Resource assessment of Silurian and Ordovician shales in the Baltic basin based on the results of 3D geological modelling – methodological aspects

Abstract: The paper discusses issues of the estimation of hydrocarbon resources accumulated in shale formations. A general overview of the calculation methods used for these types of reservoirs has been presented, based on which two variants of the volumetric method for the calculation of petroleum and/or natural gas resources have been discussed. The second part of the paper presents an example of the use of the described methods for the region of prospecting for unconventional reservoirs in Silurian and Ordovician for… Show more

“…Formations Studied. The geological 3D model of the study area was developed on the basis of available data sets consist-ing of laboratory measurements, well logs, and seismic data (structural and seismic attributes) [27,28]. Geostatistical, variogram-based methods of rock property spatial variability modeling was applied [29,30].…”

“…Miąższość/objętość formacji łupkowej wstępnie określa potencjalną zasobność w węglowodory charakteryzowanego interwału (przy założeniu uśred-nionych parametrów skał łupkowych), natomiast przedział głębokościowy daje przesłanki dla określenia spodziewanego typu mediów złożowych, jak również pozwala na oszacowanie kosztów wiercenia otworów. Tak więc wyniki modelowania strukturalnego umożliwiają wykonanie wstępnej selekcji potencjalnych celów prac poszukiwawczych [4,5].…”
