Abstract: Apparatus for a drop ball activated device, where a ball seat is concentrically and axially slidably disposed within an outer sleeve having a first internal cylindrical surface, wherein the ball seat comprises at least one radially extending lug, which in a first position extends radially inwards from the internal cylindrical surface, thereby defining a first ball seat diameter less than the diameter of the drop ball. The sleeve comprises at least one groove in its internal surface, and the lug may be received in the groove, thereby defining a second ball seat diameter at least as large as the diameter of the drop ball.

Abstract: A diverting tool includes a ramp repositionable from a first position to a second position, a biasing member in operable communication with the ramp biasing the ramp toward the second position, and a tubular in operable communication with the ramp and the biasing member. The tubular prevents repositioning of the ramp when longitudinally overlapping with the ramp and allows repositioning of the ramp when not longitudinally overlapping with the ramp.

Abstract: A stop collar or like device is formed in one piece to have a portion for a tool to be attached. Movement of the tool allows the collar to be drawn tightly into engagement onto a pipe or other tubular member. A bow centraliser has alternate bows longitudinally offset to reduce initial insertion force. The centraliser may be formed to have end bands of the type used in the stop collar.

Abstract: A method and apparatus for rapidly installing or withdrawing a sealing liner into or out of a subsurface well bore or borehole. An eversion aid, such as an open-ended cylinder, is engaged with the liner, the eversion aid serving to push the liner down the borehole during installation, and to assist in proper liner extraction during its withdrawal from the borehole. Water is transferred between the liner interior and the borehole outside the liner to regulate the disposition of borehole water, and to aid in proper sealing functions of the liner and to promote proper liner extraction during withdrawal.

The method can include supporting a second tubular member with a support surface of the clamping apparatus, feeding a downhole line through a pass through channel formed between the clamping apparatus and a tubular member, and communicating the downhole line with a tool. The clamping apparatus can include two halves, each with support arms, connecting walls, and grips.

Abstract: A method of producing a well fluid includes securing a motor to a string of outer tubing and lowering the outer tubing and motor into the well. A rotary pump is secured to a string of inner tubing and lowered into the outer tubing. The pump stabs into cooperative engagement with the motor. Supplying power to the motor rotates the pump, causing well fluid to flow into the outer tubing to an intake of the pump, which pumps the well fluid through the inner tubing to an upper end of the well. Removing the well fluid allows gas to flow up an annulus surrounding the outer tubing to the upper end of the well.

Abstract: A downhole drilling tool includes a housing defining an axial passageway and a shaft mounted for rotation within the axial passageway such that the housing and shaft form an annular gap. An electrical connector provides a signal to the shaft. The electrical connector includes a first lead assembly coupled to the housing and the shaft, and a second lead assembly coupled to the housing and the shaft. Each lead assembly has an outer ring electrode fixed to the housing and an inner ring electrode fixed to the shaft for rotation therewith such that connector gaps are formed between the outer ring electrodes and the inner ring electrodes. Drilling fluid is pumped through the annular gap to flow through the connector gaps to complete electrical connections between the outer ring electrodes and inner ring electrodes.

Abstract: A system for operating downhole equipment in a well includes a drive shaft extending from a surface of the well to a downhole location. A motor is positioned at the surface and is operably connected to the drive shaft to selectively rotate the drive shaft. A lift system is positioned at the surface and is operably connected to the drive shaft to axially lift and lower the drive shaft.

Abstract: An apparatus for use in deployment of downhole tools is disclosed. Preferably, the apparatus includes at least an in-ground well casing, a housing providing a hermetically sealed electronics compartment, a tool attachment portion, and a first flow through core. The housing is preferably configured for sliding communication with the well casing. The hermetically sealed electronics compartment secures a processor and a location sensing system, which communicates with the processor while interacting exclusively with features of the well casing to determine the location of the housing within the well casing. A preferred embodiment further includes a well plug affixed to the tool attachment portion, the well plug includes a second flow through core capped with a core plug with a core plug release mechanism, which upon activation provides separation between the second flow through core and the core plug, allowing material to flow through said first and second flow through cores.

Abstract: Cutting elements have substrates including end surfaces. TSP material layers extend over only a portion of the end surfaces or extend into the substrates below the end surfaces. Bits incorporate such cutting elements.

Abstract: Systems and methods for the production of hydrocarbons from a wellbore. One or more combination tools can be disposed along a casing string inserted into a wellbore. Each combination tool can contain a body having a bore formed therethrough; a sliding sleeve at least partially disposed in the body; one or more openings disposed about the body at a first end thereof; and a valve assembly and a valve seat assembly at least partially disposed within the bore at a second end thereof. While initially permitting free bi-directional flow of fluids within the casing string, the sliding sleeve within each combination tool can be manipulated to close the valve within the tool, thus permitting pressure testing of the casing string. The sliding sleeve can be further manipulated to open the one or more openings thereby permitting hydraulic fracturing and production of a hydrocarbon zone surrounding the combination tool.

Abstract: An open hole packer uses mandrel expansion and a surrounding sealing element that can optionally have a swelling feature and further a seal enhancing feature of a ring with an internal taper to match an undercut on the mandrel exterior. As a swage progresses to the taper at the transition between the ring and the extending flat fingers, the fingers get plastically deformed in an outward radial direction to push out the sealing element. Shrinkage of the mandrel axially due to radial expansion brings a ring on the mandrel outer surface under the fingers to act as a support for the fingers against the seal which is pushed against the open hole. Mirror image orientations are envisioned to aid in retaining pressure differentials in opposed directions. Another external mandrel ring extends into the seal to keep its position during differential pressure loading.

A patch assembly is provided which includes a tubular patch sub which is radially surrounded by an inflatable boot. A setting tool is used to set the patch assembly within the casing. The setting tool includes a heated barrel that contains eutectic material in liquid form. When actuated from the surface, eutectic material is flowed from the setting tool to the boot of the patch assembly. The eutectic material inflates the boot to secure the patch sub at a desired location within the wellbore.
