Paleochannel sands as conduits for hydrocarbon leakage across faults: An example from the Wilmington oil field, California E&P Note
Leakage in a faulted anticline
Depositional sequences, original oil-water contacts, and compartmentalization by faults were investigated in the Tar zone, a lower Pliocene turbidite deposit. A paleochannel within this deposit was found to leak through several faults, causing reduction and depletion of hydrocarbons.
Gas geochemistry of the Mobile Bay Jurassic Norphlet Formation: Thermal controls and implications for reservoir connectivity
Resource exploitation in the Mobile Bay gas field, offshore Alabama, is challenged by reservoir quality, presence of H2S, and preservation of hydrocarbons. This paper addresses the complex thermal and redox processes as they affect gas composition and reservoir connectivity.
Reconstructing morphological and depositional characteristics in subsurface sedimentary systems: An example from the Maastrichtian-Danian Ormen Lange system, Møre Basin, Norwegian Sea
A submodern depositional environment is investigated in order to predict morphological characteristics and sediment transport in ancient source-to-sink systems where data are missing or where more detailed insight into the morphology and the sediment transportation systems is desired.
Sandstone-Body Dimensions in a Lower Coastal-Plain Depositional Setting: Lower Williams Fork Formation, Coal Canyon, Piceance Basin, Colorado, U.S.A.
Within the Williams Fork Formation, discontinuous fluvial deposits form the main reservoirs, and their stratigraphic distribution and low continuity make them difficult to correlate and map. This study addresses the field-scale architecture and dimensions of these sandstone deposits.
