Development of a data integrate tool for cement plug and abandonment

With an increasing number of mature offshore/deep-water wells and progressively more strict regulatory requirements, plug and abandonment (P&A) is becoming a more complex issue and expensive, time-consuming initiative. It is necessary to understand the current status of well assessing the qualit...
