Abstract: An impact generator includes a housing having an uphole end and a downhole end and defining a chamber therein between the uphole and downhole ends. A mandrel is movably arranged at least partially within the chamber between an engaged configuration and a disengaged configuration, and a top sub is coupled to the housing at the uphole end and has an upper core extension arranged at least partially therein. The upper core extension is configured to move between a fixed position, where the mandrel is maintained in the engaged configuration, and an unfixed position, where the mandrel is able to move to the disengaged configuration. An impact tool is coupled to a distal end of the mandrel to deliver an impact force to a downhole obstruction when the mandrel is moved to the disengaged configuration.

Abstract: A tool string includes at least one downhole tool having an electronics package associated therewith, and an air shock tool having a housing operatively coupled to the downhole tool. The air shock tool has a piston movably arranged within a piston chamber defined in the housing, and the electronics package is operatively engaged with the piston such that axial movement of the electronics package correspondingly moves the piston. If a shock impact load propagates through the tool string in an uphole direction, the piston operates to reduce the shock impact assumed by the electronics package.

Abstract: Disclosed are systems and methods of minimizing shock impacts assumed by electronics arranged within downhole tools. One disclosed tool string includes at least one downhole tool having an electronics package associated therewith, and an air shock tool having a housing operatively coupled to the at least one downhole tool and having a piston movably arranged within a piston chamber defined in the housing, wherein the electronics package is operatively engaged with the piston such that axial movement of the electronics package correspondingly moves the piston, and wherein a shock impact propagates through the tool string in an uphole direction and the piston is configured to reduce an effect of the shock impact on the electronics package.

Abstract: Disclosed is an impact generation tool used to deliver a large downhole impact force. The impact generator may include a housing having an uphole end and a downhole end and defining a chamber therein between the uphole and downhole ends, a mandrel movably arranged at least partially within the chamber between an engaged configuration and a disengaged configuration, a top sub coupled to the housing at the uphole end and having an upper core extension arranged at least partially therein, the upper core extension being configured to move between a fixed position, whereby the mandrel is maintained in the engaged configuration, and an unfixed position, whereby the mandrel is able to move to the disengaged configuration, and an impact tool coupled to a distal end of the mandrel and being configured to deliver an impact force to a downhole obstruction when the mandrel is moved to the disengaged configuration.

Abstract: A method and apparatus for setting a subsurface device in a wellbore is disclosed. A downhole power unit comprises a power rod and a drive shaft. The power rod comprises a hollow interior. The drive shaft is located within the hollow interior, and the power rod is operable to selectively engage a subsurface device to be positioned downhole.

Abstract: An adjustable fence that provides a surface acting as a support and stop and includes an angled face with a measurement device thereon and further includes a plurality of grooves in which attachments such as clamps, miter gauges, stops, guides, jigs or fixtures are readily affixed.

Abstract: A modified in-situ retort for the retorting of oil shale is constructed by mining an open space having a volume of twenty-five to thirty-five percent of the volume of the retort in the bottom of the retort and thereafter blasting the oil shale that is to remain in the retort as rubble in a manner to cause random free fall of the shale particles onto the rubblized bed. Blasting occurs sequentially from the bottom of the unfragmented shale immediately above the open space to the top of the retort. At each blast, there is an open space below the shale to be broken in the blast having a volume at least one-third the volume of that shale, and the timing of the blasts is such that movement of the broken shale is not interfered with by shale broken in the preceding blast. There is no withdrawal of oil shale that would cause downward movement of the rubble that is to be retorted in-situ. The resultant in-situ retort is characterized by a high and uniform permeability.

Abstract: An in-situ retort is formed in an oil shale deposit by a sublevel caving method in which the starting slot for the sublevel caving is at opposite ends of the retort on adjacent sublevels. Any zones of high permeability that are formed adjacent to the starting slots are limited in vertical extent to the vertical spacing of the sublevels and are spaced from the zones of high permeability in adjacent sublevels by the length of the retort. A source of channeling through the retort that is caused by the usual sublevel caving mining method is thereby eliminated.
