A drilling fluid contains caustic, a natural wax, a natural thinner, glycerol, phosphoric acid and/or boric acid, and optionally a gel. The drilling fluid can be prepared in modules. Each module contains additional compounds to improve or change the action of the drilling fluid depending on the condition found in the field. The drilling fluid adjusts the properties of conventional drilling muds including increasing lubrication, thins the drilling mud, decreases bit balling, decreases rock resistance and controls phase separation of the drilling muds. |
