East Shetland Platform

With the long awaited UKCS 29th Frontier License Round upon us, discover the Palaeozoic to Eocene potential on the East Shetland Platform with 3D GeoStreamer® data.

15 000 sq. km of available 3D GeoStreamer data reveal multiple plays across the underexplored platform area, providing new insights into the geology and prospectivity of this key large frontier region. Proven and inferred targets include Palaeogene deltaic, shelfal and deep water sandstones, Triassic and Jurassic sandstones, Permo-Carboniferous carbonates and sandstones, fractured Devonian sandstones and fractured crystalline basement. The list is almost endless!

GeoStreamer is the Data You Need

Vast, unexploited sub-BCU potential has come to light, (see examples below). Palaeozoic-Jurassic reflectors are now visible on the GeoStreamer surveys and can be clearly mapped, highlighting large, as yet undrilled, fault blocks and anticlines. These resemble the simple large structural traps that characterize the existing Devonian fields, e.g. Cairngorm, Buchan & Clair, which typically contain a significant amount of recoverable reserves (some >1,000 MMboe).

Ten PGS surveys are available within the 29th Round Area of Interest, with more available in adjacent areas. Each was acquired within the last five years using GeoStreamer and imaged with PSTM or PSDM, providing the clearest images of the Palaeozoic section. More accurate sub-BCU imaging is now possible thanks to the surveys available in the area (see below).

Several deep-seated extensional structures are visible and have been annotated, including a prominent Devonian syn-rift wedge and partly inverted intra-platform Triassic basin (Crawford-Skipper Basin).
