Abstract: To enhance the resolution of hydrocarbon reservoir characterization, the deployment of super-paramagnetic iron oxide nanoparticles (nMag) was investigated. In this work, laboratory-scale experiments were performed to quantify the transport behavior of nMag in various types of porous media under high-salinity conditions. Analysis of effluent and solid phase concentration data indicated th... read moreat nMag exhibited a limited solid-phase retention capacity, which was dependent upon grain size and pore-water velocity. The use of polymers or surfactants injected either prior to, or with the nMag injection, resulted in further enhancements in nMag mobility. This behavior was attributed to site blocking, in which the surfactant or polymer, preferentially adsorbs onto the attachments sites, thereby limiting nMag interactions with the solid phase. This work provides experimental data that can be used to improve down-hole delivery of nanomaterials for reservoir characterization, and support the development and validation of predictive models for field-scale applications.
