This data package with key Lower Paleozoic Baltic Basin samples assists

in predicting the relative volumes of gaseous and liquid phases, infering

migration pathways and predicting daughter compositions ahead of

drilling in the Baltic Basin. Data are also applicable to unconventional

petroleum exploration. The report 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 samples provides

insights into bulk petroleum property prediction.

GEOS4’S EXCLUSIVE PHASEFINDER TECHNOLOGY

This science-based technology accurately predicts charge timing, fluid volume and composition rapidly and inexpensively, based on calibrations from major petroleum provinces worldwide using PhaseKinetics*.

PhaseKinetics • kinetic parameters for timing predictions using slow heating rates,• Petroleum-Type Organofacies for predicting bulk petroleum types,• 2- and 4-component gas/oil ratio prediction in time and space,• 14-component physical property/PVT prediction in time and space,• kinetic data provided as tables as well as digital files for direct import

into PetroMod® (SLB) and Temis® (Beicip-Franlab).

Late Gas PotentialLate Gas Potential (>2%Ro) has profound implications for conventional and

especially unconventional gas prospects, in that significant additional charges

of methane can be expected to be generated from neo-formed thermally

stable moieties.TAKE ADVANTAGE OF APPROXIMATE 40% SAVING ON REGULAR PRICES WHEN YOU PURCHASE THIS PHASEFINDER

Lower Silurian shales are the main source rocks for conventional petroleum systems

in the Baltic Basin. Together with Cambrian and Ordovician shales, they provide

highly prospective sources also for unconventional oil and gas.

Two samples from the Silurian of Lithuania have been analysed following the

PhaseKinetics approach.

Additionally, first and second level screening data from Rock-Eval and pyrolysis gas

chromatography are supplied for 26 samples from Lithuania. For 8 of these samples

Late Gas Potential is determined.

GEOS4´s Baltic-Paleozoic PhaseFinder package allows the combination of source

specific compositional predictions of petroleum with petroleum system modelling.

The correct reproduction of petroleum phase behaviour represents a major step

forward in modelling fluid generation, migration and accumulation in this complex

setting.
