Global Infracambrian petroleum systems: a review

Abstract

This review covers global uppermost Neoproterozoic-Cambrian petroleum systems using published information and the results of studies undertaken by

From Neoproterozoic to Early Cenozoic: exploring the potential of older and deeper hydrocarbon plays across North Africa and the Middle East

“…The Neoproterozoic Eon, which extends from 1000 Ma to the base of the Cambrian at 542 Ma, is relatively poorly known from a petroleum perspective, despite the existence of potential, proven or producing plays in many parts of the world, including Oman, Mauritania, Siberia, China, India, Pakistan, Australia and both North and South America (Bhat et al 2009;Craig et al 2009;Ghori et al 2009). …”

“…One of the most critical issues determining the efficiency of older and/or deeply buried petroleum systems is, therefore, their burial history, and specifically the existence of a 'late' burial phase that can allow hydrocarbons to be generated, expelled, migrated and trapped in a suitably recent timeframe. Exceptions, such as the Neoproterozoic petroleum system of the Amadeus and Officer basins of Australia (Ghori et al 2009) or the Late Neoproterozoic -Early Cambrian petroleum systems of Oman (Blood 2001;Al-Siyabi 2005) and the Indian Sub-continent (Peters et al 1995) generally occur where evaporate super-seals are present (Schoenherr et al 2007) and/or where the post-trapping history is dominated by extreme tectonic stability.…”

International Field Workshop on the Marwar Supergroup, Rajasthan, India

“…The first field workshop on the Vindhyan Supergroup was organized during the year 2010 (Kumar and Sharma, 2012) and the next on the Marwar Supergroup was conducted during January 20-28, 2014 (Sharma et al, 2014). Besides the interest of academia, there is an increasing interest of the petroleum industry in the hydrocarbon potential of this region (Ghori et al, 2009;Craig et al, 2013)…”

Neoproterozoic–Cambrian petroleum system evolution of the Micang Shan uplift, northern Sichuan Basin, China: Insights from pyrobitumen rhenium–osmium geochronology and apatite fission-track analysis

“…Hydrocarbon (oil and gas) production and shows sourced from or reservoired in Proterozoic to Cambrian successions occur worldwide, and are an important economic resource (Bhat et al, 2012;Craig et al, 2009;Ghori et al, 2009). For example, the Lena-Tunguska Proterozoic-Early Cambrian (microfossils and K-Ar dates on glauconites show the oldest date is 590 -680 Ma) petroleum province, which includes the Lena Trough, the Kansk Basin, the Tunguska Basin, and the Sukhana Basin, located on the Siberian Craton, northern Russia, has a total estimated resource of 2 Bbbl (billion barrels) of oil and 83 Tcf (trillion cubic feet) of gas (Ghori et al, 2009;Meyerhoff, 1982). In addition, three potentially economically viable Proterozoic oil and gas systems have been found in Australia (McArthur, Urapungan and Centralian), which have a combined estimated resource of over 2 Bbbl of oil and 10 Tcf of gas (Bradshaw et al, 1994;Jackson et al, 1986;Munson, 2014).…”
