Seismic reflection imaging is a geophysical method that provides greater resolution at depth than other methods and is, therefore, the of choice for hydrocarbon-reservoir exploration. However, seismic has only sparingly been used to explore monitor geothermal reservoirs. Yet, detailed images reservoirs are an essential prerequisite assess feasibility projects reduce risk associated with expensive drilling programs. The vast experience hydrocarbon much offer in illuminating route toward...
Deep neural networks (DNNs) have the potential to streamline integration of seismic data for reservoir characterization by providing estimates rock properties that are directly interpretable geologists and engineers instead elastic attributes like most standard inversion methods. However, they yet be applied widely in energy industry because training DNNs requires a large amount labeled is rarely available. Training set augmentation, routinely used other scientific fields such as image...
Abstract In NW Europe, the late Carboniferous Variscan collision between Laurussia and Armorica‐Gondwana continental blocks led to development of a crustal‐scale north‐verging thrust system along southern Laurussian margin. northern France, 3‐D geometry kinematics deformation front have been investigated on basis reprocessing interpreting 532 km industry‐level seismic reflection profiles. This extensive imaging provides new constraints structural kinematic features orogenic front. It...
Abstract Stephanian to Permian post-orogenic basins (SPB) outcrop in several limited locations and around the present-day French Variscan basement. Little is known about their subsurface occurrences beneath post-depositional sedimentary cover. Our work intends decipher structural evolution of hidden SPB southwestern Paris basin, where only a few regional studies have aimed determine location Mesozoic approach based on reprocessing interpretation 36 seismic lines (1480 km) acquired by oil...
Abstract A new structural model is presented for the Permo‐Carboniferous Lorraine Basin (NE France), a major intramountain basin that developed during latest stages of Variscan orogeny (ca. 315–270 Ma). Digitalized well logs and reprocessed seismic data were used to decipher kinematic evolution this located along Rhenohercynian orogenic suture zone. The was initiated late collision stage (Early Middle Pennsylvanian) in wedge‐top position upon Saxothuringian retro‐wedge. syn‐orogenic sequence...

In order increase reliability estimated...

To reduce risks related operations, reliable digital models needed: they make it possible predict depth aquifers away from borehole locations, and thermal hydrological evolution by supporting detailed water heat flow simulations. This paper presents a 3D geomodel developed for this purpose southern Paris Basin France Orléans area....
We present a new strategy for depth velocity model building from pre‐stack time migrated gathers. It is based on dense volumetric dip and residual move‐out (RMO) picking in the prestack domain. The kinematic information demigrated to compute multi‐offset un‐migrated attributes — called seismic invariants used as input data tomography. Compared corresponding existing domain, our allows fully take advantage of previous imaging project. bypasses initial migration required RMO depth. Furthermore...

A new structural model is presented for the Permo-Carboniferous Lorraine Basin (NE France), a major intramountain basin that developed during latest stages of Variscan orogeny (ca 315–270 Ma). This buried in NE France below Paris but outcrops southern Germany (Saar-Nahe Basin). Digitalized well logs and reprocessed seismic data were used to decipher kinematic evolution this located along Rhenohercynian orogenic suture zone. The initiated late collision stage (Late...
A wide range of geophysical methods is used for the exploration deep geothermal resources. It aimsat characterizing fractured network and its capacity fluid/heat extraction. This relieshowever on techniques to 1) image geometry networkbut also 2) characterize petro-physical properties fracture matrix. The challengeis however that inverse problem ill-posed multi-scale.To overcome these challenges, we propose here take a multi-physics multi-scale approach thegeophysical/petro-physical problem....
