Shale gas reservoir geology is complex; choose rig types based on specific conditions.rock core drilling rig

 

  1. Surface rock core drilling rig: Fit shallow shale exploration. They’re easy to operate, mobile, get shallow cores fast, with lower costs.
  2. Deep rock core drilling rigs: Target deep-buried shale. They have strong power, drill deep, withstand high pressure, securing quality cores below 1,000 Metros.
  3. Continuous coring rigs: Take cores non-stop, reduce gaps. Ideal for analyzing shale continuity, aiding precise fracturing designs.

Proper rig selection boosts efficiency, cuts costs, laying groundwork for smooth shale gas development.
