Abstract

Drilling industry is driving toward improving the performance of the drilling process in an economical and environmental attractive way. Recently, drilling development techniques faced greater challenges in terms of wellbore stability as polymers with different salt concentrations, have major effect on the drilling mud properties. The rheological behavior of several polymers used effect on common types of mud with different salt concentrations, that change normal mud properties (plastic viscosity, yield point, gel strength, API filtration). Exposing to different concentrations require utilizing polymers additives in order to avoid high cost and nonproductive time. The present work tested the effect of three different salt concentrations on mud polymers during drilling operations
