CASE STUDY Using all available data plays a vital role in successful drilling operations
Challenge: Offshore operations can be very complex and time consuming. Often the actual drilling of strata only occupies a fraction of the whole well. Complications due to improper pore pressure and/or fracture pressure estimation and management can lead to rapidly increasing costs as non-productive time accumulates. Not only during the drilling process, but for the entire time the hole is open to the surface, when a continuous stream of information is being provided about the pore pressures and fracture strength of the exposed wellbore.
Solution: Combine both time- and depth-based data to fully understanding the pore pressure regime and mitigate any non-productive time without the need to wait for external information sources.
Results: A proactive real-time pore pressure estimation provides significant benefits and is increasingly becoming an integral part of drilling operations by saving extensive non-productive time, alert the rig personnel of impending underbalance drilling and aiding the drilling team in determining the deepest that a hole section drilled without exiting the drilling window.
