A multi-stage object drop frac assembly that includes a fracture subassembly is configured for disposal in a well zone. The assembly includes a plurality of filtration media stages configured for disposal in the same well zone. A plurality of valves, one of the plurality of valves being associated with each of the plurality of filtration media stages is a part of the assembly and the plurality of valves are openable simultaneously in response to the same event.

A pressurizable assembly which comprises first and second assemblies. The first assembly has a plurality of cam grooves while the second assembly is size and shaped to intimately receive and mate with the first assembly. The second assembly has a connection member a plurality of radially mounted locking pin mechanisms for interacting with one of the plurality of spaced apart cam grooves. Axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the cam grooves to an intermediate locking position which locks the second assembly with the first assembly, while a subsequent axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the plurality of cam grooves and disengage the second assembly from the first assembly.

A reentry guide tool includes an overshot defining a lower end and comprises a bowl and grapple. The bowl defines an interior space of the overshot, and the grapple is disposed in the bowl and is operable to engage a tubular. A tubular guide nipple has a downhole and an uphole end, the downhole end complementary to the overshot and the uphole end complementary to the reentry guide. The guide nipple is operable to connect and provide a transition between the overshot and reentry guide. The reentry guide is a tubular piece having an uphole end with a bevel. A deployment mechanism is defined on the overshot, reentry guide, or guide nipple, and is operable to connect the reentry guide to a running tool for deployment. A method of providing a transition from a first to a second tubular in a wellbore is also provided.

A mechanical jar including a housing, a piston disposed in the housing and responsive to applied fluid pressure to move in a first direction relative to the housing, a biasing arrangement disposed in the housing and configured to bias the piston in a second direction opposite the first direction, and a restraint configured to prevent movement of the piston in the second direction until a threshold force is applied to the restraint by the piston, whereafter the piston suddenly moves in the second direction.

A tubing hanger orientation assembly includes an annular structure having a first set of engagement surfaces configured to guide an engagement feature from a first end portion of the annular structure to a second end portion of the annular structure in response to longitudinal movement of the annular structure in a first direction. A circumferential extent of the second end portion is less than a circumferential extent of the first end portion. The annular structure includes a second set of engagement surfaces configured to guide the engagement feature from the second end portion of the annular structure to a third end portion of the annular structure in response to longitudinal movement of the annular structure in a second direction. The third end portion extends between a first side of the first end portion and a second side of the first end portion along a circumferential axis of the annular structure.

Provided herein is an intervention tool and a method for fracturing multiple lateral wellbores in a well system. The intervention tool, in one aspect, includes a radial outer housing, the radial outer housing forming an interior bore configured to flow fluid, and an expansion member coupled proximate an outer surface of the radial outer housing. The intervention tool according to this aspect further includes a sliding sleeve positioned along an interior surface of the radial outer housing and engageable with the expansion member, the sleeve including a collection of slots or catches configured to move the expansion member between a radially retracted position when the sliding sleeve is in a first linear position and a radially expanded position when the sliding sleeve is in a second linear position.

A pressurizable assembly which comprises first and second assemblies. The first assembly has a plurality of cam grooves while the second assembly is size and shaped to intimately receive and mate with the first assembly. The second assembly has a connection member a plurality of radially mounted locking pin mechanisms for interacting with one of the plurality of spaced apart cam grooves. Axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the cam grooves to an intermediate locking position which locks the second assembly with the first assembly, while a subsequent axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the plurality of cam grooves and disengage the second assembly from the first assembly.

Provided is a slotted orientation apparatus for use with a keyed running tool. The slotted orientation apparatus, in one aspect includes a tubular having a wall thickness (t), and a slot extending at least partially through the tubular, the slot having an angled portion coupled to an axial portion, wherein the slot radially extends around the tubular X degrees, wherein X is 180 degrees or less.

An uphole end for a compression-set straddle packer has a multicomponent mandrel and a multicomponent sliding sleeve that reciprocates within a limited range on the multicomponent mandrel. A bias element constantly resists relative movement between the multicomponent mandrel and the multicomponent sliding sleeve.
