INTRODUCTION
In the terminology of the U.S. Geological Survey (USGS) World Energy Project, the eastern Barents Sea region of Russia contains two large Mesozoic basin provinces, South Barents and North Barents, separated by the Ludlov Saddle (fig. 1). The major petroleum system for this area has widespread, mature Triassic gas-prone shale source rocks with most identified reserves within Jurassic siliciclastic reservoir rocks. It is herein called the South and North Barents Triassic-Jurassic total petroleum system (#105001). There also are largely immature, oil-prone Jurassic shale source rocks (Bazhenov-Hekkingen stratigraphic equivalent of adjacent regions) associated with potential Jurassic and Cretaceous sandstone reservoirs. Paleozoic shaly carbonate source rocks (Devonian Domanik stratigraphic equivalent from the Timan-Pechora Basin), if present in the eastern area, might contribute gas and liquids to various reservoir rocks. 

References listed in this report include a selection of those most recent and most pertinent to the subject matter. Not all are specifically cited in the text. Translations from original Russian papers are reported with the translated publication date. For one paper, Gramberg and others (1998), the translation date is ten years more recent than the original publication date. The Norwegian Petroleum Society (NPF) Special Publication No. 2 is referenced as 1993, although there are contradicting publication dates of 1992 (first page of all individual articles) and 1993 (title page) in the book. No stratigraphic column is presented for the region because only age nomenclature is used in the literature for most of the region.
