HDD Intersections
The RMRS system has been used for over 200 successful intersections. RMRS is a robust and accurate system, giving precise target information at greater than 140 foot range.
A frequent application of the Rotating Magnet Ranging System is an intersection between a horizontal well and an existing well. The magnetic bit sub is located directly behind the drill bit and the receiver on wireline in the target well. Accurate position information can be acquired at more than 120 feet of lateral separation, allowing for significant trajectory correction prior to intersection.

The Map view illustrates typical ranging points while drilling the horizontal well. The triangles are coordinates of the bit as drilling progresses; arrows are the projected azimuth of the drill bit. The green circle indicates expected target location based upon gyro surveys. The blue circle is the actual point of intersection. Red X’s are the coordinates of the vertical well as surveyed by the Rotating Magnet Ranging System.
