completion exposed to temperatures sufficiently low to potentially create wax and/or hydrate deposits within the tubing string during pre-production or shut-down periods. In order to inhibit or remove the formation of these deposits, the well completion is provided with a flow assurance system operative to create a flow of heating fluid which is recirculated through the space between the tubing string portion and the well casing/production riser structure in a manner causing the heating fluid to flow along the outer side of the tubing string portion without previously or subsequently traversing the interior of the tubing string. The heat absorbed by the tubing string inhibits or removes wax and/or hydrate formation in production fluid therein without the previous necessity of using a chemical injection system to inject plug-inhibiting chemicals into the interior of the tubing string.Type: GrantFiled: March 17, 2000Date of Patent: July 16, 2002Assignee: Halliburton Energy Services, Inc.Inventors: Carey J.
