Drilling Tools International
Founded in 1984 and headquartered in Houston, Drilling Tools International (DTI) supplies the directional and horizontal drilling sectors through tool manufacturing, rental, and inspection. The firm operates as a publicly listed oilfield services company, with a commercial profile tied to the rig counts and completion techniques of major energy basins. The business rents and sells three main product families. Directional tool rentals cover stabilizers, drill collars, hole openers, and the ClearPath next-generation stabilizer series; wellbore optimization centers on the Drill-N-Ream wellbore conditioning system and the RotoSteer tool for extended-reach horizontal wells; and premium pipe rentals supply drill pipe, work strings, and blowout preventers. The firm also sells diamond products and downhole desanders, and runs an inspection division under Downhole Inspection Solutions. Geographic coverage spans all major US tight-oil and gas provinces — Louisiana, the Permian, the Rockies, the Marcellus — plus international service centers in Western Canada, the North Sea (Aberdeen), the Middle East (Dubai, Abu Dhabi, Dammam), the Netherlands, Germany, Malaysia, and Australia. DTI moved onto the public markets through a business combination with RCF Acquisition Corp in 2023; it trades on Nasdaq. In its most recent filing period it reported fourth-quarter and full-year 2025 results (per firm release, March 2026). The corporate structure houses multiple operating brands, including Deep Casing Tools and Stinger Oil Tools, and a Compass customer portal that allows registered operators to order and track tool orders digitally. The firm's architecture differs from a pure rental house. By controlling downstream manufacturing — steel and non-mag collars, PDC bits, and proprietary reaming technology — DTI can engineer tools directly against operator requests, with a product-development loop that runs from its Broussard, Louisiana plant through field trials in the Permian and Williston basins.

Frequently asked questions
Does DTI manufacture its own tools or function as a pure rental aggregator?
DTI controls its own manufacturing, notably through a facility in Broussard, Louisiana that produces steel and non-magnetic drill collars, stabilizers, and PDC diamond products. That captive production allows the company to engineer and test proprietary tools — such as the RotoSteer and Drill-N-Ream systems — directly with operator feedback, rather than relying solely on third-party OEM supply.
What distinguishes DTI's wellbore conditioning technology?
The Drill-N-Ream system is designed to eliminate dedicated reamer runs by conditioning the wellbore while drilling, which reduces torque, drag, and stick-slip. Its companion tool, RotoSteer, extends that capability specifically for longer-reach horizontal wells where traditional rotary steerable assemblies face mechanical limits.
Which basins and international theaters drive DTI's revenue?
The firm runs dense service-center coverage across the Permian (five Midland-area locations), the Gulf Coast (three Broussard sites), the Rockies, the Mid-Continent, and the Marcellus. Internationally, operations are weighted toward the Middle East — with hubs in Dubai, Abu Dhabi, and Dammam — and the North Sea via Aberdeen, complemented by facilities in Malaysia, Australia, Germany, the Netherlands, and Western Canada.
How did DTI become a Nasdaq-listed company?
DTI entered the public markets through a business combination with the special-purpose acquisition company RCF Acquisition Corp, with the transaction closing in 2023. That structure converted a legacy privately held oilfield tool rental and manufacturing business into a publicly traded entity.
Does DTI participate in upstream consolidation deals, or is it purely a product-and-services house?
DTI has grown partly through acquisition of adjacent product lines — Deep Casing Tools and Stinger Oil Tools operate under its umbrella — but the core model remains the manufacture, rental, and inspection of downhole tools rather than operating E&P assets or taking equity stakes in operators.
