Abstract: Multi-component additive for incorporation into a drilling fluid, and a drilling fluid system comprising said multi-component additive. The additive preferably comprises three primary components: (1) a rate of penetration enhancer, namely one of a number of synthetic (non-toxic) ester-based or olefin-based oils as a carrier for other additives, such as surfactants; (2) a lubricant, namely one or more of a number of chlorinated waxes, chlorinated olefins, and plant based fatty acids; and (3) a clay inhibitor/stabilizer, such as a polyglycol. Preferably, the three components are pre-mixed in a single container, for ease in use in adding to a drilling fluid system. The additive may be incorporated into a drilling fluid system at a shore based facility, and the “liquid mud” transported to a drilling rig; or the additive may be brought to the drilling rig and incorporated into a drilling fluid system on site.
