Abstract Accurate pore pressure models in wells are essential for ensuring the lowest cost and operational safety during exploration/development projects. This modeling requires integration of several sources information such as well data, formation tests, geophysical logs, mud weight, geological models, seismic geothermal sedimentation rate modeling. An empirical relationship between overpress...

Abstract The Moho – defined as the boundary that separates Earth’s crust from underlying upper mantle at depths of about 5 to 7 km beneath oceans and 30 40 below continents has been difficult pin down with observations. Different methods have yield a variety results, suggesting this simple definition may be misleading. Here, we present high-resolution deep penetrating seismic reflection data im...

The marine phosphorus cycle plays a critical role in regulating rates of primary productivity and thus the size biosphere. Yet, cumulative effects temperature change—and warming, particular—on burial remain poorly understood. Here, we explore benthic biogeochemical model that accounts for compounded effect on kinetics key diagenetic reaction pathways, diffusion coefficients, seawater p H, disso...

Active continental margins are the Earth's principal regions of active deformation and significant earthquake hazard. We apply the enhanced method called Scan Synthetic Aperture Radar (ScanSAR) interferometry to quantify active surface deformation in the coastal region of the South American active margin in central Chile between 22° S and 27° S. Here, as in other active margin settings, crustal...
