Abstract

The following study is focused on the suggested strategy to attack a problem of Shallow Gas/Water flow are drilled and cemented without equipment to prevent blowouts in offshore fields. We analyze historical cases where abnormal pressure water sands observed in the resistivity log were not identified in the Pressure While Drilling tool. The event flow was observed by the remotely operated vehicle. We suggest a decision tree when a shallow gas/water flow unexpected. Such events cause an uncontrolled flow situation by placing at risk the safety of persons working in the maritime unit drilling, the same unit and economic losses for the execution of unplanned operations.
