Research Center of the Escola Politécnica - USP, focused on the interdisciplinary science and technology, combining research and innovation activities with the development of human resources. InTRA brings together innovation and scientific rigor in its activities, always seeking quality and efficiency in the construction of knowledge related to the oil and gas sciences. Some analytical routines that support our activities: - Basic Core Analysis: porosity, pore volume and permeability; - Special Core Analysis: wettabillity (contact angle at reservoir condition and Amott/USBM); - Fluid Analysis: chemical characterization of oil, total acid number (TAN), organic compounds identification, determination of chloride concentration in brines, asphaltenes inhibitors evaluation.
