(Wydawnictwa AGH, 2019) Dudek, Jacek; Podsobiński, Daniel; Potera, Krzysztof; Kawecki, Bartłomiej; Paliborek, Grzegorz; Pietrzyk, Krzysztof; Wójcik, Piotr
Nowadays, because of the smaller and smaller chances of discovering new hydrocarbon deposits with abundant resources as well as significant technological advance, the proper strategy of reservoir management connected with simultaneous optimization of its production parameters is the key element in the process of development the most economically advantageous variant of reservoir management and field development. In Polish Oil and Gas Company, the project called as »Digital reservoir« based on the interactive IAM platform was initiated, thanks to which the work of all upstream segments was integrated, starting from geophysics, geology through reservoir engineering, production engineering, process engineering ending with the economic model that allows for verification of the economic efficiency of the investment. This paper presents the methodology of integration all of the above elements and the results of the IAM system implementation with further production forecasts, on the example of selected natural gas reservoirs in the Polish Lowlands being PGNiG S.A. assets.

The fluid flow modeling procedure including a critically stressed fracture analysis of coalbed methane reservoir: a case study of Upper Silesian Coal Basin, Poland
(Wydawnictwa AGH, 2023) Kępiński, Michał; Ryder, Paweł; Dudek, Jacek; Podsobiński, Daniel
The geomechanical modeling turned out to be an essential component of the hydrocarbon exploration assisting reduction of risk of drilling issues and optimization of hydraulic fracturing treatment. This study provides a workflow of critically stressed fracture (CSF) analysis dedicated for coal layers. The main focus of the paper is applying the 1D mechanical models and following modelling of hydraulic fracturing treatment to describe the fracture behavior under the impact of the stresses at the wellbore scale. Another objective of presented study is demonstration of benefits of 1D and 3D CSF analysis to understand fracture contribution to gained volume of hydrocarbon after fracturing of coal seam. Interpretation of fracture orientation and their behavior is vital to effective development of coal bed methane (CBM) resources as the CSF can be responsible for considerable part of CBM production. Natural fractures and faults contribute to fluid flow through rock. It is often noted that natural fractures may not be critically stressed at ambient stress state. However, during stimulation the optimally oriented natural fracture sets have an inclination to become critically stressed. Hence, understanding of the recent stress state and fracture orientations is significant for well planning and fracturing design. The outcome of this study are comprehensive 1D mechanical Earth models (MEMs) for analyzed wells and explanation of behavior of identified CSF under variable stress state as well as understanding of the connectivity of natural fractures within zone subjected to fracturing treatment.

The use of computer simulations to assess the effectiveness of the revitalization of mature oil fields using the selected reservoir as an example
(2017) Podsobiński, Daniel; Stopa, Jerzy; Wojnarowski, Paweł
The decrease in new oil field discoveries over the years makes it necessary to return to the abandoned partially depleted oil fields. Due to remaining significant amount of geological resources, mature oil field can be important in the overall balance. The production rate can be increased using various recovery methods. This paper presents a method of revitalizing mature oil fields used in Poland and wide world as well as screening criteria were presented. This article indicate the role of computer simulation as a tool in planning process of revitalization works in case of mature oil fields exploration and management. A recovery methods would be proposed, using computer simulation for the selected reservoir in south – eastern Poland as an example. The effectiveness of the recovery method would be determined through forecast of future production. An preliminary economic analysis would be performed to determine the feasibility of the seletected method taking into account the initial investment costs and different oil prices.
