Fig. 26.12 The vintage 3D has been replaced by broadband 3D after the discoveries. The broadband 3D seismic gives a holistic
picture of the shallow and deep geology simultaneously
Logs read 40% shale in 100% sand
Gamma log from core no 1.
This is what it looks like

Fig. 26.13 Coring was a necessary trigger for the discoveries on the Utsira High. Indirect data types (wireline logs) need to be
calibrated. Without cores the Edvard Grieg discovery could have been overlooked
