Abstract:
This invention describes the development of technology for the preparation of superparamagnetic lipophilic nanofluids, as well as of drilling fluid additives based on the aforementioned nanofluids, which improve the properties which form walls or mud filter cakes and concomitantly act as contrast agents in RMN logging.
