A release assist assembly and method for downhole tools, and a double grip packer having the release assist assembly installed therein wherein the release assist assembly operates under high downhole pressure conditions to relax and decompress the packing element of the packer to allow the slips of the packer to be released for mechanically retrieving the packer from the well.

Release assist assembly, and method, for double grip packer with opposed slips

A catching tool assembly, and method of use, for catching an electric submersible pump string or other equipment string in a well bore in the event of a tubing failure. The catching tool is self-orienting so that the tool can be set and retrieved by simply moving the mandrel of the tool up and down, without any need to rotate the equipment string or the mandrel.

Downhole catching apparatus and method

The present invention is to a packer plug that can be tripped into a particular location in a well bore and set using slips or expansion rings and packer elements. The plug presents little flow resistance because of its wide inner diameter throat through the mandrel. A ball seat at an upper end allows for the sealing of the interior passage. The ball can be flowed upward or dissolved to remove the seal and allow flow through the plug.

IPacker bridge plug with slips

An isolation tool that is installed in a well by a setting tool to isolate at least a portion of the well. Preferably, the isolation tool is a plug and the plug and setting tool are configured to prevent premature setting of the plug. Preferably, the plug includes one or more portions that directly connect the plug to a setting tool wherein the one or more portions of the plug shear during setting of the plug in an operating position. In a most preferred form, the plug includes first and second longitudinally spaced portions that directly connect the plug to a setting tool wherein the first and second portions shear during setting of the plug in an operating position. In a most preferred form, the plug and setting tool are configured so that no portion of the setting tool shears during the installation of the plug, separation of the plug from the setting tool and removal of the setting tool.

Apparatus for isolating one or more zones in a well

A valve for use in fracing through cement casing in a well allows for flow of cement down the well during the cementing process and in the open position allows for fracing fluid to be directed through the cement casing for fracturing the formation adjacent the valve. The valve is constructed so as to reduce the likelihood of the valve to jam as a result of cement or other foreign material.

Valve for hydraulic fracturing through cement outside casing

A valve includes: a housing; a mandrel disposed in the housing; a rupture disk disposed in a passageway of the mandrel; a sliding sleeve disposed between the housing and the mandrel; and a ball seat disposed in the mandrel. A method for actuating a valve includes: flowing a fluid through the valve; dropping a ball; seating the ball in the ball seat and blocking fluid flow through the mandrel; flowing fluid through the passageway to the sliding sleeve; moving the sliding sleeve axially within the valve; and exiting fluid through the openings of the housing and mandrel. A valve includes: a housing having an opening; a mandrel disposed in the housing; a sliding sleeve disposed between the housing and the mandrel; and a ball seat disposed in the mandrel blocking fluid communication between the mandrel and the passageway.

The present invention is to an internal sleeve slidably received within a tubular housing. The sleeve and outer housing have windows that selectively align. Movement of the sleeve within the housing is controlled by a ball passing through the interior of the sleeve to activate a ratchet that allows the sleeve to move a set amount under the influence of a spring. A split seat at a lower end of the housing traps after a set number of balls have passed through the housing. A number of similar tools can be used to provide openings at various points that include coordinated ratchet steps so that only one tool at a time opens for fracturing or other purposes. A reverse flow causes a ball to impinge upon the next higher ball seat and thereby opening the seat to provide a full bore flow passage through the tool.

Step ratchet fracture window system

The present invention provides a tool capable of being set and released. A novel arrangement of a push sleeve in the spring body eliminates several shear pins while an internal J slot formed directly on the mandrel significantly reduces the size of the lower drag body and thus the length of the tool. An internal pathway between the inner mandrel and the mandrel body selectively provide increase flow through the packer tool to facilitate running in of the tool.

Patriot retrievable production packer

In order to prevent premature separation of the slip and slip spring and to simplify production of the slip casing, a self-centering spring engageable with a packer tool slip is modified according to the present invention. A groove located at a lower center of the slip below the pocket of the slip cooperates with the spring to retain the spring against the slip and is centered within the pocket without requiring partitions or further welding of lugs to retain the springs.
