I am a senior geophysicist dealing with surface seismic and borehole seismic, P and S waves, BEFORE, DURING and AFTER drilling.
Developing Geothermal ressources are even MORE challenging than oil and Gas.
I have worked for ARAMCO sometimes.
Faulting and permeable Fracturation remains tricky to establish without Drilling.
I would be pleased to offer help if I can, Through IFPEN.
Presently I am still refining the art of getting MORE information from the VSP data, for the geologists and for a better understanding of the subsurface structures: https://www.ifpenergiesnouvelles.fr/article/ifpen-aps-ppzg-orientation-3-component-rig-source-vsps https://www.ifpenergiesnouvelles.com/article/ifpen-aps-ppzg-orientation-3-component-rig-source-vsps https://www.researchgate.net/profile/Charles_Naville
