IPC: E21B33/12
Filed: 2017-02-01
Abstract: The method involves, in a single economical trip, running a tool comprising a casing cutter into a wellbore 10 to be plugged and abandoned. A bridge plug 24 may be placed on the same run or may be preplaced and then a calculated quantity of fluidized plugging material 22 e.g. cement, passed through the cutter to form a plug. The tool is at least partially withdrawn and the casing 36 pulled and cut by e.g. deployable cutting members 28, at a suitable location, for recovery. The cutter may be a pipe, milling, laser or chemical cutter. The casing cutter may have a central through bore 26 including a wall to isolate a cutting assembly, housed within the wall, from the cement passing through the cutter. Tungsten carbide cutting members may be deployed by axially moving an internal sleeve acting as a choke by dropping a sponge ball also acting as a tubing cleaner and cement and circulating fluid separator.

Title: Sensing tension in a rope
Inventor: PETER FARTHING
IPC: G01L5/101
Filed: 2020-06-15
Abstract: A sensor assembly for sensing tension in a rope is disclosed. The sensor assembly comprises: a housing, a force sensor for sensing mechanical force applied to the housing located outside the housing, and a controller for controlling the force sensor located inside the housing. The housing protects the controller from damage resulting from compression and/or environmental conditions, such as water ingress.
