This uncertainty can be significantly reduced through the integration of geological scenario, compartmentalisation and sub-seismic fault prediction, seismic QI (quantitative...

... not allow for the filling up of a depleted reservoir, and a new discovery therefore had to be used. The most suitable undepleted field, the Grijpskerk field, had a number of very significant uncertainties, including: Complex overburden; evidence of compartmentalisation; diagenetic impairment; and the need...
