Scientific Drilling's Surveying Systems deliver a reliable and competitive service which enables faster drilling operations with improved confidence.

Electronic Multi-Shot (EMS)

Scientific Drilling International provides an Electronic Multi-Shot System (EMS) which uses the same high-accuracy magnetic survey package as our MWD systems. This system is designed to be run with non-magnetic collars to survey during a trip out of the hole. The EMS features substantial onboard memory allowing survey runs in long hole sections.

The EMS system is also available in a high-pressure and high-temperature (HPHT) version. It delivers optimal performance in temperatures up to 600°F (315°C) and bottom-hole pressures up to 33,000 psi.

Magnetic Steering System

The Electronic Magnetic Steering System provides the ultimate reliability under the harshest of drilling conditions and supports a wide range of running gear configurations.

It features a 1″ O.D. solid-state downhole probe with a sensor package of tri-axis flux gate magnetometers and tri-axis fluid dampened accelerometers, providing an all-attitude survey/steering capability.

Data transmitted includes the required survey information, as well as continuous tool face, individual sensor outputs, temperature, total magnetic and total gravity field strengths. Steering and surveying information is instantaneously transmitted to the remote drill floor readout.


Scientific Drilling International‘s wellbore surveying technology has been streamlined to provide customers with the new EDGE Survey System. EDGE provides a cost-effective option for appropriate markets, while maintaining the performance and quality standards customers have come to expect from Scientific Drilling International.
