Baltic-Paleozoic: New Regional Kinetics Package
July 21, 2015
This data package with key Lower Paleozoic Baltic Basin samples is based on 28 Cambrian, Ordovician and Silurian samples of variable maturity from Lithuania. Rock-Eval and pyrolysis gas chromatography data are provided for the whole sample set. Late Gas Potential was determined on eight of these samples. Full PhaseKinetics analysis on two selected... More
Norwegian Viking Graben regional source rock kinetics study released
May 4, 2015
This new PhaseFinder source rock kinetics Package addresses Draupne Formation source rock heterogeneity northwest and southwest of the Stord Basin. Major discoveries prove these areas as key exploration targets. Bulk and compositional kinetic data of 10 key immature source rocks assist in predicting the relative volumes of gaseous and liquid phases,... More
