Abstract: The method can include: sampling measurements of a vehicle in-situ, generating a model based on the measurements, and determining a wash path based on the model. The method can optionally include washing the vehicle according to the wash path.

Abstract: An underreamer for increasing the diameter of a bore. The underreamer includes a substantially cylindrical body having an axial bore therein. A mandrel may extend axially through the axial bore. One or more cutter blocks are movably coupled to the body. A ratio of a height of the cutter block to a diameter of the body is between about 0.35:1 and about 0.50:1.

Abstract: An underreamer for increasing a diameter of a wellbore. The underreamer may include a body having an axial bore extending at least partially therethrough. An electromagnetic activation system may be disposed at least partially within the bore of the body. A valve may be disposed within the bore of the body and coupled to the electromagnetic activation system. The valve may include a mobile element and a static element. The mobile element may be coupled to the electromagnetic activation system and move from a first position where the mobile element obstructs fluid flow through the valve to a second position where the mobile element permits fluid flow through the valve. A cutter block may be movably coupled to the body and move radially-outward as the mobile element moves from the first position to the second position.

Abstract: An underreamer for increasing a diameter of a wellbore. The underreamer includes a body having an axial bore extending at least partially therethrough. A mandrel is disposed within the bore of the body and has a port formed radially therethrough. A sleeve is disposed radially-outward from the mandrel. The sleeve blocks fluid flow through the port in the mandrel when the sleeve is in a first position, and the sleeve is axially-offset from the port in the mandrel when the sleeve is in a second position. A flow tube is coupled to the mandrel. The sleeve moves from the first position to the second position when fluid flows through the flow tube and through a channel disposed in the mandrel. A cutter block is movably coupled to the body and is responsive to fluid flow from the axial bore through the port in the mandrel.
