Oil and Gas Drilling

Hydrocarbons are extracted from the earth deposits via deep wells, both on shore and offshore. 

When a prospect location has been identified and evaluated by geologists, an exploration well is drilled in an attempt to conclusively determine the presence of oil or gas.

Different drilling techniques are used, depending on the underground formation and the well characteristics. In dry formations air/foam/mist drilling is the preferred drilling method.

The main reason for using air above conventional drilling fluids is to reduce the hydrostatic pressure in the wellbore (underbalanced drilling). High volumes of air clean the well bore of cuttings and drive the DTH hammer.
