A Review Of The Effects Of Nanomaterials On Drilling Fluid Performance

Abstract
Maintaining the performance of drilling fluid throughout the drilling process is key to avoid problems that could jeopardize safety or budget of the operation. Projections of continued growth in deep drilling operations are pushing researchers and engineers to come up with a drilling fluid recipe that does not deteriorate under extreme conditions. In the twentieth century, extensive study has gone towards incorporating nanomaterials into drilling fluid in complex structural wells. In this paper, the effects of nanomaterials on drilling fluid, challenging scenarios, and possible implications are reviewed. The performance of drilling fluids improved in terms of fluid loss, lubricity, and rheological properties after nanomaterials were added. However, the yield point does not always improve and more study should be done on the electrical stability of the drilling fluid. Improvement of drilling fluids have grown tremendously in the past decade due to the presence of nanoparticles, however problems still arises when drilling in complex structural wells due to the uniqueness of each reservoir. Thus, more study should be focused on the different types of nanomaterials in drilling fluids to fully study its potential in the drilling industry to combat complex wellbore conditions.
