Fractures in rock happen on a subseismic scale, making it physically impossible to image them directly. That is just part of what Jesper Dramsch faces when doing his PhD at Danish Hydrocarbon Research and Technology Centre. But he knows his way around it.
Jesper Sören Dramsch holds a M.Sc. in Geophysics and B.Sc. Geophysics/Oceanography. Now he is a PhD student at Danish Hydrocarbon Research and Technology Centre (DHRTC) focusing on 4D seismic.
The project will focus on observing and quantifying the changes caused by fractures and faults. This will be done using a broad palette of methods.
“Changes in the amplitude of the seismic signal will be analysed to provide a better understanding of the changes caused by oil production. This will give valuable information about the flow patterns and along with a detailed fault interpretation help to quantify the effect of faults and thereby potentially also the permeability,” explains Jesper Sören Dramsch and continues:
“The seismic signal will be analysed for potential small changes which will be linked to the work done on fracture prediction. This will both help to validate the fracture prediction based on geomechanics and give valuable information about improved methods to link 4D seismic with the presence of fractures.”
