n: a wire-rope strand design that consists of a single, central wire surrounded by two outer layers of several wires. The wires in the inner layer are the same diameter as the inner wire. The wires in the outer layer are of two diameters, one smaller wire laying adjacent to one larger wire. A typical Warrington strand ahs 19 wires: 1 central wire, 6 inner wires, and 12 outer wires, 6 of which are smaller in diameter than the other 6.

v: to release pipe that is stuck in the hole by running washover pipe. The washover pipe must have an outside diameter small enough to fit into the borehole but an inside diameter large enough to fit over the outside diameter of the stuck pipe. A rotary shoe, which cuts away the formation, mud, or whatever is sticking the pipe, is made up on the bottom joint of the washover pipe, and the assembly is lowered into the hole. Rotation of the assembly frees the stuck pipe. Several washovers may have to be made if the stuck portion is very long.

v: A type of milling operation in which the outer surfaces of a plug or similar fish are milled with a circular hollow mill. By including wash pipe in the tool string, the mill face can reach over the body of the fish until it can be pushed to bottom, or unt

a recovery process in which a larger pipe is used with circulation to surround and capture a pipe stuck in sand or cuttings. Circulation is critical to washing the sand from around the fish. Can be used with normal or reverse circulation.
