Azinor, UKCS: Hunting 500 MMboe

Azinor, UKCS: Hunting 500 MMboe

Azinor Catalyst Limited has committed to the Oil and Gas Authority its intent to drill two wells in 2020 as part of a three-well drilling campaign.

The three prospects; Boaz, Hinson and Goose have been defined and de-risked utilizing new generation broadband seismic data and leading-edge quantitative geoscience techniques, as stated by Henry Morris, Technical Director.

The three independent prospects are estimated to contain combined gross Pmean prospective resources of 495 million barrels of oil equivalent.

Boaz prospect

Boaz is located within the South Viking Graben and immediately adjacent to the UK/Norwegian median line and the Eirin Field, which is currently being developed by Equinor as part of the wider Gina Krog Field development.

The primary target is the Triassic Skagerrak Fm, comprising thick and well-developed fluvial braid plain deposits, proven by numerous well penetrations in adjacent Norwegian acreage to the east.

Gross recoverable resources are estimated at 242 MMboe (Pmean), with an upside of 544 MMboe (P10).

Hinson prospect

Located within the axis of the West Central Graben of the UK Central North Sea.

The main play focus on block 21/25c is on the Upper Jurassic deep-water turbidite and shallow marine shoreface systems. Reservoir sands sit within or immediately proximal to oil mature, organic-rich Kimmeridge Clay Fm source rocks.

Azinor’s work program involving seismic data reprocessing and conditioning along with other geotechnical studies has significantly de-risked and strengthened the definition of the Hinson prospect. The conditioned seismic data is now of such a quality where on lap and down lap of reflectors can be mapped with confidence to help delineate fan geometries indicative of sands. This combined with petrophysical and subregional biostratigraphic studies has de-risked the age and proven a strong geological model for the deposition of these untested J62 mass flow sands.

Gross recoverable resources are estimated at 178 MMboe (Pmean), with an upside of 329 MMboe (P10).

Goose prospect

The Late Hauterivian-Early Barremian aged K34 Scapa sands form the primary reservoir at Goose although geophysical lithology indicators highlight additional upside within older Early Hauterivian K20 Scapa units. These shallow marine turbidites derive from the eroded crests of the surrounding Devonian highs and Caithness ridge as well as reworked clastics deposited on the Halibut Shelf. Additional Scapa reservoir targets have been identified at Long Bird, which together with Goose form direct analogues to the Lower Cretaceous reservoirs at North Claymore.

Gross recoverable resources are estimated at 71 MMboe (Pmean).
