Shale Gas in Place Calculation for a Single Well

Abstract

The aim of this study is to estimate total gas-in-place volumes for the Lower Paleozoic shale rocks, in part the Baltic Basin of northern part of Poland. For one of the projected horizontal well in Poland, the investigation was carried out. Based on published and literature date the authors built 3D static model which consist structural and parametric data needed for volumetric calculation. The input data include porosity, density, water saturation. The calculations for Polish conditions were compared with production data from North America and China. The analysis were provided for four examples. Based on available data and provided analysis of gas reserves for a single, depending on the fracking results, that the GIIP are changing. The quality and number the input data used to volumetric calculations plays a very big difference on gas resources. Graphics comparison between minimal Canadians and Polish , maximal Chinese (Longmaxi) and USA (Barnett Shale) shows statistical data.
