Assessing Thermal Maturity of the Pendência Formation (Potiguar Basin) Using Vitrinite Reflectance and Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Palynofacies assemblages from the onshore Potiguar Basin display a wide thermal maturity range, with vitrinite reflectance (%Ro) values of 0.46–2.72 measured from nine samples at depths of 1059–4443 m. A strong correlation exists between %Ro and Raman parameters, specifically the G‐band's full width at half maximum.

ANN‐Based Green's Function Approach for Reservoir Geomechanics

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Green's functions have been a tool to analyze important reservoir geomechanics effects like subsidence, compaction, well closure, and permeability variation. However, the classical Green's function is related to linear elastic, homogenous, and geometrically simplified media.

Multi‐scale geophysical imaging of neotectonic fault activity in the northern Upper Rhine Graben, Germany

open access: yesNear Surface Geophysics, EarlyView.
Abstract A comprehensive multi‐method geophysical strategy is used to investigate two faults in the Northern Upper Rhine Graben. Combining industrial 3D seismic data with our own 2D P‐ and S‐wave seismic, electrical resistivity tomography (ERT) and ground‐penetrating radar (GPR), we created comprehensive subsurface images of the faults. 3D seismic data
