RESUMO

Cased well logging with tools which quantify the water saturation had been done in the Study Field, located on Recôncavo Basin, considered mature and with reminiscent hydrocarbonates storage in the Sergi Formation. The geostatistical techniques of ordinary kriging and kriging with external drift had been used to the studied field for porosity and water saturation of development model. The results of the modeling of water saturation variable in steps of time allowed to characterized the evolution of the water saturation in the field and the identification of the remaining oil portions. With information models of petrophysics and the fluids saturation , the oil volume calculus for the three temporal intervals analyzed had been done. Values had been obtained which allowed proving the dynamic of Sw variable along the years and verifying the reminiscent oil in the reservoir
