Geomechanical modellingl of Paleozoic Shale Gas Formation: a case study from the Baltic Basin, northern Poland
Journal Title: Geology, Geophysics & Environment - Year 2017, Vol 43, Issue 3
Abstract
Geomechanical modeling has become a powerful tool for optimization of well placement and trajectories, designing drilling processes and stimulation of reservoir formation as well as effective reservoir management. In this paper we present the results of 3D geomechanical modeling carried out in an onshore area within the Baltic Basin, northern Poland, where the Silurian and Ordovician shale formations are the exploration targets. The fundamental elements of the methodology, processes, and available datasets used in the modelling are discussed. The petrophysical, elastic, and mechanic properties of the rock were applied in the modelling process, along with the principal stresses and pore pressure in the geological formation. Moreover, the main calculation methods and data requirements for the Mechanical Earth Model construction are discussed. A comprehensive 3D geomechanical model was constructed, providing important information to engineers and decision makers. The model can identify zones within the area of interest of higher potential in terms of efficient stimulation treatment design.
