Environmental & Engineering Geoscience (2022) 28 (4): 361–369.
... electrode arrays (i.e., pole-dipole and Wenner-Schlumberger [WS]) with electrode spacing of 6 m up to 570 m in length. The resistivity data were digitally processed through RES2DINV software. The formation of fractured rock in the overburden caused by underground mining operations was clearly distinguished...

Seismological Research Letters (2022) 93 (3): 1930–1942.
...) V S ( σ v ′ ) = V S , surf ( σ v ′ + p a p a ) n / 2 , in which V S ( σ v ′ ) is the shear‐wave velocity at a depth with overburden effective stress σ v ′ (kPa); V S , surf is the shear‐wave velocity near...

Interpretation (2022) 10 (1): SA15–SA24.
..., statistical comparison of well log and seismic-derived impedances enables us to obtain a shale impedance model for a lithology baseline to detrend the impedance from the effects of burial and overburden. This has the effect of unmasking anomalies associated with hydrocarbon-bearing sands and serves...

... perform a feasibility study to understand the influence of the overburden and reservoir properties, and processing and inversion steps, which together determine the success of the fracture interpretation from seismic data. The 1D model properties (orthorhombic for overburden and reservoir) are first...

...Katie M. Smye; Peter H. Hennings; Elizabeth A. Horne ABSTRACT Constraining the magnitude of vertical stress ( S v ), or overburden pressure, is key in determining a region’s stress state and has implications for reservoir geomechanics and the potential for induced seismicity. Of the principal...

... ( FDIST ), and the erosion thickness (Δ H ). Finally, the vertical effective stress and overpressure were predicted using the predicted Δ VES , overburden stress, and loading curve. We found that mudstones formed at different rates of deposition would have different loading curves, which is a piecewise...

...Martin Landrø; Bjarte Foseide; Izzie Yi Liu ABSTRACT We have used simple time-shift analysis of diving waves to analyze shallow gas layers in a sedimentary overburden. By using simple equations for how the traveltime will change if a thin sand layer is charged by gas in a localized and constrained...
