Bentonites are selected for each industrial need on the basis of type and quality. This selection is based principally on physical properties, and chemistry of the bentonite becomes involved only to the extent that it influences the physical properties. Drilling fluids are used in drilling operations to cool and lubricate the drill bit, remove rock debris and drill cuttings from the site and to counteract down hole for- mation pressures. Research is being conducted to develop nanoparticle-amended drilling fluids with enhanced functionalities. Such enhancements include improved rheological, thermal, mechanical, magnetic and optical profiles. These drilling fluids will have close to real time responsiveness (for example viscosity) to changing conditions down hole. Researchers at the National Energy Technology laboratory are designing an environmentally-friendly nanofluid for oil and gas exploration and drilling that can withstand the high temperatures and pressures in deep and horizontal drilling operations. To tackle the challenge of controlling the rheological profile of drilling muds in situ in response to changing environmental conditions down hole, super paramagnetic iron oxide nanoparticles are being added to create drilling fluids with viscosities that can be rapidly altered in situ by applying a magnetic field. Similarly, the addition of carbon nanoparticles is effective at controlling the viscosity of drilling muds. The addition of nanoparticles to drilling muds can also be used to remove the highly toxic and corrosive Hydrogen sulphide gas that diffuses into drilling fluids during drilling operations.
