ABSTRACT

Paper presents results of 3D modeling and unconventional hydrocarbon resources assessment in the central part of Lublin Basin (south east Poland). Modeling was performed for Lower Paleozoic strata using Petrel software. Input data set comprised well logs, laboratory measurements including RockEval pyrolysis, 2D and 3D seismic survey and their interpretation, results of 1D modeling in BasinMod. Spatial modeling was performed on semi-regional scale. The structural framework of semi-regional model was created based on 51 faults on the area of 7340 km2. It consist of 120 geological layers and it is divided into 8 zones from the top Cambrian to the top of Silurian. Parametric modeling included such parameters as thickness, bulk density (RHOB), porosity (PHI), water saturation (Sw), vitrinite reflectance (Ro), shale and brittle minerals volumes. For hydrocarbon resources assessment was performed reflectivity model, that allowed establishing zones of hydrocarbon generation, as well as estimation of original content of organic carbon (TOCp), the generation potential expressed as the parameters from RockEval pyrolytic analysis - Hydogen Index (HI) and average generation potential (S1+S2). Preliminary resources assessment for oil, liquid and gas window was performed using equations of modified Schmoker method. Hydrocarbon resources were calculated separately for Caradoc, Llandovery and Wenlock strata in each hydrocarbon generation window. The most productive interval in the area is Wenlock. Resources are presented as GIIP.

Keywords: 3D modeling, unconventional resources, Schmoker method, parametric modeling
