Scientific Drilling's Surveying Systems provide a dependable and competitive service, facilitating faster drilling operations while enhancing confidence in the process.

Electronic Multi-Shot (EMS)

Scientific Drilling International offers the Electronic Multi-Shot System (EMS), utilizing the high-accuracy magnetic survey package found in our MWD systems. Specifically designed for use with non-magnetic collars, the EMS conducts surveys during a trip out of the hole. With substantial onboard memory, it enables survey runs in long hole sections.

Furthermore, the EMS system is available in a high-pressure and high-temperature (HPHT) version, ensuring 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 (MSS) offers unparalleled reliability in the most challenging drilling conditions and supports a wide range of running gear structures.

Key features include a 1″ O.D. solid-state downhole probe equipped with a sensor package. This package comprises tri-axis flux gate magnetometers and tri-axis fluid-dampened accelerometers, providing comprehensive all-attitude survey and steering capabilities.

The transmitted data includes essential survey information, continuous tool face, individual sensor outputs, temperature, total magnetic field strength, and total gravity field strength. Steering and surveying information is promptly transmitted to the remote drill floor data, ensuring real-time access.

MaxFlow Landing Ring


Scientific Drilling International introduces the MaxFlow Landing Ring (MFLR), an innovative system designed for conducting Drop Keeper Gyro surveys in drilling assemblies. This system is particularly useful in scenarios where ball-activated reamers, PBL subs, or wireless pipe recovery systems are needed.

MaxFlow is characterized by a distinctive landing ring and bullnose combination. Unlike traditional baffle plates, it is engineered to maximize the flow area while ensuring high circulation rates. This design enhances borehole stability, well control management, and allows the passage of standard drop ball sizes.
