High Quality Washover Shoes for Well Drilling

Construction

Our Washover Shoes are dressed with a special hard-face compound made of crushed sintered tungsten carbide particles and a resilient matrix of nickel-silver alloy. Tungsten carbide particles have a hardness nearly equal to that of diamonds. They retain their hardness at high temperatures and are not affected by the heat generated from the cutting operation. The tough nickel-silver alloy matrix holds the tungsten carbide particles in place and cushions the particles against strong impact.

Styles and Usage

Type A

Cuts on the inside diameter and bottom. Do not cut on the outside diameter. Used to cut metal on fish without cutting the casing.

Type B

Cuts on the outside diameter and bottom. Does not cut on the inside diameter. Used to wash over a fish and cut metal or formation in an open hole.

Type C

Cuts on the inside and outside diameters and bottom. Used to wash over and cut metal, formation, or cement.

Type D Used where clearances are limited. Cuts on the inside diameter and bottom. Do not cut on the outside diameter. Cut metal on the fish without cutting the casing. Type E Used where clearances are limited. Cuts on the outside diameter and bottom. Does not cut on the inside diameter. Used to wash over a fish or cut metal, formation, or cement in an open hole. Type F Used to size and dress the top of a fish inside the casing. Makes a tapered cut on the inside diameter and cuts on the bottom. Do not cut on the outside diameter. Type G Cuts on the inside and outside diameters and on the bottom. Used to wash over a fish or cut metal, formation, or cement in an open hole where inside clearances are limited. Type H Cuts on the inside and outside diameters and on the bottom. Used to wash over a fish or cut metal, formation, or cement in an open hole where outside clearances are limited. Type I Cuts on the bottom only. Does not cut on the inside or outside diameters. The saw-tooth design allows maximum circulation. Used only for washing over and cutting formation. Type J Cuts on the outside diameter and bottom. Does not cut on the inside diameter. The saw-tooth design allows maximum circulation. Used only for washing over and cutting formation. Type K Cuts on the bottom only. Does not cut on the inside or outside diameters. Used only for washing over and cutting formation.
