Abstract: A method for removing a flapper seat assembly that is replaceable from a safety valve positioned downhole in a wellbore is described herein. For example, the safety valve is positioned downhole in a wellbore and can include a housing. Additionally, the safety valve can include a flow tube coupled to a downhole tool. The flow tube can be removed from the safety valve in response to a first force applied by the downhole tool. A first tool profile can be coupled to a first assembly profile for coupling the downhole tool to the flapper seat assembly after removing the flow tube. A second assembly profile can be detached from a housing profile to remove the flapper seat assembly from the wellbore in response to a second force applied by the downhole tool. After removing the flapper seat assembly, a second flapper seat assembly can be attached to the safety valve.

Abstract: Systems and methods of the present disclosure relate to control of a downhole tool via at least one radio isotope. The radio isotope(s) is pumped from the surface to contact an isotopic analyzer of the tool. The isotopic analyzer reads the isotope and directs the tool to perform a specific action(s) in the wellbore based on the type of isotope read by the analyzer.

Abstract: Multiple layers of a seal can be formed to pressure-seal an open-hole wellbore in a subterranean formation. The seal can include at least one element and a sealing mixture between the element and a container housing for pressure sealing the open-hole wellbore between the element and the container housing and for providing multiple layers of seal in the open-hole wellbore. The seal can be retained by the sealing mixture subsequent to the sealing mixture being released.

Abstract: Systems and methods of the present disclosure relate to actuator assemblies for downhole tools. An actuator assembly comprises a motor, a spring and a hammer. The spring is adjacent to the hammer, and the hammer operable to compress the spring. The spring is operable to expand. The assembly also includes an anvil adjacent to the hammer. The anvil is operable to move a portion of the downhole tool.

Abstract: Provided is a sealing ring and a sealing system. The sealing ring, in one aspect, includes a sealing ring member having an inside diameter face, an outside diameter face, a primary seal side face, and a gland side face. The sealing ring according to this aspect further includes a secondary seal coupled to at least one of the inside diameter face, the outside diameter face, the primary seal side face or the gland side face.

Abstract: A method for dissipating force within a tubing string including providing a severing device to a desired location within a tubing string; a cut zone along the length of the tubing, and a housing disposed along the length of tubing and sized to enclose the cut zone therein, wherein the housing includes a first end and a second end each forming a housing shoulder, severing the tubing at the cut zone using the severing device creating a first tubing section and a second tubing section; wherein the first tubing section and the second tubing section slide apart within the housing.

Abstract: Certain aspects and features of the disclosure relate to a hydraulic connector for use in a wellbore, for example, with or as part of a disconnect tool. The hydraulic connector can isolate hydraulic fluids in upper and lower hydraulic lines using hydraulic pistons. The pistons in the upper and lower parts of the hydraulic connector interconnect mechanically when the connector is engaged and communicate pressure without transferring hydraulic fluid across the interface. The hydraulic fluid can therefore remain confined within the upper and lower hydraulic lines even when the disconnect tool is disengaged, reducing or eliminating incidents of hydraulic fluid leaking or spilling into the wellbore.

Abstract: A tubular control conduit is disposed in a wellbore having a retractable segment and an abandonable segment, each having an inner bore. Upon retraction of the retractable segment an obstruction member is actuated to form a seal thereby preventing the flow of fluid past the obstruction member in the inner bore of the abandoned segment. Cement is then poured into the wellbore thereby covering the abandoned segment of the tubular control conduit.

Abstract: A method includes deploying a tool in a well. The method also includes providing a conductive path with a segmentation module in the well. The method also includes conveying power and telemetry signals from a surface or uphole interface to the tool via the conductive path, where conveying the power and telemetry signals includes the segmentation module decoupling and later coupling power and telemetry signals conveyed along the conductive path.
