A downhole access tool for accessing a lateral branch of a wellbore includes a tool body, a sliding sleeve, and a deflector device including a deflector plate and a deflector actuator operatively coupled to the deflector plate. A central conduit extends axially through the downhole access tool. The sliding sleeve is slidable relative to the tool body in an axial direction between a closed position and an open position. In the closed position, the sliding sleeve restricts access through the opening. In the open position, the sliding sleeve permits access through the opening. The deflector actuator transitions the deflector plate between a deflection position and a passthrough position. In the deflection position, the deflector plate deflects tooling radially outward towards the opening. In the passthrough position, the deflector plate allows access axially through the central conduit.

A downhole system is deployed on wireline and includes a tool and a guide system on it a lower end of the tool for navigating past obstacles within a wellbore. A selectively rotatable tip member projects downward from the guide system. A side of the tip member is curved, so when the tool encounters cm obstacle downhole, the tip member rotates so the curved side faces the obstacle and the downhole system can be urged past the obstacle. The guide system includes a sleeve and pedestal that abut one another on opposing ends that are complementarily profiled. When the sleeve and pedestal axially contact one another, the profiled ends produce relative rotation of the sleeve and pedestal. The pedestal is coupled with the tip member and the sleeve is coupled to the tool, so that the relative rotation of the sleeve and pedestal causes the tip member to rotate relative to the tool.

A transition device for deploying instrumentation below a downhole tool, such as a downhole pump, employed in hydrocarbon recovery operations can include a housing serially connectable between the downhole tool and a guide string insertable into the well ahead of the downhole tool. The transition device can also include a sealable crossover channel extending through the housing and having a proximal and a distal end, the crossover channel providing a crossover path for at least one instrumentation line between an exterior of the transition device at the proximal end and an interior of the guide string at the distal end. The fluid channel can extend through the housing and be radially offset from and capable of establishing fluid communication with the crossover channel, the fluid channel being configured to provide a pressurized fluid into the crossover channel to propel the at least one instrumentation line forward inside the guide string.

A method includes introducing a bullnose assembly into a main bore of a wellbore, the bullnose assembly including a body and a bullnose tip actuatable between a default configuration, where a collet body forming part of the bullnose tip exhibits a first diameter, and an actuated configuration, where the collet body exhibits a second diameter different than the first diameter. The bullnose assembly is then advanced to a deflector arranged within the main bore and defining a first channel that exhibits a predetermined diameter and communicates with a lower portion of the main bore, and a second channel that communicates with a lateral bore. The bullnose assembly is then directed into either the lower portion of the main bore or the lateral bore based on a diameter of the collet body as compared to the predetermined diameter.

A Y-tool is configured for use with a pumping system that includes an electric submersible pump and bypass tubing. The Y-tool includes a slave valve assembly that controls access to the bypass tubing. The Y-tool also includes a master valve assembly driven by pressure from the electric submersible pump and a linkage assembly connected between the master valve assembly and the slave valve assembly.

Systems and methods usable to operate on a plurality of wells through a single main bore are disclosed herein. One or more chamber junctions are provided in fluid communication with one or more conduits within the single main bore. Each chamber junction includes a first orifice communicating with the surface through the main bore, and one or more additional orifices in fluid communication with individual wells of the plurality of wells. Through the chamber junctions, each of the wells can be individually or simultaneously accessed. A bore selection tool having an upper opening and at least one lower opening can be inserted into the chamber junction such that the one or more lower openings align with orifices in the chamber junction, enabling selected individual or multiple wells to be accessed through the bore selection tool while other wells are isolated from the chamber junction.
