Shale gas reservoirs vary greatly in depth. Different
rigs suit different depths, with distinct features.rock core drilling rig
-
Shallow shale (<1,000m): Use light rigs. They move easily, operate simply, cost less, and finish shallow coring fast.
-
Medium-depth shale (1,000-3,000m): Medium rigs work better. Their power and drilling capacity balance quality and efficiency.
-
Deep shale (>3,000m): Heavy rigs are needed. They have strong power and pressure resistance, handling deep complexity for quality cores.
Choosing rigs by depth optimizes resources, enhancing shale gas development economics.
