Deep Sea Rock Drill Fluid Improved Performance by Addition of Nanomaterials

Abstract

This review contains descriptive issues about improvement in bentonite-based drill fluid after nano matter addition applicable to oil and gas well. This is to improve high-temperature access as well as viscous-dynamic performances under low fluid loss. Oil-based drill fluid seemed to be more favorable as restrict seal by mud cake containing shale whereas water-based drill fluid is economical and ecofriendly. Shale of mine is often searched as the sacred source of oil and gas called shale gas. Waterbased drill fluid added with nano particulates of carbon and metal oxide has improved rheological characteristics. Local particle formation of varying sizes is inclusive to involve permeability differences to filter out fluid from wellbore walls to induce sticking defect by thicker mud. Shale constructive by the seal of nanoparticles of proper compose has suggested inclusive as the solid reservoir of oil and gas, lubricant and ingredient to maintain the stability of wellbore. Accessible properties are studied on the ability to withstand harsh borehole conditions, the extension of the life of downhole tubes and drill bits, expansion of tubes for deeper wells without a telescope, cement integrity for quality placement of oil and gas well, used to be active drill motors and tooling. An additional aim is the usage of miniaturized electronics, higher-density batteries for small drill microholes, and suggested improvements in drill fluid to reduce mud invasion.
