Fluid Flow Simulation for Predicting Bottomhole Pressure That Considers Wellbore Storage Effects Under Shut-In Conditions in Deepwater Drilling

Journal of Marine Science and Engineering
Under shut-in conditions in deepwater drilling, the gas invading the bottomhole ascends along the wellbore and accumulates at the wellhead, forming a high-pressure trap, challenging wellbore pressure prediction and control.

Seismic Stratigraphy of Eocene–Recent Mixed Depositional Systems on the SE New Zealand Continental Margin, Great South Basin

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.
