Operational excellence is our dedication. Therefore, we deliver the ultimate reliability and customer experience. As a company, we make it easy to do business.



Scientific Drilling International (SDI) is a prominent figure in upstream conventional reservoir drilling endeavors, boasting a leadership position in the industry for the past four decades. The reach of conventional reservoirs extends globally, with drilling activities onshore, on an inland barge, from an offshore shelf platform, deepwater floating platforms, ships, or semi-submersibles.

The wealth of experience gained over the years has propelled SDI’s innovative leaders to develop cutting-edge technologies to mitigate wellbore uncertainties and enhance drilling efficiency. At the core of their capabilities lies a robust and reliable survey system that provides a high-accuracy surveying system.

Our portfolio spans drilling single wells in remote locations and pad drilling across multi-well surface land. Leveraging our Measurement While Drilling (MWD) services and configuring them as a combo kit allows data transmission through either mud pulses or electromagnetic signals.



Scientific Drilling International (SDI) has played a pivotal role in exploring unconventional resources, particularly in North America, where we have successfully drilled over ten thousand directional and horizontal wellbores within the most significant shale deposits over the past decade. The service sectors for unconventional drilling covered by SDI include Shale, Tight Gas Sandstones, Heavy Oil, and Coalbed Methane / Coal Seam Gas (CBM/CSG).

Drawing upon our extensive experience in unconventional drilling, SDI contributes to advancing these resources. One notable achievement is the improvement of drilling rates while minimizing non-productive time, showcasing our commitment to efficiency in resource development.

Our suite of technologies, including Measurement While Drilling (MWD), Magnetic Ranging technologies, and innovative memory-based production logging services, extends its applicability to various heavy oil applications.


Traditional geothermal drilling environments pose unique challenges, given the complexities of corrosive rock, high pressures, and scorching temperatures that make deploying conventional downhole technology difficult.

With over 30 years of experience in the geothermal industry, Scientific Drilling International has been a critical player since its inception as a drilling service provider for UNOCAL in Indonesia. Over time, we have expanded our geothermal service portfolio from North and Southeast Asia to Australasia, Europe, Latin America, and the Western United States.

Our Success story includes drilling over 520 directional wells and completing over 1,150 production logging runs. These achievements stand as a testament to the reliability of our tools in the geothermal marketplace.

Our portfolio of technologies and services in this field encompasses:


For over 25 years, Scientific Drilling International has been a reliable drilling, survey, and logging solution provider to the global mining industry.  As a company, we have demonstrated success with projects spanning Canada and Russia, establishing ourselves as leaders in freeze-wall drilling applications for mining.

In the coal mining sector, the wellbores drilled by Scientific Drilling International play a crucial role in draining natural methane gas from the seam before long-wall mining. This process is essential for environmental conservation, preventing methane, considered 20 times more harmful than carbon dioxide (CO2), from venting into the atmosphere.

Scientific Drilling International employs high-accuracy rate-gyro surveying technologies for wellbores drilled in various mining scenarios. Notably, these technologies provide accurate positional data, leading to time and cost-saving benefits in coal seam gas drainage freeze-wall drilling projects.

The portfolio of technologies and services we offer include:


Scientific Drilling International (SDI) focuses on delivering downhole solutions. However, targeting the growing challenges of the global drilling and survey market.

For over 30 years, SDI has provided a suite of tools and services for civil engineering applications that include:

  • River crossing navigation
  • Industrial utility drilling and,
  • Construction drilling and surveying


Precise positioning of civil-engineered directional crossings is essential for public safety. Those involved should know how to locate existing underground utilities, survey tool selection, operation, and calculation methods. The directional drilling provider is often asked to install a new crossing. In short, close to a previously drilled installation. Thus, requiring detailed surveys to avoid a collision. Scientific Drilling International’s primary solution for Civil Engineering projects is the Keeper Gyro Survey Tool. The Keeper uses our patented multi-mode gyro survey system for high-accuracy surveying at all angles. Above all, the Keeper houses a unique continuous gyro navigation mode. Which allows for greater accuracy over conventional North Seeking systems. This configuration enables real-time gyro navigation during boring-oriented operations. It also provides the contractor with data to ensure the new installation is accomplished safely and without damage to existing utilities.

Scientific Drilling International recognizes the rising demand for greater control over wellbore placement, risk mitigation, and public safety across civil engineering projects worldwide. To that end, Scientific Drilling continues to improve their gyro technology and leverages our core business’s expertise to meet our customers’ growing demand.
