Abstract. Application of nanotechnology in drilling fluids for the oil and gas industry has been a focus of several recent studies (Zakaria et al. 2012; Contreras et al., 2014). Zakaria et al. (2012) developed a process for the in situ synthesis of nanoparticles (NPs) and reported that calcium-based and iron-based nanoparticles (CNP and INP, respectively) with concentrations of 0.5-2.0 wt% can dramatically improve filtration properties of commercial drilling fluids in a lab environment. A modified process for the emulsion-based synthesis of NPs on a large scale has been developed and a NP carrier fluid was employed in full scale field tests. Results showed that total mud losses while drilling with CNP-based invert emulsion were on average 27% lower than in the case of conventional fluids, which falls within the range seen in the laboratory.
