Key points
- Places all released exploration wells (up to July 2024) within a technically consistent stratigraphic framework.
- Assigns both the PetroStrat K & T Sequences, and Ichron Sequences throughout every well within a regional multiclient, for the first time.
- Incorporates unreleased analytical biostrat data from 5 legacy PetroStrat multiclient studies, which this project supersedes.
A high-resolution, technically consistent and correlative, new chronostratigraphic, lithostratigraphic and sequence stratigraphic framework from first returns to TD, encompassing all 53 released Vøring Basin exploration wells. Vøring 2025 also provides evidence on the evolution of palaeoenvironments within each formation through time.
Integrates and supersedes 5 legacy multi-client (MC) studies, from which >1,900 unique PetroStrat IP-owned (i.e., not released) sample analyses are incorporated. Will unify disparate and taxonomically inconsistent, released biostratigraphic data. PetroStrat has extensive experience in this basin, having already studied 52 of these 53 wells.
With a focus on delineating sand prone depositional systems, this will help exploration teams to identify and consistently map sediment input, depositional setting and stratigraphy relating to development of the Nyk & Utgard Highs & Gjallar Ridge
Work Programme and Deliverables
- Application throughout each well of both of our interpretive stratigraphic schemes:
- Reservoir-scale PetroStrat K & T Sequences (compatible with our Lysing-Lange-2 MC).
- Regional Ichron Sequences (compatible with our Halten Terrace NSD, 213 wells).
- Sequence stratigraphy. Ichron and PetroStrat sequences will be applied, including sequence boundaries, maximum flooding surfaces and intervals where appropriate.
- Presents the results of our new (2023) integrated PetroStrat Composite Zonation Scheme for NW Europe, that rationalised PetroStrat & Ichron nomenclature, relative to GTS 2020.
- New stratigraphic mapping deliverables, to include:
- Sub-crop and supra-cropping lithostratigraphy & chronostratigraphy
- Sand member thickness
- Group component thickness
- Palaeoenvironmental interpretations to be derived from fully quantitative fossil assemblages in each well (where possible). Particularly important around Santonian-Campanian boundary & Maastrichtian.
- Our first new Norwegian multiclient study to be delivered through the Connect platform.
- This may precede a ‘Phase 2’ sedimentological study of reservoir quality controls and provenance.
