RWSS Realtime Wellbore Strengthening

Vertechs RWSS technology is designed to provide a real-time enhancement of wellbore stability during drilling instable formations which are caused by 1) low formation pressure, 2) narrow drilling window, 3) fractured formation, 4) unstable formation, etc. Moreover, the patented on-site evaluation apparatus is the key to monitor & maximize the effectiveness of wellbore strengthening material. This field proven solution has been applied in various challenging wells and reduced NPT substantially related to wellbore instability and induced losses.
