Rheological evaluation of Mucuna solannie for non-aqueous mud additive in drilling operations

Abstract

Mucuna solannie is a Papilionaceace used in culinary. Its rheology using API specifications was evaluated. Compared with Carbogel,  plastic viscosity of 17 against 16cP at 8ppb, yield point of 27 against 26 lb/100ft² at 2ppb, 10 minutes gel strength of 17 against 15 lb/100ft² at 6ppb, annular flow index of 0.46 against 0.42 at 8ppb, annular consistency index of 44.6 against 30.6 eq-centipoise at 2ppb, pressure drops of 10.43psi against 8.60psi at 2ppb, and cutting concentration of 1.272 vol. % against 1.215 vol. % at 8ppb were obtained. The results showed it has nano- particles
