Laboratory investigation of invasion control by novel polymeric drilling fluid system

The ability to reduce the invasion of filtrate to the lowest possible level has many advantages consists of less formation damage, less differential sticking and the prevention of somekinds of mechanical instability. It is not surprising therefore that, in recent years, a considerable amount of effort has beenexpended in trying to find zero fluid loss fluids . In this research study was described the materials and methods used such as hydrophobic modified polymers toproduce a new polymeric drilling fluids system. The paper then presents experimental results of laboratory data on invasion control, formation damage and differential sticking. [1, 3]
