Stinger for actuating surface-controlled subsurface safety valve
A system used downhole in tubing is operable with pressure communicated via at least one control line. The system includes a tool and a stinger. The tool disposed with the tubing has a tool bore for passage of tubing flow. The tool has an operator movable between operable states, and the operator has a tool key disposed in the bore. The stinger removably disposed in the tubing is configured to insert into the tool bore. The stinger has an actuator in communication with the at least one control line. Actuated by the control line, a stinger key disposed on the stinger is movable with the actuator between positions. In this way, the stinger key is configured to engage the tool key and is configured to move the tool's operator at least from the one state to another.
Methods and apparatuses for gaining reentry below abandoned packers
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.

Method for incorporating scrapers in multi zone packer assembly
Provided is a method for deploying a multi-zone completion assembly, as well as a downhole tool and a well system. In one aspect, the method for deploying the multi-zone completion assembly includes coupling a casing scraper assembly to an inner service tool string hanging from a beginning section of a packer assembly suspended from a rig floor, the inner service tool string located within and extending below the beginning section of the packer assembly, and the casing scraper assembly located entirely below the beginning section of the packer assembly string. In one or more other aspects, the method includes completing the packer assembly string from the rig floor as the inner service tool string and casing scraper assembly are hanging therefrom.
Universal wireless actuator for surface-controlled subsurface safety valve
Apparatus and methods pertaining to an adapter mechanically connecting a wireless actuator to an SCSSV subassembly that includes an SCSSV. The adapter mechanically connects to the SCSSV subassembly so that the adapter is situated uphole of the SCSSV subassembly when set in a tubular of a wellbore. An actuating piston is carried by the adapter. The actuating piston transfers an opening force to the SCSSV in response to receipt by the adapter of pressurized fluid from the wireless actuator, thereby opening a flapper of the SCSSV.

MULTILATERAL JUNCTION WITH TWISTED MAINBORE AND LATERAL BORE LEGS
Provided is a multilateral junction (MLT), a well system, and a method for forming a well system. The MLT, in one aspect, includes a y-block having a housing with a single first bore and second and third bores extending therein, the second and third bores defining second and third centerlines. The MLT, in this aspect, further includes a mainbore leg having a first mainbore leg end coupled to the second bore and a second opposing mainbore leg end, and a lateral bore leg having a first lateral bore leg end coupled to the third bore and a second opposing lateral bore leg end. In this aspect, the mainbore leg and the lateral bore leg are twisted with respect to the second and third bore such that a first plane taken through centerlines of the second opposing mainbore leg end and the second opposing lateral bore leg end is angled.
