Early Warning System (EWS)

Sperry Drilling services' EWS system, which contains the CFM connection flow monitor system, plus an early warning of abnormal conditions while drilling or circulating was developed to allow rapid response to any unpredicted change in the mud flow or standpipe pressure. While designed to allow early warning of a kick or loss of returns, the system has also been shown to be helpful in warning about washouts and other mechanical problems. An easy-to-read traffic light alarm system can be installed on the rig floor. Moreover, because the EWS system is based on the InSite® system, it is also possible to install a full monitor or explosion-proof workstation on the drill floor. These screens can be used to show both the trend analysis and the alarm conditions.
