PGK-lezing: de ontdekking van L11-Gillian

De maandelijkse lezing van de Petroleum-Geologische Kring staat op 19 april in het teken van de ontdekking van het offshore gasveld L11-Gillian, in het najaar van 2015. De productie begon een jaar later, in oktober 2016. Rutger Gras (ONE) en Richard Neale (Cegal) vertellen over het veld, met de nadruk op de fault seal. Op Earth Doc is een samenvatting te lezen van hun bevindingen (Engelstalig, zie hieronder).

Programma:
17.00 – 18.00 borrel
18.00 – 19.00 lezing

English version (summary from Earth Doc website):
In 2015 Oranje-Nassau Energie (ONE), operator of the Gillian Unit joint venture, drilled the L11-14 exploration well targetting the Gillian prospect. This well found the Permian-aged Rotliegend reservoir sands (the Upper Slochteren) gas bearing with virgin pressure. The Gillian gas field is a downthrown fault-closed tilted fault block, vertically sealed by Zechstein evaporites, in a location adjacent to the depleted L11b-A gas field. Pre-drill the critical risk for the Gillian prospect was the fault seal required to effectively trap gas in the Upper Slochteren sands. This case study demonstrates how a Rotliegend downthrown fault closure was derisked by a combination of conventional seismic interpretation complemented by seismic reservoir characterisation and structural modelling.
Rutger Gras (ONE) and Richard Neale (Cegal) will tell in the monthly PGK lecture on Wednesday, April the
