The mature fields on the NCS are moving towards tail end production and most new discoveries are complex and often marginal.
This year’s conference aims to present good multidisciplinary case studies and examples of novel and efficient ways of working on multidisciplinary reservoir characterization tasks. A main aim of the content will be to show how new digital technology can improve our reservoir understanding and predictions.
The conference committee is pleased to present this year’s core viewings:
Gullfaks Shetland/Lista
The cores from Gullfaks well 34/10-C-50 display the Early to Middle Paleocene Lista Formation and Late Cretaceous Shetland Group. The C-50 well was completed as a producer and therefore have both core data and dynamic data. The matrix permeability found in the chalk / marl succession of Shetland is found to be much less than the effective permeability identified from production tests. The Shetland reservoir is considered to be a fractured chalk reservoir.
Johan Sverdrup
The cores from Johan Sverdrup well 16/2-U-18 display the Mesozoic stratigraphy in the northern part of the field consisting of:
Upper Triassic, continental Hegre Group
Upper Triassic – Lower Jurassic, continental to paralic Statfjord Group
Middle Jurassic, shallow marine Vestland Group
Upper Jurassic – Lower Cretaceous, shallow- to open-marine Viking Group
Alta
Alta core display will focus on the Ørn Fm. and overlying Permo – Triassic clastic carbonate succession encountered in the eastern flank of the Alta structure. The main depositional environments / reservoir units will be illustrated.
