Retrospective Panorama On Application Of Restructured Rectorite In The Formulation Of Eco-Friendly Biodiesel Based Drilling Fluid

The uprising necessity for petroleum results in the swift evolution of drilling techniques in more complicated structure of wells and drilling operations under rough conditions. To meet this non-aqueous phase drilling fluids (NADF) is used to achieve good wellbore stability, thin filter cake, excellent lubricity and low risk of stuck pipe. The NADF is prepared by modification of bentonite with quaternary ammonium salts and addition of clay minerals. In this paper, a newly formulated environmental friendly restructured rectorite and biodiesel based drilling fluid is prepared and discussed.
