Bio-Based Oil Drilling Fluid Improvements through Carbon- Based Nanoparticle Additives

Abstract

Performance issues of vegetable oil or bio-based oil drilling fluids are generally inferior as compared to synthetic based drilling fluids. This chapter focuses largely on thermal conductivity and rheological properties of bio-based oil drilling fluid as its core issues. Unstable drilling fluids do not only incur in downtime for maintenance, but it indirectly affects production capacity as well. To overcome these issues, nanoparticles acts as additives to improve the thermo-physical traits of bio-based oil drilling fluid. The scope of this chapter focuses on dispersion of graphene oxide at very low concentration, namely 25, 50 and 100 ppm, to improve the thermal conductivity and rheological properties of bio-based oil drilling fluid. The data obtained from thermal conductivity and rheological experimental works were validated with various thermal conductivity and rheological models.

Advances in Carbon Nanostructures and Nanocellulose as Additives for Efficient Drilling Fluids: Trends and Future Perspective—A Review

“…The literature shows that half of the present oil reserves stand 4200 m below sea level. The extreme HTHP conditions experienced in the borehole with temperatures of at least 300 °F (150 °C) and pressure of 10 000 psi or higher. , At such HTHP, drilling fluids can deteriorate and affect the production capacity in a negative way . To maintain the required features of the drilling fluid, various additives are introduced, such as polymers, surfactants, and barite. − However, the resulting drilling fluid remains unable to function under HTHP conditions and the cost of the drilling procedure also increases enormously.…”
