UNSPSC 71121644: Directional drilling bottom hole assembly

A bottom hole assembly (BHA) is a component of a drilling rig. It is the lowest part of the drill string, extending from the bit to the drill pipe. The assembly can consist of drill collars, subs such as stabilizers, reamers, shocks, hole-openers, and the bit sub and bit. Equipment service assembly includes a mud motor, directional drilling, and measuring equipment, measurements-while-drilling tools, logging-while-drilling tools, etc.

UNSPSC 71121644 Directional drilling bottom hole assembly is a Commodity code that describes specialized drilling components and equipment used in oil and gas exploration and extraction operations. State and local governments purchasing under this code procure drilling equipment and related tools for infrastructure development, particularly in energy, water well, and geothermal applications where directional drilling capabilities are required. Recent solicitations show state procurement offices, corrections departments, and cooperative purchasing entities acquiring drilling rigs, crawler-mounted derricks, and associated drilling assemblies through competitive bidding processes.

The Texas Department of Criminal Justice (TDCJ) and the State of Texas dominate recent activity under this code. TDCJ issued IFB IW256901-A for a Derrick Digger Crawler with responses due August 31, 2026, procured through the TDCJ Procurement Portal and managed by procurement officer Ronald Schlenker. A parallel State of Texas IFB (IW256901) closed July 16, 2026, covering equipment and services for derrick digger procurement, though detailed scope and specifications were not disclosed in the solicitation summary. Sourcewell, a Minnesota-based cooperative purchasing entity, posted RFP 061626 (due June 16, 2026) for law enforcement equipment on behalf of participating entities in Washington state counties including Franklin, Grant, Grays Harbor, Chelan, and Yakima, though this opportunity appears unrelated to the directional drilling focus of the underlying UNSPSC code and likely represents a tagging mismatch. Texas constitutes the primary recent procurement activity under this code, with opportunities concentrated in state-level equipment acquisition through IFB processes.
