Abstract

Nano-fluids show potential use in applications related to upstream oil and gas industry to improve the performance of several processes such as exploration, drilling and completion, production and enhanced oil recovery operations. However, their applications for water-based drilling mud (WBM) needs attention to address efficient drilling in a High Pressure and High Temperature (HPHT) environment. In the present work, nano-fluid-enhanced WBM (NWBM) are prepared using the nano-fluids of CuO and ZnO (size ˂ 50 nm) in a xanthan gum aqueous solution as a base fluid and used as an additive in WBM.

Highlights

Nano-fluids have recently attracted attention in the petroleum industry as potential solutions to several short comings of conventional drilling fluids [1]
The fluid was injected at a constant flow rate, in the opposite direction to oil production, at 200 psi
If used with high concentration with carbonates and with high pressure it can cause a huge fracture in the formation and as it holds its own proppant in nanoscale, it can be a suitable fracture fluid

Summary

Introduction

Nano-fluids have recently attracted attention in the petroleum industry as potential solutions to several short comings of conventional drilling fluids [1]. Drilling fluid is in charge of numerous functions during the drilling operation including transport of cuttings to the surface, maintaining the wellbore pressure and stability, lubrication and cooling of the drill bit and isolation of formation fluids by forming a filter cake around the borehole. Most troubles for some drilling issues are directly or indirectly triggered by fluid related problems including loss of drilling fluid and wellbore instability [2]. Nanoparticles are substances with dimensions in the order of 1e100 nm (nm). Nanoparticles have unique properties because their small size and greater surface area per unit volume; they show a more reaction with other molecules.
