Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1062
... Basin. We explore the value-addition brought by elemental spectroscopy and advanced sonic scanning in evaluating the hydrocarbon potential of basement rocks. Geomechanical compliance analysis reveals critically stressed structural features in the weathered intervals, providing additional consistency...

Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1690
... ABSTRACT: The majority of notable induced earthquakes happen on faults within the basement overlain by sedimentary layers. Pore pressure elevation and poroelastic effects have been considered as the driving mechanisms. In this article, a 3D numerical simulation is utilized to investigate...

Paper Number: ARMA-2021-1948
... the incremental frictional energy and observed earthquakes with the magnitude larger than 1.5. The calibrated simulation results suggested that the poroelastic effect was the driving mechanism of the earthquakes in the basement. The ACE algorithm found the maximum correlation between the energy and the earthquake...

... to estimate the slip potential with relation to changes in the relative magnitudes of the three principal stresses by using a discrete A ϕ parameter. We present an updated FSP map of the Delaware basin utilizing the continuous stress orientation map and newly identified basement-rooted faults in the basin...

... seismic effects: in the deep geothermal well GPK-1 drilled in Soultz, eastern France, FHC operated an S-wave VSP campaign in 1993. No significant S-wave splitting effect could be evidenced due to unexpected velocity heterogeneities within the granitic basement rock mass. In the Aigion-10 well drilled...

... length's distributions, correlation coefficients, power law coefficients, and fractal dimensions. The second approach is the analysis of the fractures affecting the basement and the different Cambro-Ordovician units, by using the same input data and determining the same parameters and outputs. The 3D...

Paper Number: ARMA-2019-0375
... ABSTRACT: The fractal dimension is applied to verify whether the 2-D fracture networks that affect the basement and the Cambro-Ordovician reservoirs analog in north Hoggar shield have fractal dimension. The Ajjers, In-Tahouite, and Tamadjert units compose the Cambro-Ordovician reservoirs...

Paper Number: ARMA-2019-0491
... ABSTRACT: From 2009 to 2016, a drastic increase in seismic activity occurred in the Central and Eastern US (CEUS), and particularly in the Oklahoma-Kansas region. The majority of hypocenters have been traced to the crystalline basement rock. Forecasting future seismic hazard and predicting...

Paper Number: ARMA-2015-384
... faults may especially induce large seismic events, often below the reservoir in the crystalline basement. Understanding the mechanisms of seismic events induced under these circumstances is the key for hazard predictions and mitigation measures. In this study we model a simplified pressure diffusion...
