Europe

Chemostrat has over 20 years’ experience in the North Sea and adjacent areas. As interest in shale gas exploration in Europe increases, there has been a corresponding increase in the application of our services to onshore Europe prospects. Below is a summary of our experience. Please contact us for more specific details.

Southern North Sea

Permian

Refined correlation of the Silverpit / Leman.
Characterisation of the Leman sands from the V fields, Cutter and onshore Netherlands, and Zechstein sequences, offshore Netherlands.
32 wells analysed as part of our SNS provenance study on the Permian, Dutch wells from E, F, J, K & L and UK wells from quads 44 & 49. Available for purchase

Carboniferous

100+ wells in blocks 44 and 49 covering the Stephanian, Westphalian and Namurian. (see Carboniferous examples). Leading to a new Westphalian correlation scheme for the SNS.
>60 wells analysed as part of 3 non-exclusive data sets, wells from the Upper Carboniferous UK quads 44 & 39 and Dutch wells from D, E, F, K, G, H & J. Available for purchase
Provenance, marine band and coal correlation studies.
Identification of the Basal Permian Unconformity (BPU) and correlation of the Boulton, Ketch, Cleaver, Westoe and Caister formations.
Namurian characterisation and correlation in onshore wells, Saltfeetby.

Wellsite deployments for Leman, Ketch, Cleaver and Cretaceous Chalk geosteering.

Central North Sea

Cretaceous : Chalk (Tor and Ekofisk) correlation in offshore Netherlands and Ekofisk Field.
Middle and Upper Jurassic : 100+ wells integrated chemostratigraphy and sedimentology on the Middle and Upper Jurassic successions, providing an independent correlation framework for the UK CNS. Available for Purchase
Triassic : 60+ wells in the Jade, Judy, Joanne and Jasmine fields.
Triassic : Integrated chemostratigraphy and reservoir geology revision of both the UK and Norwegian Central Graben region, providing an enhanced intra-Triassic correlation and reservoir model for the area. Available for Purchase.
Triassic : Wellsite deployment for geosteering.

Northern North Sea

Cretaceous : Lower Cretaceous turbidites of the Britannia area.
Jurassic : Otter, Brent and Ninian fields.
Triassic / Lower Jurassic : refined correlation (c. 60 well correlation), in particular for Teist, Lomvi, Lunde, Statfjord and Dunlin, on both field and sub-regional scales. UK Quads 3, 210 and 211. Norway Quads 30, 33 and 34.
Devonian : Buchan field. Correlation of high density turbidite sequences and sediment dispersal mapping. C.10 well correlation.

West of Shetland

Devonian : Clair field, c. 10+ well correlation.
Tertiary : Rosebank area, successful characterisation of basalt horizons, to improve correlation of the interbedded clastic reservoir and aid real-time drill bit positioning.
Tertiary : >20 well turbidite sequence correlation and sediment mapping.
Lower Palaeocene : 22 well integrated chemostratigraphy, heavy mineral, zircon geochronology and petrography study on the T10-T38 sequences. Investigating the sediment dispersal patterns in the Flett bub-basin.
