Title: Convection in the oceanic crust: Simulation of observations from deep sea drilling project hole 504B, Costa Rica Rift

Abstract

Three-dimensional modeling of convection in the oceanic crust at Deep Sea Drilling Project site 504B using an integral finite difference model reasonably duplicates underpressures, surface heat flow, downhole temperature profiles, and fluid drawdown rates observed by in situ measurements in the borehole. The major constraint to produce such good fits is the permeability versus depth functions, a quantity which was actually measured in the borehole.
