A total of 195 cuttings samples were collected from between 229 - 2226 m from the Natsek E-56 well of Beaufort-Mackenzie Basin for Rock-Eval Pyrolysis. The Natsek E-56 well is being investigated as part of a multi-disciplinary study of petroleum systems in the Beaufort-Mackenzie Basin, carried out by the Geological Survey of Canada (Calgary) under the Geo-Mapping for Energy and Minerals (GEM) Program, Western Arctic Project. Organic matter characterization in conjunction with other on-going analyses of rock preserved in Natsek E-56 cuttings will be used to interpret the paleoenvironment, paleotemperature and paleosalinity during the Early to Middle Eocene to inform hydrocarbon source rock characterization, with broader implications extended to understanding Arctic Ocean paleoceanography and paleoclimate. Rock-Eval pyrolysis parameters suggest that the samples from the Taglu and Aklak sequences, preserved in Natsek E-56, contain a mixture of poor to fair petroleum source rocks with immature to early mature Type III/IV kerogen. The Tmax values however, indicate that the cuttings from Natsek E-56 remain outside the window for petroleum generation. Below about 2030 m there is a dramatic increase in the TOC content of several samples, suggesting that the Aklak sequence, a sandstone dominated succession, contains carbonaceous mudstone or coaly mudstone beds.
