The aim of the work was to analyze petroleum reservoir zone Lubiatów - Międzychód - Grotów (LMG), situated on the carbonate platform of the Grotów Peninsula in the north - western part of the Poland. Zechstein Main Dolomite is one of the most prospective areas economic accumulation of hydrocarbons in the Polish Lowlands. Based on the scientific of archives and documentation resulting attempt to assess the profile for source and petrophysical properties. Analysis of geochemical and petrological allowed for qualitative assessment of organic matter, the determination of its genetic type, the environment of deposition and the degree of thermal transformation. The results were used to calculate the volumetric method oil potential per unit volume of the Main Dolomite, also identified potential areas for the generation and accumulation of hydrocarbons while effectively sealing deposit.

Model strukturalno-parametryczny dolomitu głównego w rejonie Chartowa
(Data obrony: 2012-09-24) Bzymek, Tomasz
Wydział Geologii, Geofizyki i Ochrony Środowiska
Main Dolomite, occuring on the sulphate platforms of Polish Lowlands, is one of the most promising unit containing gas and oil. Getting acquainted with the sedimentation environment defining its diversified in thickness and facial character is crucial on the level of accurate characterisation of the platform areas and the distribution of areas representing potentially best reservoir features. In order to select the areas of best reservoir potential, the modeling of structural and parametrical platform structure of the Main Dolomite has been made in Petrel 2011 software. The results of the research include spatial petrophysical model and an interpretation of the potential reservoir areas of the Chartow carbonate platform.

Porównanie warunków strukturalnych, facjalnych, parametrycznych złóż węglowodorów Lubiatów i Międzychód
(Data obrony: 2014-09-30) Bińczyk, Szymon
Wydział Geologii, Geofizyki i Ochrony Środowiska
This paper contains description of the geological setting of the Lubiatow and Miedzychod hydrocarbon accumulation in the Main Dolomite deposits. In the thesis author also described geological settings of the Polish part of Zechstein Basin in reference to the European Zechstein Basin. Methodology of structural and parametric modelling in Schlumberger Petrel software is also described. Based on laboratory data, well logging, author created models showing the spatial distribution of clay content, porosity, natural spectral radiation variability, and also litofacial model. Prepared models allowed to determine area of the richest porosity parameters, and showing paleogeographic analysis based on natural radiation content from the spectral gamma ray profiles

Potencjał węglowodorowy dolomitu głównego w strefie złożowej Wysoka Kamieńska - Kamień Pomorski
(Data obrony: 2014-11-06) Wilk, Małgorzata
Wydział Geologii, Geofizyki i Ochrony Środowiska
The aim of the thesis was to analyze petroleum reservoir zone Wysoka Kamieńska – Kamień Pomorski. Based on the results of geochemical analyses 34 Main Dolomite profiles in the Kamień Pomorski carbonate platform and its adjacent area were characterized for source rock properties. A evaluation of the Main Dolomite quality was carried out on the geochemical indicators: especially total organic carbon content, its genetic types, the degree of thermal maturity and the environment of deposition. The obtained Ro values indicate that the carbonates reached the end of microbial phase generation and beginning of the „oil window” phase. The predominant type of kerogen in the analysed area was oil-prone kerogen (type II). Volumetric method enabled to calculate the hydrocarbon potential of Main Dolomite strata for individual paleogeographic zones.

The Racławka Valley - an example of an educational geosite related to the development of a Paleozoic carbonate platform
(Wydawnictwa AGH, 2016) Szczurek, Stanisław; Bąk, Marta; Dulemba, Paweł
The location and most interesting geological features of the Upper Devonian through Lower Carboniferous limestones in the Racławka Valley were presented. The limestones outcropped almost continuously along the natural valley cutting. They comprise over 60 million years of continuous growth of the carbonate platform, which developed on the ancient terrane – the Upper Silesian Block. Geosites described herein may constitute a destination for geological trips for undergraduate students of Environmental Sciences, where they can actively discover the development of an ancient carbonate platform and accompanied post depositional structures.

Układ faz węglowodorowych w obszarze złożowym Lubiatów - Międzychód - Grotów (LMG)
(Wydawnictwa AGH, 2008) Słupczyński, Kazimierz; Machowski, Grzegorz; Papiernik, Bartosz; Semyrka, Roman
For the Lubiatów - Sowia Góra - Międzychód - Grotów (LMG) hydrocarbon reservoir zone, situated within the area of the Main Dolomite carbonate platform and its foreland, interfacial surfaces between natural condensate gas and gas-saturated oil was determined applying the criterion of stable equilibrium in porous-fractured media filled with separate hydrocarbon phases. Hydraulic connection between individual hydrocarbon accumulations was proved. It was evidenced that narrow zones with Main Dolomite thickness less than 15 m and different hypsometric positions play the role of semi-permeable boundaries only. The determined surfaces between natural gas and crude oil considerably extend the accumulation zone in the area of the carbonate platform and its foreland.
