Managed Pressure Drilling (MPD), which has its roots in Underbalanced Drilling (UBD) technology, has been growing steadily since its inception a decade ago. UBD, despite its long history, has remained a niche technology for some operators—will the same happen with MPD?
Managed Pressure Drilling offers some compelling advantages compared to conventional drilling, especially the ability to quickly map the downhole drilling pressure environment and rapidly respond to unknown pore pressures. In addition to maintaining constant bottomhole pressure, MPD allows drilling closer to pore pressure (‘walking the line’) which increases drilling rates and reduces non-productive time associated with higher overbalance pressures. In some cases, where the pore pressure/fracture gradient window is sufficiently narrow, drilling by any other means becomes impossible.
Despite these advantages there are still significant disadvantages with this technology, especially as this is still seen as a novel way of drilling to many people and requires different procedures and equipment. In addition, the perception that it involves extra cost, equipment and people (requiring justification from a cost/benefit perspective) and justifying the value of reduction of non-productive time (NPT) and any production enhancement is difficult.
The benefit of drilling with a ‘closed’ system is still not clear from a risk perspective and despite the fact that the safety record of this technology is good, many people consider drilling with, for example, a statically underbalanced drilling fluid, to be more risky than conventional drilling.
This forum will evaluate how participants, as industry leaders, should work together to change the MPD industry in the future. It is an opportunity to network, exchange ideas, and build consensus, bringing together like-minded professionals so that they can collaborate to shape the future.
