NOVELTY - An inverse emulsion fluid comprises a dispersed phase comprising glycerol, or a mixture of glycerol and water, and a continuous phase including olefin, paraffin, mineral oil, vegetable oil, animal oil and ester. USE - Inverse emulsion fluid is used for offshore and on-shore drilling, completion, development, and production of natural resources, hydrocarbons, high temperature, high pressure, high slope and highly-reactive clays, potassium chloride, and other minerals from oil wells, gas wells, geothermal wells, directional wells (horizontal directional drilling), salt dome wells, and rock salt wells (all claimed). ADVANTAGE - The inverse emulsion fluid is a strategic fluid and environmentally-friendly, and has low toxicity, low bioaccumulation, and high biodegradability.
