seismic method creates close-ups of chalk
using a combination of two seismic measuring methods, janina kammann, a geophysicist, creates new and detailed knowledge about what chalk strata look like. the new ?close- ups? mean that the oil
industry has more detailed information on the geology and geophysics in the oil-bearing strata. ?ere is much more to chalk than meets the eye. ?ere are big differenc- es in how porous or impermeable the oil-bearing chalks in the north sea are. for the oil industry, it is impor- tant to know the physical properties of the chalk strata at particular locations, because this has a bearing on how to recover the oil and gas, and whether it can be viable. so far, the seismic methods availa- ble for studying the chalk on land have resulted in images of the subsoil with a resolution of three to ten metres. now, the ambition of a new inter- disciplinary research project financed phd student janina kammann with the compact and portable surface vibrator source elvis iii machine in a chalk quarry near aalborg. photo: carsten albrechtsen 12 dhrtc 2016
