20100206572 | STAGE CEMENTING TOOL - A cementing tool for use in a well has a housing and a closing sleeve received thereabout. An operating sleeve is received in the housing and is interconnected with the closing sleeve so that movement in the operating sleeve will cause the closing sleeve to move. The closing sleeve is detachably connected to the housing and is movable from the first or open position to a second or closed position in which it covers cementing ports defined in the housing. The tool has a plurality of lock rings that are moved with the closing sleeve. A plurality of locking grooves are adapted to receive the lock rings such that the engagement of any of the lock rings with any of the locking grooves will prevent the closing sleeve from moving out of the closed position. | 08-19-2010 |

The impervious body is configured to prevent passage of fluid therethrough. The sealing element is disposed about the impervious body. The energy source is operationally connected to the sealing element. The trigger is configured to transfer energy from the energy source to the sealing element. The trigger is activated, at least in part, by receiving a signal from a pump tool passing through an interior of the impervious body. | 01-17-2013 |

20130180731 | Pressure Activated Down Hole Systems and Methods - Systems and methods for activating a down hole tool in a wellbore. A trigger is moveably positioned in the interior of a base pipe and includes a first end and a second, smaller end. The trigger is moveable between an unactivated position where a port in the base pipe is blocked and an activated position where the port is open. At least one latch member prevents movement of the trigger from the unactivated position to the activated position until a predetermined force is applied to the trigger. Increasing pressure in the interior increases a force differential between the first end and the second end. When the force differential is substantially equal to the predetermined force, the latch releases and allows the trigger to move from the unactivated position to the activated position, thereby opening the port to permit activation of the down hole tool. | 07-18-2013 |
20130233572 | External Casing Packer and Method of Performing Cementing Job - A packer that includes a mandrel, primary and secondary opening seats attached to an interior of the mandrel, a landing seat attached to the interior of the mandrel, a packer element attached to an exterior of the mandrel, and a closing seat attached to the interior of the mandrel. The secondary opening seat may be between the primary opening seat and the landing seat, and the primary opening seat may be between the closing seat and the secondary opening seat. The primary opening seat engages an opening plug and moves from a first position covering an opening to a second position not covering the opening, and the secondary opening seat engages the primary opening seat and moves from a first position covering a port to a second position not covering the port. | 09-12-2013 |
20140048263 | Pressure Activated Down Hole Systems and Methods - Systems and methods for activating a down hole tool in a wellbore. A piston is moveable from a first position to a second position for activating the down hole tool. The piston includes a first side exposed to an activation chamber, and a second side operatively coupled to the down hole tool. A rupture member has a first side exposed to the activation chamber and a second side exposed to the interior of a base pipe. The rupture member is configured to rupture when a pressure differential between the activation chamber and the interior reaches a predetermined threshold value, at which point the rupture member allows fluid communication between the interior and the activation chamber to pressurize the activation chamber and move the piston, thereby activating the down hole tool. | 02-20-2014 |
20140048281 | Pressure Activated Down Hole Systems and Methods - Systems and methods for activating a down hole tool in a wellbore. A piston is moveable from a first position to a second position for activating the down hole tool. The piston includes a first side exposed to a first chamber, and a second side exposed to a second chamber. A rupture member has a first side exposed to the first chamber and a second side exposed to a third chamber. The rupture member is configured to rupture when a pressure differential between the first chamber and the third chamber reaches a predetermined threshold value, at which point the rupture member allows fluid communication between the first chamber and the third chamber. When the rupture member is intact, the piston is in the first position, and when the rupture member ruptures, the piston moves to the second position and activates the down hole tool. | 02-20-2014 |
20140083713 | Secondary System and Method for Activating a Down Hole Device - Disclosed is a secondary system and method for initiating a down hole operation in a wellbore when a primary activation system fails. The primary activation system is configured to provide fluid communication between a first chamber and a second chamber in response to a primary activation operation. The secondary activation system includes a passageway between the first chamber and the second chamber, and a rupture member positioned in the passageway. The rupture member has a threshold pressure differential at which the rupture member ruptures to afford fluid communication between the first chamber and the second chamber to thereby initiate the down hole operation if the primary activation system fails. The primary activation operation may be configured to move a trigger member to initiate the down hole operation, whereas the secondary activation operation may be configured to initiate the down hole operation without moving the trigger member. | 03-27-2014 |
20140116699 | Pressure Relief-Assisted Packer - A wellbore completion method comprising disposing a pressure relief-assisted packer comprising two packer elements within an axial flow bore of a first tubular string disposed within a wellbore so as to define an annular space between the pressure relief-assisted packer and the first tubular string, and setting the pressure relief-assisted packer such that a portion of the annular space between the two packer elements comes into fluid communication with a pressure relief volume during the setting of the pressure relief-assisted packer. | 05-01-2014 |
