Rotary Magnetic Ranging System



The RMRS kit, which has been widely used in well intersections for its high pinpoint accuracy, mainly consists of a Rotating Magnet Sub, a RMRS Sensor Probe ,a surface controller and data software.


● High pinpoint accuracy for artificial magnetic field

● Single cable simplify equipment operation

● Small size sensor probe can be used in most well


● U-shaped coalbed methane well

● Water-soluble mining well

● Obstacle avoidance drilling of geological exploration wells

● Steam assisted gravity production parallel well control

● The ventilation shaft connected with roadway

● Ultra-deep trenchless well
