The critical zone (CZ) comprises the near-surface region of the Earth where biological, physical and chemical weathering processes form porous soil and weathered bedrock from initially fresh bedrock. The structure of the ...

By projecting observed microseismic data backward in time to when fracturing occurred, it is possible to locate the fracture events in space, assuming a correct velocity model. In order to achieve this task in near real-time, ...

This study focuses on investigating the effect of the electronic spin transition of iron on the elasticity of the candidate lower mantle ferropericlase (Mg,Fe)O. This may be relevant to our understanding of the seismic ...

Relating well log data to seismic data is an important step in integrated reservoir characterization studies. Traditionally, an interpreter uses well log data, which has high vertical resolution but little lateral coverage, ...

Successful exploration for hydrocarbon reservoirs requires understanding seismic response for different sandstone lithologies. Today, many new targets lie within shale-rich environments such as mud-rich deltaic systems, ...

Organic rich Murdock reservoirs require hydraulic stimulation to be economically productive. Zones of high fracture density are desired due to the increase in permeability they would have. Thus, fracture characterization ...

Geophysicists often relegate shale reservoirs as having higher symmetries (e.g., transversely isotropic (TI) or isotropic) than what reality demonstrates. Routine application of TI (or even isotropic) algorithms to ...

Seismic waves can either be reflected or diffracted by subsurface objects depending on the object's geometry. Diffactions can be used to determine details about the small-scale features that generate them, such as karsts, ...

Scientific understanding of the mechanics of continental breakup in the absence of voluminous magmatism has dramatically evolved over the past decades. Numerical and conceptual rift models have elucidated the temporal and ...

The Morichito Subbasin is a southwest-northeast oriented depocenter that is located in the Eastern Venezuelan Foreland Basin (EVFB). The Morichito Subbasin covers an approximate area of 1,000 km² between the Serranía del ...
