Abstract

Historical events and recognition of the potential hazards caused by the adverse production environment (such as high pressure and high H2S) of existing wells in Tengiz and Korolev fields has led Tengizchevroil (TCO) to always be focused on risk mitigation and safety procedure and fully aware of the criticality of well integrity. Thus, appropriate and robust processes were developed early in the field development as a precationary step to mitigate the risk of potential well failure events. These processes later evolutioned into fully documented, automated, robust TCO Well Integrity process, which meets both industry API RP standards, Chevron Process Safety guidance and Kazakhstan’s Industrial Safety Laws.

However, increasing number of TCO wells increases the possibility of potential risks considering that Well Integrity Process (WIP) requires a lot of manual work and data review by engineers. In order to improve reliability of the process, the team has developed and successfully launched the Well Integrity Portal (WIP) dashboard to automate routine duties. As a result, fully deployed WIP has provided engineers with full set of interactive dashboard functionality, which includes, but not limited to: live data/metrics visualization, automated workflows for alert/notification, non-conformance report generation, etc. This paper will provide overview of TCO’s Well Integrity program and details on how Well Integrity Portal has been developed and deployed to ensure continuous benefit to the company and incident-free operation.
