NOVELTY - A microemulsified fluid formulation comprises, in a continues phase, a mixture of 1-10 wt.% fatty acid of oil of animal origin with 1-80 wt.% fatty acid of oil of vegetable origin, or 1-90 wt.% fatty acid of oil of vegetable origin, in liquid form. USE - Microemulsified fluid formulation is used for drilling offshore (maritime) or onshore (terrestrial), completion, development, and production of fluids for oil wells, gas wells, geothermal wells, directional wells (horizontal directional drilling), saline dome wells, rock salt wells, potassium chloride wells and other minerals, their derivatives, or even natural resources (all claimed). ADVANTAGE - The microemulsified fluid formulation is non-toxic and biodegradable, and does not require temperature in its manufacture either in probe onshore or offshore, that is, the ambient temperature is enough for manufacturing fluid on an industrial or laboratory scale.
