For the purpose of flow assurance, (i) use of nanoparticles for wettability alteration near wellbore; (ii) nanoparticle-based placement of scale inhibitor chemicals into the reservoir; and (iii) use of magnetic nanoparticles for localised heat generation.
In addition to the nano-enhanced metallic alloys, new developments in nano-enhanced polymers and elastomers (such as sealers) that can withstand the harsh downhole conditions and provide long-term reliability for their required function; and nano-coatings to the tubular goods and surface facilities that provide low friction, and resistance to corrosion and abrasion.
Current state of research and development for improved characterisation of asphaltenes in reservoir and produced oil, considering nano-structural aspects and employing the tools of nano-science and technology. Improved monitoring of the asphaltene dynamics in the reservoir and at the wellbore and pipelines, and their management for improved oil production and field operations.
Methane hydrate receives attention as one of the unconventional gas resources in the future. On 12 March 2013, JOGMEC accomplished to produce methane gas from methane hydrate layers in Nakai Trough. How the nanotechnology will contribute in the production phase, such as CO2 replacing the methane from hydrate and at the same time sequestering the CO2 by addition of nanoparticles for the flow assurance during the gas production, and improving the energy efficiency.
Current state of research and development to better characterise the hydrocarbon contents of shale pores and their dynamics, employing the nanoscience and nanotechnology tools, such as FIB-SEM, X-Ray Nano-CT, AFM, QCM-D, NMR and others. Chemical models for kerogen and its nano pores from analytical experiments. Development of next generation Shale-Gas/Oil-Reservoir Flow Simulators.
Low-salinity EOR is recently attracting considerable attention because of its low cost and ease for field implementation. Although some physical and chemical mechanisms of improvements by low-salinity water have been proposed, no consensus has yet been established. Nano-technology and nano-geoscience can help understand the mechanisms and design an appropriate recipe of water constituents. Additionally, desalination is important to practically apply to oil reservoirs. Efforts have been made to produce sufficient low-salinity water by employing nano-filtration, magnetic nanoparticle dispersions, and etc.
Nanotechnology is being utilised in ever increasing degree in virtually all industries, for medical sciences, electronics and consumer products to the E&P industry. These materials have the potential to be very beneficial from the environmental point of view, such as in CCS and gas separation applications, etc. On the other hand, there is a growing body of literature that indicates these materials require special environmental and health screening to ensure the safety of all who come into contact with them. This session will examine the uses in CCS, gas separation, etc. as well as outline regulatory requirements in the EU and elsewhere.
