David Colton,Rainer Kressis considered. The mud sample is formulated and the filtration characteristics of the mud samples were estimated using a Low Pressure Low Temperature (LPLT) filter press in accordance with the API-recommended practice for field testing for Water-based muds. The results revealed that the pine needle
