Core Drilling in Permafrost Oilfields: Special Considerations-Rig

Permafrost oilfields (frozen ground) need special core drilling approaches.rig
  1. Insulated Drill Strings: These keep heat in, preventing ice from forming around the drill. This avoids stuck pipes.
  1. Low – Temperature Fluids: Drilling fluids must work below freezing. Special mixtures prevent them from turning to slush.
  1. Rapid Core Freezing: Cores from permafrost must stay frozen. This preserves their original properties for testing.rig
The Arctic holds vast oil reserves. Core rigs adapted for permafrost make exploring these areas possible. They let teams work in some of the coldest places on Earth.
