Effect of CuO and ZnO nanofluids in xanthan gum on thermal, electrical and high pressure rheology of water-based drilling fluids

TL;DR: In this article, a nanofluid-enhanced water-based drilling mud (NWBM) was used to address efficient drilling in an HPHT (High Pressure and High Temperature) environment.
Journal ArticleDOI

Formation and characterization of thermal and electrical properties of CuO and ZnO nanofluids in xanthan gum

TL;DR: In this paper, the thermal and electrical conductivities of zinc oxide and copper oxide nanofluids with varying concentrations of nanoparticles (0.1, 0.3, and 0.5 ) were analyzed using a scanning electron microscope and dynamic light scattering (DLS) method, respectively.
Journal ArticleDOI

Friction factors: What are they for torque, drag, vibration, bottom hole assembly and transient surge/swab analyses?

TL;DR: The term "mechanical friction factor" has been used for fluid flow engineering calculations in the drilling industry as discussed by the authors and is used as a proxy for the coefficient of friction (COF) or the Coulomb friction, a dimensionless scalar value, in the estimation of torque, drag, and side forces.
