Patent number: 6920933Abstract: A platform is used to deliver a tool down a hole by controlling the flow of fluid through and around the platform. The platform has a top surface for receiving the tool. The platform also has a bottom surface to provide guidance through and resistance to the flow of fluid. The lower surface of the platform can be engineered to steer the platform against an inner wall of the casing. This slows the descent by adding mechanical friction to its descent. The lower surface can also be engineered to add a predetermined amount of resistance to the flow of the well fluid across it. A stop on the casing already in place in the well stops the descent of the tool at a desired depth. Once the tool is no longer needed, a fishing tool can be lowered from the same crane to retrieve the tool and platform. Use of a crane substantially decreases the cost of the operation compared to the need for a rig.Type: GrantFiled: February 27, 2003Date of Patent: July 26, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Roger C. Watson, Flint R. George

Publication number: 20040118562Abstract: A multi-cycle pressure operated firing head for use in a subterranean well. In a described embodiment, a pressure actuated firing head for detonating a perforating gun in a subterranean well includes a firing mechanism and a member which displaces incrementally in response to alternating pressure increases and decreases applied to the firing head. The firing mechanism fires when the member displaces a predetermined distance. In another embodiment, a firing head includes a firing mechanism and a displacement mechanism which displaces a member of the firing head in response to a decrease in a pressure level proximate the firing head in the well. The firing mechanism fires when the member is displaced by the displacement mechanism.Type: ApplicationFiled: December 20, 2002Publication date: June 24, 2004Inventor: Flint R. George

Patent number: 6708761Abstract: An apparatus (60) for absorbing a shock comprises a first tubular member (62) and a second tubular member (80) that are slidable positioned relative to one another. A plurality of layers (94-104) of energy absorbing members (88) extend radially from the second tubular member (80) such that movement of the second tubular member (80) in a first direction relative to the first tubular member (62) sequentially deforms the layers (94-104) of energy absorbing members (88). As the layers (94-104) are sequentially deformed, a subsequent layer (96) of energy absorbing members (88) begins to deform before the previous layer (94) of energy absorbing members (88) is completely deformed. The deformation of the energy absorbing members (88) absorbs the shock.Type: GrantFiled: November 13, 2001Date of Patent: March 23, 2004Assignee: Halliburton Energy Services, Inc.Inventors: Flint R.

Patent number: 6684954Abstract: A bi-directional explosive transfer subassembly (56) for coupling two explosive tools (52, 54) comprises first (74, 78) and second (76, 80) explosive carrying members that respectively define first (82, 86) and second (84) explosive cavities. A ball end (102) of the first explosive carrying member (74, 78) is slidingly received in a socket (114) of the second explosive carrying member (76, 80) such that the first (74, 78) and second (76, 80) explosive carrying members are rotatable and angularly displaceable relative to one another. A first explosive device (130) is disposed in the first explosive cavity (82, 86) and a second explosive device (132) is disposed in the second explosive cavity (84). The first (130) and second (132) explosive devices are spaced apart such that when one of the explosive devices (130, 132) is initiated, the other of the explosive devices (130, 132) will in turn be initiated.Type: GrantFiled: October 19, 2001Date of Patent: February 3, 2004Assignee: Halliburton Energy Services, Inc.Inventor: Flint R.

Patent number: 6675896Abstract: A detonation transfer subassembly for coupling two detonation activated tools in a work sting such that the work string may be severed between the two detonation activated tools without risk of a detonation. The detonation transfer subassembly comprises first and second explosive carrying members having a detonation transfer member disposed therebetween. The detonation transfer member defines a longitudinal passageway therein. A firing pin is disposed within the longitudinal passageway. The firing pin has a first position proximate the first explosive carrying member and a second position proximate the second explosive carrying member. The firing pin is propellable from the first position to the second position following a detonation within the first explosive carrying member such that the firing pin impacts an explosive disposed within the second explosive carrying member, thereby transferring detonation from the first explosive carrying member to the second explosive carrying member.Type: GrantFiled: March 8, 2001Date of Patent: January 13, 2004Assignee: Halliburton Energy Services, Inc.Inventor: Flint R.
