Abstract: A composition is described comprising an organic polymer or a polymerizable monomer, having dispersed therein a surface-modified particle phase, in an amount sufficient to reduce the flammability of the polymer.
Abstract: The present invention provides a drilling fluid composition and a method of drilling comprising a drilling fluid, which may be oil- or water-based, and a composite microsphere component. The invention drilling fluid composition advantageously reduces the density of a conventional fluid, reduces costs associated with pumping and overcomes problems associated with conventional gas-injection processes. The invention uses conventional drilling and pumping equipment, requires no sea-floor based pumps and may be easily pressure-controlled to maintain the pressure of the fluid.
