摘要： A downhole tool comprising a housing having at least one flow port disposed providing a communication path between the interior and exterior of the sleeve. A sleeve assembly has an expandable seat and an inner sleeve, and is moveable within the housing between a first position and a second position, wherein in the first position the sleeve assembly is radially positioned between the flow ports and the flowpath to substantially prevent fluid communication. Shearable port inserts are positioned within the flow ports, with each port insert having a shearable portion extending into the interior of the housing and engaging the sleeve assembly when the inner sleeve is in said first position.

摘要： A shifting tool and method of shifting a downhole device that requires only a minimal profile or no profile to engage and move the movable portion of the tool. The invention comprises a ported housing assembly and at least one friction pad alignable with said at least one port and radially movable through the port between a first pad position and a second pad position. In the second pad position, the friction pad extends outside said outer diameter of said housing assembly to engage the targeted downhole device. A mandrel positioned through the ported housing has a first section with a first outer diameter and a second section with a second outer diameter, said second outer diameter being greater than said first outer diameter. The mandrel is movable between a first mandrel position and a second mandrel position. In the second mandrel position, the second outer diameter supports the friction pads in the second pad position.

摘要： A downhole tool comprising a first section having an internal sidewall defining at least a portion of a flowpath, and a ported outer sidewall and an explosive having at least a portion within said first section. An annular portion has at least one chamber having an end positioned adjacent to the explosive and an inlet providing a communication path to said flowpath. A detonator assembly is located within each chamber proximal to the explosive such that detonation of the assembly causes detonation of the explosive. A firing pin is propelled toward the detonation assembly by providing communication between the chamber and the flow path, causing a pressure differential between the pressure isolated ends of the firing pin.

摘要： A system and method for fracturing a stage of a multiple stage hydrocarbon production well. One embodiment of the system comprises at least one ported sleeve assembly and a flapper assembly positioned downwell of the ported sleeve assembly. Each ported sleeve assembly comprises a ported housing having a plurality of ports disposed radially therethrough; a first sleeve at least partially within the ported housing and moveable between a first position and a second position, wherein in the first position the first sleeve is radially positioned between the plurality of ports and the flowpath. The first sleeve has an exterior surface, a first slot formed in the first exterior surface, and a first engagement surface having a first inner diameter. A first guiding member is fixed relative to the ported housing and positionable within the first slot. A first compression spring positioned between the a upper end of the first sleeve and the ported housing, the first compression spring being under compression when the first sleeve is in the first position. The flapper assembly comprises a flapper seal; a flapper plate rotatable between an opened position and a closed position, wherein in the opened position fluid flow in the downwell direction through the flapper seal is at least substantially unimpeded, and wherein in the closed position the flapper plate is engaged against the flapper seal to at least substantially prevent fluid flow through the flapper seal in the downwell direction; a second sleeve moveable between a first position and a second position, wherein in the first position at least a portion of the second sleeve is radially positioned between the flapper plate and the flowpath, the second sleeve having a second exterior surface, a second slot formed in the second exterior surface, and a second engagement surface having a second inner diameter; a second guiding member fixed relative to the flapper seal and positionable within the second walking jay slot; and a second compression spring positioned between an upper end of the second sleeve and the flapper seal, the second compression spring being under compression when the second sleeve is in the second position.
