INVERT EMULSION DRILLING FLUIDS WITH FATTY ACID AND FATTY AMINE RHEOLOGY MODIFIERS

摘要

Various invert emulsion drilling fluid compositions. One such invert emulsion drilling fluid is a water in oil emulsion, which can include an invert emulsifier to stabilize the water in oil emulsion, a fatty acid, a 36 carbon fatty dimer diamine, a filtration control agent; and an inorganic mineral including one or more of lime, calcium chloride, and barite. The invert emulsion drilling fluids can be formulated to be substantially free of clay.
