CSG

Purpose: Complete lateral programme in depleted reservoir 

Project Description: 

  • Completion of 13 lateral wells 

Project Highlights: 

  • Work with Arrow to overcome challenges associated with drilling in highly depleted zones; 

  • Solve the challenges of providing well control on 45degree well entry;

  • Conventional MWD steering tools used to achieve desired well path;

  • Proved EM technology can be used within depleted coal seams.
