Jun 12, 2017Some drilling methods use compressed air, which may also bring oil and contaminate the subsurface soil. The following are some common environmental drilling methods: 1.Hollow stem auger. Hollow Stem Auger (HAS) is the most common drilling method. HAS can be used to obtain continuous soil core samples.

Air rotary drilling is a method used to drill deep boreholes in rock formations. Borehole advancement is achieved by the rapid rotation of a drill bit which is mounted at the end of the drill pipe. The drill bit cuts the formation into small pieces, called cuttings. This method utilizes air as a circulating medium to cool the drill bit, bring

An apparatus associated with a drilling rig includes a surface steerable system for controlling drilling direction of a bottom hole assembly (BHA). The surface steerable system is configured to receive drilling rig parameters from the BHA. A database stores historical data related to the drilling rig. The historical data relates to previously tracked operations of the drilling rig.
