SDI 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.
