RESUMO:

wo research fields are essential for the oil market these days: cost optimization and environmental issues. In the well drilling operations the fluid system is shown to be essential, and thus requires a continuous optimization. organic based drilling fluids are widely used in these operations, which, after use, become an expensive and polluting liabilities. Currently the treatment performed in this type of fluid is only correction, which usually requires large quantities of inputs, further increasing the cost of Fluid System for the drilling operation. Thus, the aim of this study was to develop a method of recovery of non-aqueous drilling fluids through the breaking of the water in oil emulsion using as agent de-emulsifying microemulsion systems. To obtain this microemulsion qualitatively studied the influence of different surfactants in the phase separation of the fluid and defined the best efficiency (RNX 95). For mapping of the fluid used in the tests were made rheology analysis, ratio of water / oil / solids, salinity, alkalinity, filtered and Electrical Estabildade. To study the emulsion breaking was varied: the composition dao microemulsion system for the RNX 95 tensaotivo, the aqueous phase of the microemulsion by using or not salt (CaCl2), the proportion of microemulsion / fluid system, the temperature at mixture. Test have also been made to the characterization of phases obtained after breaking test, as well as the possibility of reusing the non-aqueous fluid recovered. nonaqueous fluid recovered reuse tests had a satisfactory result.
