Principal research interests:

+ Sedimentology (facies interpretation, sedimentology and palaeogeomorphology of terrestial environemnts)
Projects: Permian-Triassic from Holy Cross Mountains. Upper Triassic from Poland and Alps; Carboniferous from Poland and the UK; Ordovician/Silurian from the UK, Poland and Czech Republic.

+ Inorganic Geochemistry (chemostratigraphy, modelling of bulk mineralogy and petrophysical parameters from elemental analysis and wireline and MWD/LWD/PWD logs - utilizing the linear and non-linear and neural networking optimization engines). Projects from Europe, USA, Canada, Africa and Middle East.

+ Stratigraphy (I have an extensive experience in chemostratigraphy, lithostratigraphy, magnetostratigraphy and sequence stratigraphy). Projects from the Central Europe (Germanic Basin, Paris Basin, Southern Permian Basin, Shale-Gas plays in Poland, Carpathians and Alpine Foreland Basins, Carboniferous basin), the North Sea (Northern Permian Basin: North, Central and Southern North Sea) and Middle East (Arabian Platform), Gulf of Mexico (sub Salt), South America. Experience in siliciclastic and carbonate sequences.

Additionaly I am working as consultant geoscientists in O&G upstream. For many years my interests have been focused on broad aspects on reservoir geology including sedimentology, stratigraphy and petrophysics. Currently working as real time pore pressure/geomechanics analyst:

+ Pore Pressure evaluation (Real-time analysis: Eaton, Bower and Miller models, gas analysis). Projects from the UK, Norway, Dennmark, USA, Brunei, Mauritania, Senegal, Suriname, Ivory Coast, Falkland Islands, Maynmar. 

+ Formation Evaluation (wireline data analysis and modeling reservoir quality). Projects from onshore Europe, North Sea, Canada and Africa.

Offshore and onshore experience (including HPHT, shale and tight gas plays): The North Sea, Suriname, onshore UK, onshore France, onshore Poland.
