To better understand the depositional environment in the Kvitvola prospect in the North Sea license PL 553, the license Operator arranged a field excursion to study analog outcrops of exposed sedimentary deposits in the Lusterian Basin in Portugal.

To better understand the depositional environment in the Kvitvola prospect in the North Sea license PL 553, the license Operator arranged a field excursion to study analog outcrops of exposed sedimentary deposits in the Lusterian Basin in Portugal.

License PL 553 is operated by Det norske with Bayerngas and Svenska Petroleum as partners. The Field Excursion was held by Andrew Taylor and Michael Ayress from Ichron. Thirteen employees from the three companies participated, providing an excellent opportunity for networking within the license.

The first part of this four day excursion was focused on fluvial deposits. The participants obtained practical experience in characterizing sediments from braided and meandering river systems. A braided river consists of a network of small channels separated by small and often temporary islands. In a meandering river, the water is moving in a curved shaped stream, eroding the outer banks and deposing sediments in the inner banks. The characteristics of the two depositional settings were discussed in terms of reservoir distribution and potential.

The second part of the excursion focused on shallow marine sediments. The participants visited a number of localities to study outcrops from the deeper slope up to the beach deposits. The group discussed the characteristics of the sediment packages and the impact of different depositional environments on reservoir distribution and potential.
