The water loss from the drilling fluid with the addition of natural additives like bagasse, natural sugar, and natural rubber was studied. The entire study is focused on improving the quality of controlling fluid loss with the effect of natural additives. The concentrations of the additives were changed to achieve the desired reasonable value of fluid loss with the help of high pressure and high temperature (HPHT) filter press which worked at the condition of 500 psi and at 300oF temperature. Rheology and various tests of these different samples were studied, and the result is tabulated in this article.
