Geo Tec represents Air drilling. Air Drilling Associates is a world leader in applying air-, mist-, foam-, aerated fluid and other underbalanced techniques for petroleum and geothermal drilling projects.
1. Mist Drilling
Mist Drilling is used when the rock formations begin to produce small amounts of water (10 to 100 bbls per hour) during air drilling operations. Air volumes are increased and a Mist Pump is used to inject small quantities of a solution of water and foaming agent.
2. Foam Drilling
Foam Drilling is especially suitable for drilling large holes in formations that are prone to lost circulation. Foam is generated at the surface by mixing the air from the compressors with a foaming solution from the mist pump.
