  • Patent number: 8657006
    Abstract: A method of severing a well string that extends into an oil well from an oil platform with a deck includes supporting upper and lower sections of the well string, the lower section supported at the platform deck with a deck located string support. A shear mechanism cuts the well string at a position that can be above the deck located string support. The upper section is then lifted a selected distance and the deck located string support again supports the string at a position below the cut.

    Abstract: Parts that need to be retained against relative movement are held with at least one collet that is captured in a groove with sleeve that acts as a piston. The piston is exposed to tubing pressure on opposed ends to be in pressure balance despite variations of pressure in the tubing. When it is desired to allow relative part movement to actuate the tool, one of the ports to the piston is isolated from the other and pressure drives the piston in a downhole direction. This releases the collet and drives a sleeve in an opposite direction to actuate a tool. The parts can be optionally rotationally locked.

The design enables the removal of fracture sleeve pistons from between treatment zones without requiring drilling or milling of the sleeve while allowing for full flow of fluids after treatment. A number of plugs or pistons having sequentially smaller central bores allows for balls to sequentially be inserted through the tool to selectively close off the pistons to isolate one zone from another. A release tool may inserted into the tool to engage and unthread the plugs to open up the inner diameter of the tool to allow greater production flow through the tool. The plugs may have mating tabs and holes so that as each plug is unthreaded it falls to the next plug and engages so that each plug may sequentially be unthreaded from the sleeve.

  • Patent number: 8424595
    Abstract: A method and apparatus for releasing a coiled tubing internal line from a bottom hole assembly. The internal line may not have strength sufficient to permit the application of a tension force at the surface to disconnect the internal line from the bottom hole assembly. The bottom hole assembly may include a ball seat adapted to retain a ball permitting the application of a pressure differential above and below the ball seat. An anchor assembly connected to the internal line may be adapted to disconnect from the bottom hole assembly upon the application of predetermined pressure differential. A predetermined pressure differential may be used to shear a portion of the internal line releasing an upper portion of the internal line from the bottom hole assembly.

  • Patent number: 8413726
    Abstract: Apparatus, assembly and process for allowing gas lift operations to be conducted along a relatively long perforated interval below a packer in a generally vertical or a deviated subterranean well. An elongated segregation member may be lowered into locking engagement with a bypass mandrel secured to a tubing string above the packer. This segregation member may be configured and dimensioned to define two fluid flow paths. A first flow path extends from the surface of the earth through the annulus formed between the tubing string above the packer and casing secured in the well, the bypass mandrel, a bore through a portion of the segregation member and the interior of the tubing string below the packer. A second flow path extends from the subterranean region penetrated by the well through the annulus formed between the tubing string below the packer and casing secured in the well, the annulus between the segregation member and the packer, and the interior of the tubing string above the packer.

  • Patent number: 8403064
    Abstract: A completion assembly of a top packer and zone isolation packers separated by screens has a disconnect in a selected zone to be fractured or gravel packed that is armed before such a procedure starts. Initially when the assembly of the outer completion and the inner string are properly located and all the screens valved off, all the packers are pressure set and the packer set release device associated with each packer is armed. Before starting a fracturing or gravel packing operation from a given zone isolation packer, a disconnect for that zone packer is armed so that if the inner string sticks in that packer, the inner string is sheared and removed and another trip is used to grab the top packer and pick up. Such picking up releases all the packers down to the one armed disconnect. The disconnect releases bringing up the remnant of the inner string stuck in the packer just above the actuated disconnect.

  • Patent number: 8393397
    Abstract: An apparatus for separating a tubular string from a subsea well installation. The apparatus includes a heave compensator tensioning the tubular string, a subsea actuator assembly positioned within the tubular string, a subsea controller in communication with the subsea actuator assembly, a subsea safety tree positioned within the subsea well installation and a fluid delivery subsystem. An output signal generated by the subsea controller responsive to receipt of a predetermined input signal releases a piston of the subsea actuator assembly such that the tension in the tubular string shifts the piston relative to a cylinder energizing fluid in the fluid delivery subsystem to actuate the retainer valve, the shut-in valve assembly, the vent sleeve and the latch assembly, thereby safely separating the tubular string from a subsea well installation.

  • Publication number: 20130032358
    Abstract: The present invention is directed to methods for controlling the operations of a well service rig at a well site by evaluating load sensor data obtained from sensors on or associated with the well service rig. A rig load data chart can be reviewed and an average rig load can be determined for each pull of tubing or rods from a well. The average rig load can be used to calculate and set a rig overload level. If the rig load sensor reads a rig load at or above the rig overload level, the clutch for the hoist can be disengaged and the brake applied to prevent the load from either damaging the rig or breaking off the tubing or rods in the well. In addition, the rig load can be evaluated to determine when the limit the block speed when pulling rods or tubing.
