Use of Tannate derived from Tea Waste as Drilling Fluid Additive

摘要

Excellent drilling fluid techniques are the significant guaranteed measures to insure safety, quality, efficiency and faster completion of drilling operations. However, after the completion of drilling operations these fluids become wastes and are discarded which can have a large negative impact on the environment. Both the drilling materials and additives containing drill cuttings, oil and water are dumped onto soil, surface water, ground water and air causing severe environmental pollution. The preservation of environment has become a major concern these days. Hence, this paper focuses on the use of calcium tannate as an environment friendly drilling fluid additive that is derived from tea waste obtained from tea industries using simple procedures. In this study, basically the rheological properties of the laboratory prepared drilling mud with and without adding calcium tannate have been determined and compared.
