New report: Multi-component kinetics and late gas potential, Cooper Basin
September 11, 2015
Geoscience Australia released in September a report on multi-component kinetics and late gas potential of selected Cooper Basin source rocks. The study, executed by GEOS4, evaluated twenty-seven whole rock samples and eleven extracted samples or kerogen concentrates from five potential Permian sources within the Cooper Basin, Australia for petroleum...

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

AAPG: Where the action was in 2014
February 6, 2015
2014 was a year with a healthy dose of modest petroleum discoveries, according to the January issue of the AAPG Explorer. It wasn’t a standout year, exploration appeared to represent “more of a return to normal, to more typical years” Julie Wilson, senior exploration analyst for Wood Mackenzie in Houston was quoted. Where was the action? More
