Scientific Drilling International is an independent directional drilling and wellbore navigation, surveying and logging service company serving customers worldwide.

Scientific Drilling International was founded in Houston, TX in 1969. Since then, our company has grown to be a leading provider in the global wellbore navigation services market as well as the US directional services market.
Our presence reaches over 26 countries and nearly 40 locations, being the only company to offer a complete navigation solution for the energy services sector that includes High Accuracy Gyro Survey, MWD, LWD, MagTraC MWD Ranging™, and Cased Hole Solutions.

Scientific Drilling International serves a diverse range of customers in all energy sectors. Besides participating in some of the most complex conventional and unconventional oil and gas projects in the world, Scientific Drilling also has extensive experience in working on geothermal wells and drilling horizontal laterals in coalbed methane reservoirs.

HISTORY OF FIRSTS

When the phrase “Scientific Drilling” was coined, sometime after World War II, it conjured up the notion that independent scientists could probe the earth’s depths to learn more about the nature of this planet and how its resources developed.

In 1969, James Murray, an engineer living in Houston, TX launched a technology company.  He wanted to use the latest scientific drilling practices and navigation solutions to help oil and gas producers, miners, and geothermal companies plumb this planet’s depths for new reserves.  Aptly, he named the company Scientific Drilling Controls (SDC).

Murray soon introduced the world’s first downhole electronic steering tool (called “the Eye”) to enable directional drillers to accurately orient downhole motors to deviate wellbores.  Building upon its earliest triumphs, in 1977 SDC introduced the world’s first surface readout gyro (SRG) tool, then in the 1980s, launched directional drilling and specialized north seeking gyros.

In 1986, Don van Steenwyck, a World War 2 veteran (Navy) and electronics engineer, owner of California based Applied Technologies Associates (ATA), acquired SDC to be the execution arm of his engineering designs and concepts in wellbore navigation and real-time communications while drilling.  Scientific Drilling International (SDI) was formed!  With his guidance, the company would grow immensely and prosper, continuing to deliver cutting edge technology to the industry.

Fast forward to 2017, and SDI, under strong leadership, has a vision “to become the ultimate partner in wellbore placement and productivity around the world.”  It continues to produce innovative and robust technologies that deliver the ultimate value in accuracy, living up to the founder’s dream.  SDI is dedicated to its employees, without whom, none of these would have been achieved.
