Laboratory research on the influence of new BG-027 polymer addition on technological parameters of drilling mud dedicated to directional drilling in shale rocks

This paper shows the research results on the influence of new BG-027 polymer used in different concentrations onto technological properties of drilling mud for drilling in shale and clay rocks. Standard API test has been conducted as well as thermal resistance, resistance to mono- and divalent sa lts, LST were studied. The results show that polymer BG-027 addition gives the mud good technological parameters and is a good hydration inhibitor.
