Scientific Drilling's Surveying Systems deliver a reliable and competitive service. Thus, enabling faster drilling operations with improved confidence.

Electronic Multi-Shot (EMS)

Scientific Drilling International provides an Electronic Multi-Shot System (EMS). This system uses the same high-accuracy magnetic survey package as our MWD systems. For example, it is designed to be run with non-magnetic collars. In addition 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. Therefore, delivering 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 most demanding drilling conditions. It also supports a wide range of running gear structures.

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

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

MaxFlow Landing Ring


Scientific Drilling International’s MaxFlow Landing Ring is an innovative system. This system enables Drop Keeper Gyro surveys in drilling assemblies. Moreover, this is where ball-activated reamers, PBL subs, or wireless pipe recovery systems are required.

MaxFlow features a unique landing ring and bullnose combination. In other words, it is engineered to replace traditional baffle plates and maximize the flow area. Meanwhile, maintain high circulation rates, ensuring optimal borehole stability, well control management, and pass-through of standard drop ball sizes.
