Summary:
Pore pressure profiles in Carbonate formations in the North Sea are subject to detailed study, however, there exists large uncertainty on the pressure transient in low porosity and low mobility Carbonates. In the past, the compaction and non-compaction based approaches have been used to resolve the pore pressure but high uncertainty over the results still remains, especially in the more tight zones due to a lack of trustworthy calibration data. In this paper the authors demonstrate that with the help of evolving formation testing technology, it is now possible to accurately measure formation pressures in extremely low mobility carbonates. It requires efficient collaboration between the operator and technology partner to come up with focused solutions which are wellbore centric. The example presented here specifically discusses a North Sea field challenge.
