    Abstract: Embodiments may generally take the form of a safety joint and methods related thereto. One embodiment may take the form of a safety joint deployable in a well. The safety joint includes a first sub and a second sub coupled to the first sub. The coupling of the two subs may include a first set of threads having a first orientation and a second set of threads having a second orientation different from the first set of threads. The first sub is decoupleable from the second sub upon disengagement of the first set of threads by rotation in a first direction followed by disengagement of the second set of threads by rotation in a direction opposite from the first direction.

    Abstract: A methodology and system facilitate performance of an operation in tubing, such as wellbore tubing. A seat is placed in the tubing so that an object may be delivered along an interior of the tubing for engagement with the seat. The object is designed with a non-degradable component, e.g. wiper, mounted on a degradable core. In many applications, fluid may be used to move the object along the interior of the tubing and into engagement with the seat. As the object moves along the interior, the wiper is used to wipe, e.g. scrape, material from an inside surface of the tubing. After the object engages the seat, pressure may be applied along the interior of the tubing to actuate a desired tool. Upon completion of the procedure, the core may be degraded, e.g. dissolved, and thus removed from the tubing.

    Abstract: Various implementations described herein are directed to a vibration tool, e.g., for use in drilling. In one implementation, the vibration tool may include a housing having a bore extending therethrough. The vibration tool may also include a piston subassembly positioned inside the bore, where the piston subassembly is configured to oscillate when fluid flow inside the piston subassembly exceeds a predetermined flow rate. The vibration tool may further include a valve mechanism positioned around the piston subassembly, where the valve mechanism is configured to restrict fluid to flow inside the piston subassembly when the valve mechanism is in a closed state and configured to allow the fluid to flow from the piston subassembly to the bore when the valve mechanism is in an open state.

    Abstract: Methods for determining a distance from a drilling well to a magnetized target well include acquiring magnetic field measurements from the drilling well. The acquired magnetic field measurements are made at a plurality of spaced apart locations in the drilling well. The acquired magnetic field measurements are processed to obtain a ratio including at least one of the following: (i) a ratio of a magnetic field intensity to a first spatial derivative of a magnetic field, (ii) a ratio of a magnetic field intensity to a second spatial derivative of a magnetic field, and (iii) a ratio of a first spatial derivative of a magnetic field to a second spatial derivative of the magnetic field. The ratio (or ratios) is then processed to obtain the distance from the drilling well to the magnetized target well.
