Investigation Study of the Effectiveness of Eggshells Powder as a Multifunctional Eco-Friendly Additive in Water-Based Fluid


Utilizing the traditional chemical materials in the drilling process to modify the mud characteristics has led to many critical troubles, which are related to the environment and personal safety. That is why, researchers have been starting investigating alternative multi-use eco-friendly drilling fluid substances, which are generated from the edible waste products. The effectiveness of using two concentrations of eggshells powder (ESP) to spud mud was conducted utilizing typical API mud tests like filter press, viscometer, unpressurized mud balance, and pH meter. The findings revealed that ESP as an efficient substance to be invested as a weighting agent, viscosity elevator, and fluid loss control material. However, the results showed that ESP additives had no effect on the alkalinity by using 0.75% (5.25 gm) concentration and slightly reduced pH at 1.5% (10.5 gm) concentration. Moreover, increasing the concentration from 0.75% to 1.5% elucidated a sensible improvement in mud weight and the rheology, and inconsiderable enhancement in the filtration features. In summary, these promising experimental outcomes exhibit the feasibility for ESP to be used as a multipurpose biodegradable additive to reduce the drilling fluid expenses, minimize the side effects of conventional chemical materials on the environment and the drilling crew, and decreasing the volume of toxic waste disposed to the environment.
