Bb. Stump et Pb. Flemings, Overpressure and fluid flow in dipping structures of the offshore Gulf of Mexico (EI 330 field), J GEOCHEM E, 69, 2000, pp. 23-28
Estimated pressures in overpressured Plio-Pleistocene muds of the Eugene Is
land 330 (E.I. 330) field (offshore Louisiana) differ from pressure measure
ments in adjacent sands in a consistent manner. At structural highs, fluid
pressure in sand exceeds pressure in the adjacent mud; at structural lows,
the relationship is reversed. Two physical models describe the origin of th
ese pressure differences: rapid loading and steady-flow. Observation and th
eory suggest that stratigraphic layering focuses fluid flow toward structur
al highs. (C) 2000 Elsevier Science B.V. All rights reserved.
