North Sea Sele Sands Study High Resolution Stratigraphy of the Eocoene and Paleocene Selected Well Map

PetroStrat is pleased to announce this regional 50+ well non-proprietary biostratigraphic study. This study brings with it a better understanding of the Eocene and Paleocene aged sands in the southern part of Quad 22 and northern parts of Quads 28, 29 and 30. The principal study objective seeks to help differentiate the numerous aged sands within both the Sele and Lista Formations to facilitate improved seismic mapping and reservoir characterisation. Since the discovery of the

Since the discovery of the Catcher Field in 2010 (followed later by the Varadero, Burgman, Carnaby and Bonneville satellite discoveries) there has been renewed interest in the prospectivity of Eocene-aged sands within the northern part of Quads 28 and 29. More recently, the Vorlich/Marconi discovery in block 30/1f has helped extend this interest further to the east and has created further discussion as to the precise age and origins of some of these locally developed/ channelised high net/gross sands across the region.

A Key Reservoir – The Forties Sanstone Member

The Forties Sandstone Member provides an important reservoir across some of the Gannet fields and to the south and east (e.g. at Starling and Fram). It is also a significant reservoir in the south eastern portion of Quad 22 and in to Quad 23 where the Lomond, Columbus, Scoter and Pierce Fields are situated, albeit that the sands at these localities are largely sourced from the main Forties fan extended down the Eastern trough of the Central Graben from a more north westerly directly. This study will seek to break out all 11 of the PetroStrat F-units within the Forties (Units S1b – S1a).

Sands within the Late Paleocene aged Lista Formation are also prospective across the study area. They are being exploited at Stella (block 30/6) and across J Block (30/7). However, accurately dating these sands has proven challenging across much of the area, especially in the east, due to the prevalence of reworking from the Maureen Formation (and Chalk) both above and below the sands.

Study Deliverables

North Sea Sele Sands Study High Resolution Stratigraphy of the Eocoene and Paleocene PetroStrat Palynological Zonation
  • The study will provide a biostratigraphic database for 50+ wells with a focus on the interval from within the Balder Formation to the upper part of the Maureen Formation. The fossil data will be interpreted, zones applied and lithostratigraphic and sequencestratigraphic picks incorporated in to the stratigraphic summary charts. A set of regional correlations will be included in the report.
  • The study will include over 1200 new palynological analyses and over 500 new micropalaeontological analyses with sampling targeted to help resolve stratigraphic ambiguities.
  • All data will be available digitally as .csv files, StrataBugs dex files, tops tables and as an ODMTMproject inclusive of correlations.
  • Interim data sets will be provided to companies that pre-commit to the study at regular intervals, commencing with a data package incorporating all the wells already worked (the study was initiated in Q3 2015).
  • PetroStrat is willing to add in additional wells that interested parties may wish to see included in the study. Please contact us to discuss this or to arrange a presentation.
