Abstract: An evaporative cooler for cooling drilling fluid includes a flow pipe having an inner surface in contact with drilling fluid and an outer surface in contact with an evaporative medium. The flow pipe has a serpentine configuration within a transportation frame. A system for cooling a drilling fluid includes a mud circulation system connecting the drilling fluid between a well and a surface where an evaporative cooler is coupled to the mud circulation system and has a serpentine flow pipe in a transportation frame. A method includes pumping heated drilling fluid from a wellbore to an evaporative cooling system, with an evaporative cooler to cool the heated drilling fluid, and sending the cooled drilling fluid back to the wellbore. Another method includes using an intermediate cooler, wherein the intermediate cooler comprises a heat exchanger and an intermediate fluid.

Abstract: A mechanical autonomous pipe cutting system for cutting a pipe in a wellbore includes a locking unit that prevents the system from moving within the pipe when engaged to an inner surface of the pipe, a punching unit that moves a plurality of punching elements radially relative to an axis of the system, and a cutting unit that is designed to sever the pipe. The locking unit, the punching unit, and the cutting unit are attached to a body of the mechanical autonomous pipe cutting system. The body includes a motor that rotates the cutting unit. The mechanical autonomous pipe cutting system further includes a sensor module that detects interactions between the pipe and walls of the wellbore and a control unit in electronic communication with the sensor module, the locking unit, and the punching unit. The control unit actuates the locking unit and operates the punching unit subsequent to identifying a location where interaction between the pipe and the walls of the wellbore limits a downhole movement of the pipe based on an output of the sensor module.

Abstract: A self-retaining shear pin tool and methods for connecting downhole tubulars in a wellbore are disclosed. The self-retaining shear pin tool includes a cap having an inner side and an outer side opposite the inner side, the cap defining a first recess formed in the inner side of the cap, the first recess of the cap having a cylindrical portion and a frustoconical portion extending from the cylindrical portion towards the outer side of the cap, and a shear pin disposed partially in the first recess of the cap and extending out of the first recess of the cap. The shear pin includes a body, a first recess extending inward from a first end of the body, a second recess extending inward from a second end of the body, a first swage, and a second swage die.

Abstract: A system including a plug with a first end connected to a lower drill string and a second end connected to an upper drill string. The plug further includes a sealing element configured to seal against a reservoir pressure that is downhole from the plug, and an anchoring element configured to releasably couple the plug to a wellbore to disallow an axial movement of the plug in the wellbore. The plug is configured to couple to a retrieving tool. The retrieving tool includes a first engagement element configured to release the anchoring element, thereby allowing axial movement of the plug and retrieval of the upper drill string in order to shut in the wellbore.

Abstract: A downhole tool includes a bore isolation valve, a sensor configured to receive to a downlink signal, an annular pressure sensor, a valve actuation mechanism coupled to the bore isolation valve and responsive to the downlink signal, a pressure relief mechanism configured to provide a negative pressure pulse signal indicative of the annular pressure by venting fluid from a bore of the tool body, and a battery. A method includes drilling a well with a drill bit coupled to an on demand annular pressure tool initially in a deactivated mode, and activating the tool by a downlink signal when fluid flow out of the annulus drops below the fluid flow into the well to close a bore of the tool, pressurizing the drill string, holding pressure in the drill string, measuring annular pressure with the tool, and sending a negative pressure pulse signal indicative of the annular pressure.

Abstract: A method of deploying a flexible cable in a wellbore includes carrying, by a tubular assembly, a cable spool cartridge into the wellbore. The cable spool cartridge is attached to an exterior of the tubular assembly and contains the flexible cable. A first end of the flexible cable is attached to a buoyancy device, and the buoyancy device is releasably attached to the cable spool cartridge. A fluid is flowed by the tubular assembly in a downhole direction through an interior of the tubular assembly and in an uphole direction within an annulus at least partially defined by the exterior of the tubular assembly. The fluid has a greater density than the buoyancy device. The buoyancy device is released by the cable spool cartridge, and the buoyancy device is configured to travel after release in the uphole direction with the fluid and thereby pull the flexible cable from the cable spool cartridge and into the annulus.
