“…As there are no direct data concerning the physical and chemical properties of postulated hydrocarbons in the subsurface of the NE Greenland shelf, the assessment relied on statistical ranges derived from the USGS Analogue Database (Charpentier et al 2008), and on compositional data from specific analogues of known oil and gas accumulations in the Norwegian Sea and the Barents Platform.…”

“…The number of undiscovered accumulations in the South Danmarkshavn Basin AU was estimated from the range of field densities in 32 rift/sag basins from the analogue database of Charpentier et al (2008) as applied to the area of the AU. The maximum field density in this analogue set is in the Viking Graben of the North Sea.…”

Geological features of NE Greenland suggest large petroleum potential, as well as high uncertainty and risk. The area was the prototype for development of methodology used in the US Geological Survey (USGS) Circum-Arctic Resource Appraisal (CARA), and was the first area evaluated. In collaboration with the Geological Survey of Denmark and Greenland (GEUS), eight 'assessment units' (AU) were defined, six of which were probabilistically assessed. The most prospective areas are offshore in the Danmarkshavn Basin. This study supersedes a previous USGS assessment, from which it differs in several important respects: oil estimates are reduced and natural gas estimates are increased to reflect revised understanding of offshore geology. Despite the reduced estimates, the CARA indicates that NE Greenland may be an important future petroleum province.

“…For basins with discovery histories, data from known accumulations (IHS Energy 2007) were allocated to AUs, then spreadsheets were tabulated and exploration history plots were prepared. On the basis of the geological analysis and burial history modelling, the geologists selected sets of analogues from an analogue database constructed from 246 geologically classified AUs assessed in the 2000 World Petroleum Assessment (Charpentier et al 2008). Many of the variables required for the numerical assessment were represented in the analogue database, including numbers of accumulations per unit area (field density), median and maximum accumulation sizes, and ratios of numbers of oil to gas accumulations.…”

The USGS has assessed undiscovered petroleum resources in the Arctic through geological mapping, basin analysis and quantitative assessment. The new map compilation provided the base from which geologists subdivided the Arctic for burial history modelling and quantitative assessment. The CARA was a probabilistic, geologically based study that used existing USGS methodology, modified somewhat for the circumstances of the Arctic. The assessment relied heavily on analogue modelling, with numerical input as lognormal distributions of sizes and numbers of undiscovered accumulations. Probabilistic results for individual assessment units were statistically aggregated taking geological dependencies into account. Fourteen papers in this Geological Society volume present summaries of various aspects of the CARA.

“…For the assessment of the Khatanga Saddle, Lena -Anabar Basin and Northern Priverkhoyansk Foredeep AUs, two analogue datasets (Table 1) were chosen from the USGS Analogue Database (Charpentier et al 2007): (1) foreland basins (24 analogues) and (2) rifted passive margins and foreland basins with mixed clastic and carbonate depositional systems (15 analogues). The analogues were used to estimate the numbers and sizes of undiscovered fields (Fig.…”

Assessment of undiscovered petroleum resources of the north and east margins of the Siberian craton north of the Arctic Circle

The Siberian craton consists of crystalline rocks and superimposed Precambrian sedimentary rocks deposited in rift basins. Palaeozoic rocks, mainly carbonates, were deposited along the margins of the craton to form an outwardly younger concentric pattern that underlies an outward-thickening Mesozoic sedimentary section. The north and east margins of the Siberian craton subsequently became foreland basins created by compressional deformation during collision with other tectonic plates. The Tunguska Basin developed as a Palaeozoic rift/sag basin over Proterozoic rifts.The geological provinces along the north and east margins of the Siberian craton are immature with respect to exploration, so exploration-history analysis alone cannot be used for assessing undiscovered petroleum resources. Therefore, other areas from around the world having greater petroleum exploration maturity and similar geological characteristics, and which have been previously assessed, were used as analogues to aid in this assessment. The analogues included those of foreland basins and rift/sag basins that were later subjected to compression. The US Geological Survey estimated the mean undiscovered, technically recoverable conventional petroleum resources to be c. 28 billion barrels of oil equivalent, including c. 8 billion barrels of crude oil, 103 trillion cubic feet of natural gas, and 3 billion barrels of natural gas liquids.
