Geomodelling for CCS, a bridge too far?
Traditionally, geomodels are built in a simplistic fashion, taking into account the inherent degree of uncertainty in the input data. Attempting to accurately depict an unseen geological object, often multiple…
“We should have looked at that regional seismic line with more care before signing off on a plan for drilling”
We, geologists, have the primacy of observation of rocks dinned into us during our earliest work in the field, with that message then reinforced by later events in our lives.…
