High-resolution 3D seismic imaging and refined velocity model building improve the image of a deep geothermal reservoir in the Upper Rhine Graben
Over the past 35 years, geothermal projects have been developed in the Upper Rhine Graben (URG) to exploit deep geothermal energy. Underneath approximately 2 km of sedimentary deposits, the deep target consists of a granitic basement, which is highly fractured and hydrothermally altered. Therefore ...
Accurate Depth Imaging With Advanced Velocity Modeling
The complex Central North Sea overburden, featuring shallow channels, contourites and injectites, presents a challenge for velocity modeling and often leads to distortions and difficulties in accurate depth placement of deeper targets.
De-risking Complex Traps With Salt Modeling and Dual-azimuth Imaging
Complex salt tectonics presents a key geological challenge in the Central North Sea. Salt flank and subsalt imaging has historically been a problem when evaluating complex stratigraphic traps.
Revealing Mesozoic Potential With Improved Deep Imaging
A key challenge to unlocking the potential of Jurassic and Triassic reservoirs in the Central North Sea is the presence of artefacts and noise in seismic images. The presence of random noise, water-bottom and inter-bed multiples prevents accurate sub-BCU mapping and differentiation of the ...
Solving Shallow Complexities With Absorption Anomaly Modeling
The complex overburden in the Central North Sea region includes features such as shallow gas accumulations, contourites and channels. These represent potential drilling hazards and result in velocity and absorption (Q) anomalies that degrade the deeper image.
