SEDIMENTOLOGY
Reconstructing past environments is crucial in understanding petroleum or ore-deposits systems. Our sedimentological service offers a comprehensive analysis of the sedimentary environments and further integration with available petrophysical, geophysical, geochemical, and stratigraphical data.
Our approach includes:
a) lithofacies and facies associations recognition,
b) reconstructing palaeoenvironments,
c) recognising sedimentary textures and structures,
d) ichnofabric analysis, and ichnotaxonomy (shallow- and deep-water ichnology following prof. Alfred Uchman's and Knaust methods).
e) integration with geochemical and mineralogical data (including bulk quantitative mineralogy - a technique developed by Środoń et al., 2001)
f) Well correlations
g) Data mining and geostatistics
Sedimentological data is then confronted with petrophysical data in order to understand factors controlling reservoir quality. Sedimentological data can be also supplemented by petrography. Thin section analysis allows reconstructing the diagenetic history of the siliciclastic or carbonate intervals.
