Active Magnetic Ranging Services

Reduce uncertainty in wellbore positioning

Measure the distance and direction between two or more wellbores by using a field of known strength and orientation whether it’s generated with earth magnets or electromagnetism. With our active magnetic ranging services, you no longer need gyro surveys and you can:  

  • Drill safely when operating outside permissible anti-collision limits
  • Deploy parallel ranging accurately for maximized recovery in SAGD operations
  • Avoid well collision by acquiring precise positioning measurements between two wellbores  
  • Position wellbores within extremely tight tolerances, with a range distance of up to 262 ft/80 m, and eliminate costly sidetracks

Active magnetic ranging services include surface-access, access-dependent, and access-independent solutions.

Surface-Access Active Magnetic Ranging

Applications for parallel ranging without the need for downhole wireline conveyance, such as:

  • Steam-assisted gravity design (SAGD) environments 

Access-Dependent Active Magnetic Ranging

Applications where two or more wellbores are positioned within extremely tight tolerances, such as:

  • Stacked horizontal well pairs for SAGD wells
  • In-fill drilling and collision avoidance
  • Wellbore intersections for well control or pipelines
  • Observation well placement
  • Coalbed methane (CBM) degasification wells

Access-Independent Active Magnetic Ranging

Applications with no access to the existing wellbore but that require wells to be placed closely together without surveying errors, such as:

  • Relief well drilling
  • Collision avoidance
  • Enhanced recovery techniques (TAGD, SAGD, CBM)
  • Abandoned well identification and avoidance
  • Complex plug and abandonment
