DOI: 10.1016/j.petrol.2020.107237
Abstract: Abstract As for a typical machine-learning method, large volume of labeled examples is required to train and update neural parameters that are later used on new datasets. Well logs usually provide true values of elastic… read more here.

DOI: 10.1016/j.petrol.2020.107416
Abstract: Abstract Unconventional hydrocarbon reservoirs, such as shale rocks, are generally transversely isotropic with a vertical axis of symmetry (VTI). The identification of sweet spots in these reservoirs, which must take into account this anisotropic character,… read more here.

DOI: 10.1111/1365-2478.12637
Abstract: ABSTRACT The sequestration of CO2 in subsurface reservoirs constitutes an immediate counter‐measure to reduce anthropogenic emissions of CO2, now recognized by international scientific panels to be the single most critical factor driving the observed global… read more here.
