Scientific Drilling International

What Scientific Drilling International does

Scientific Drilling International (SDI) is an independent, privately held directional drilling and wellbore navigation service company founded in 1969 and headquartered in The Woodlands, Texas. The company designs, manufactures, and operates a full stack of directional drilling technologies in-house down to the sensor level, including drilling motors (TiTAN22, TiTAN HD), rotary steerable systems (HALO), mud pulse and electromagnetic MWD platforms (Falcon X, Falcon), solid-state and spinning-mass gyroMWD systems (URSA, Keeper), logging-while-drilling tools, magnetic ranging systems (MagTraC, Lodestone, BlackShark, MagTracer, PunchOut), and cased hole services (MPNN pulsed neutron, Vulcan flow logging and multi-finger calipers). SDI holds more than 50 issued and pending patents and operates three R&D centers in California, Texas, and Germany, employing over 80 scientists, engineers, and technicians.

The company generates revenue through a combination of professional services (directional drilling, surveying, cased hole evaluation, and survey management) and proprietary hardware sales/leasing, deployed via a direct enterprise field-sales model through a global network of nearly 40 district offices, operations bases, motor service facilities, and technology centers spanning North America, Latin America, Europe/Africa, the Middle East/CIS, and Asia Pacific. End customers span oil & gas (both conventional and unconventional, including shale, tight gas, heavy oil, and CBM/CSG), geothermal, mining, and civil engineering sectors. In January 2024 SDI acquired the DynaView data platform from Tally Energy Services, adding real-time wellbore planning and monitoring analytics to its service offering and signaling a strategic shift toward software-enabled, remote operations models such as zeroPOB.

Core offering

Scientific Drilling International provides directional drilling and wellbore navigation services for oil and gas, geothermal, and mining industries worldwide. The company designs, engineers, and manufactures its own MWD/LWD systems, rotary steerable systems, drilling motors, gyro surveying tools, magnetic ranging systems, and cased hole evaluation tools, deploying them via field crews to deliver integrated drilling services to operators globally.

Product overview

Scientific Drilling International offers a comprehensive portfolio of wellbore navigation and directional drilling technologies, positioning itself as the only company providing a complete navigation solution for the energy services sector. The product portfolio centers on in-house designed, engineered, and manufactured directional drilling and wellbore navigation technologies, including Drilling Motors (TiTAN22, TiTAN HD), Rotary Steerable Systems (HALO RSS), MWD Systems (Falcon X, Falcon, Deep EM Receiver), gyroMWD solutions (URSA, Keeper), Logging While Drilling tools (Natural Gamma Ray, Azimuthal Gamma Ray with BitSub/Smart Motor, Resistivity Solutions, Pressure While Drilling), Wellbore Surveying systems (ATLAS, EMS, Keeper Gyro tools), Magnetic Ranging services (MagTraC, Lodestone, BlackShark, MagTracer, SynTraC), and Cased Hole Services (MPNN, Vulcan FLS, Vulcan MFT). The TiTAN motor series pairs with the HALO RSS for complete BHA configurations, while gyroMWD technologies integrate with MWD/LWD systems from leading directional providers. The URSA and Keeper gyroMWD systems offer modular compatibility with third-party MWD systems alongside SDI's own Falcon telemetry platforms. Cased hole evaluation tools including the Vulcan series of flow logging systems and multi-finger calipers round out the comprehensive wellbore lifecycle solution.

Broad incumbents

• Halliburton / Sperry Drilling: Largest integrated directional drilling and MWD/LWD provider globally, operating as a division of Halliburton. Directly overlaps SDI's MWD, LWD, and rotary steerable offerings but bundles them with broader drilling, completions, and digital services — competing on integrated tenders where SDI bids as a specialist.
• Schlumberger / SLB: Global OFS major with a leading directional drilling and wellbore positioning portfolio (PowerDrive ICE, Teleo, PeriScope). Overlaps SDI's MWD, LWD, rotary steerable, and gyro surveying capabilities but as part of a much larger integrated offering across drilling, evaluation, and production.
• Baker Hughes: Major OFS provider with significant directional drilling and MWD/LWD capability (including the historical SDI technology center alumnus Gerald Heisig who joined SDI from Baker Hughes). Overlaps SDI's rotary steerable, MWD, and drilling motor businesses at a global integrated scale.

Direct peers

• Weatherford International: Large independent OFS provider with directional drilling, MWD/LWD, and downhole tooling capabilities. SDI's CFO finance director previously worked at Weatherford (West Africa Controller), and Weatherford is a relevant comparable in directional drilling and drilling motor segments.
• Gyrodata: Specialized wellbore surveying and gyro-while-drilling service company, directly competing with SDI's Keeper and URSA gyroMWD product lines. Most closely comparable as a directional surveying specialist focused on magnetic interference environments.
• APS Technology: Provider of MWD/LWD sensors, drilling electronics, and downhole instrumentation. Directly comparable to SDI's LWD portfolio (gamma ray, azimuthal, resistivity) and competes in measurement-while-drilling technology for oilfield and HDD applications.
• Nabors Industries: Drilling contractor and downhole technology provider with directional drilling, MWD/LWD, and drilling motor offerings (Nabors subsidiary ReedHycalog and Canrig). Comparable in drilling motor and rotary steerable segments, particularly in US land.
• Probe Holdings: Provider of wellbore cleaning, fishing, and specialty downhole tools, with directional drilling service offerings. Comparable to SDI in providing wellbore intervention and specialty directional services for oil & gas operators.

Emerging players

• McCoy Global: Provider of tubular running services and downhole tools for oil and gas and adjacent industries. Comparable to SDI's cased hole and downhole tool businesses but with a smaller and more focused product portfolio in running tools rather than full directional drilling systems.

Regional players

• Vermeer Corporation: Manufacturer of horizontal directional drilling (HDD) equipment and tooling for utility, pipeline, and civil construction. Comparable to SDI's PunchOut HDD guidance solution and broader HDD market, though operating primarily in non-oilfield HDD verticals.
