Universal Bottom Hole Orientation Sub
The Universal Bottom Hole Orientation (UBHO) Sub is used in a directional drilling BHA, and it is manufactured from high quality AISI 4145-modified fully heat-treated alloy steel or non-magnetic material like P530, P550 to provide a non-magnetic environment for drill string.
-
The UBHO sub is often referred to as a mule shoe sub. This tool is typically run directly below a drill collar and contains a landing sleeve for directional survey equipment. The UBHO is designed and used to establish the “high side of the tool”, which is essential for knowing the tools orientation in the wellbore.UBHO also stands for:
-
Universal Bent Sub Orientation;
-
Universal Bottom Hole Orientation;
-
Universal Bore Hole Orientation;
Various OD sizes are available to meet specific directional drilling applications. -

Top Drive Saver Sub
Top drive subs are a pin-by-pin sub that is made up to the top drive, they serve as the sacrificial element between the drill string and the top drive. This saves on costly repair to the top drive by allowing multiple connections to be made up and broke out using the sub rather than the top drive itself.¥ 0.00Details
-
Torque Reduction Sub
Torque reduction sub is to reduce the excessive torque generated by drilling in short radius horizontal section and large angle well section. According to its structural components, the torque reduction sub is divided into: mandrel body, upper and lower sliding bearings, slip spiral inner sleeve, straight rib outer sleeve, stop collar etc.¥ 0.00Details
-
Float Valve & Float Sub
API standard drill pipe Float valve is one of necessary tool for drilling, it consists of float valve sub and float valve, the main function are to prevent drill cuttings come into mud when connecting each joint and the bit bore block caused by back flow of silt.¥ 0.00Details
-
Crossover Sub
Crossover sub is a short sub assembly used to enable two components with different thread types or sizes to be connected. Also it can be used to protect other tooling in drill stem (called saver sub) or be used to deliver outgoing air to the bit face just above the bit (called bit sub).¥ 0.00Details
