Petrophysical seismic inversion, aided by rock physics, aims at estimating reservoir
properties based on reflection events, but it is generally based on the Gassmann equation …

The geological factors of any reservoir, such as porosity, lithology, and fluid characteristics,
control the rock physics models. Several retrospective studies have discussed the methods …

For the successful discovery and development of tight sand gas reserves, it is necessary to
locate sand with certain features. These features must largely include a significant …

By treating contact stiffness as a variable, one can extend the effective medium
approximation used to obtain elastic stiffness of a random pack of spherical grains. More …

There are several productive petroleum fields in the North Western Desert (WD) of Egypt,
which received extensive investigations regarding their petroleum potential. However, a few …

The Bakken formation in the Williston Basin, is one of the largest tight oil reserves in the USA
and is currently the second largest oil producer in the nation. The Bakken formation is …

We have developed a recipe for using closed-form expressions of effective-medium models
to predict velocities in unconsolidated sandstones. The commonly used Hertz-Mindlin …

The sand intervals of the Lower Goru Formation of the Cretaceous age, widely distributed in
the Middle and Lower Indus Basin of Pakistan, are proven reservoirs. However, in the …

Carbonate reservoirs hold promising potential for hydrocarbon exploration, but they usually
exhibit complex pore structures, which lead to difficulties in the seismic/elastic prediction via …

Near‐surface seismic velocity structure plays a critical role in ground motion amplification
during large earthquakes. In particular, the local Vp/Vs ratio strongly influences the …
