Systems and methods are provided to assist with landing a component, e.g. a blowout preventer or production tree, having a female connector onto a male component which may be a mandrel extending from a top portion of the production tree or a wellhead, respectively. Thrusters are located between the component and the mandrel or wellhead, respectively, extending radially and connected to the bottom portion of the component. Activation of a thruster will cause the component to move in a direction away from the activated thruster. Real-time data is collected related to the position of the component relative to the mandrel or wellhead, respectively, and is used to determine which the thrusters to activate. The component is thus caused to move in a desired direction, until the female connector can be lowered onto the male component thereby engaging the blowout preventer or production tree with the mandrel or the wellhead, respectively.

A wellbore whipstock tool assembly includes a body that includes an uphole axial surface that is slanted from one portion of an edge of the uphole axial surface to another portion of the edge of the uphole axial surface, a downhole axial surface opposite the uphole axial surface, and a radial surface between the uphole axial surface and the downhole axial surface; one or more keys formed on the radial surface and configured to secure into one or more keyholes formed in a casing of a wellbore; and a bore that extends between an opening in the uphole axial surface and an opening in the downhole axial surface, the bore sized to receive a bottom hole assembly of an intervention tool.

A downhole communications system comprises a power generator disposed proximate a predetermined portion of a side pocket mandrel in such a way as to not impede fluid flow within a wellbore into which the side pocket mandrel is disposed and a wireless communications transmitter operatively in communication with the power generator. Placed at least partially within a side pocket mandrel, the system allows fluid flowing proximate the side pocket mandrel to engage the power generator to create electric energy which may be used to power the wireless communications transmitter and allow data interchange between the wireless communications transmitter and a predetermined well device.

Systems and methods include a plug activated mechanical isolation device that controls fluid flow inside a tubular in a wellbore. The device includes a sleeve for coupling to the tubular, and the sleeve includes an internal bore and port for fluid flow therethrough. A channel element is positioned in the internal bore and includes an internal channel and an orifice for fluid flow between the internal channel and internal bore. The channel element is attached to the sleeve via a breakable attachment portion, and the orifice is aligned with at least one port of the sleeve. The channel element is slidable within the sleeve, upon breakage of the breakable attachment portion with a force, to move the orifice out of alignment with the port of the sleeve so that a portion of the channel element covers the port of the sleeve to block fluid flow through the port.
