Filtration control characteristics of the mud samples were demonstrated by the filtrate volume and mud cake. After 30 minute of filtration, base mud and drilling mud with LA-GLG concentration of 1.0%at temperature 30˚C produced 12.5ml and 7.5ml respectively. After boiling mud sample until the temperature 80˚C filtration of both mud samples produced 16.7ml and 7.3ml. LA-GLG has the ability to develop rheology properties and filtration control despite the increase in temperature.
