Abstract
The present invention relates to an improved continuous phase for a drilling fluid and specifically a silicone continuous phase which is non-polluting and substantially non-toxic. Preferred silicones for use in the invention are dimethylsiloxane polymers. In the drilling fluid compositions, suitable emulsifiers, wetting agents, viscosifiers, weight materials and fluid loss additives may be added in conjunction with water and/or a brine phase for desired rheological properties.
