PhD thesis presents application of time-frequency methods to acoustic full waveforms (AFW) processing. The goals of the research are: precise determination of acoustic waves from AFW, wave field decomposition into separate waves and pointing out zones of different elastic parameters. First part of the thesis includes: theoretical background of time-frequency methods, information on full waveform acoustic logs and brief description of the data. Second part is devoted to detailed description of time-frequency analyses of acoustic full waveforms. Discrete and continuous wavelet transform and matching pursuit algorithm are applied to AFW. Simulations, methodology and results of each method are discussed in detail. From proposed methods matching pursuit reveals the best resolution and makes wave extraction possible. Results are used for transit interval time calculation, which are compared with the counterpart parameters obtained from the original waveforms (i.e. not decomposed with matching pursuit). Additionally, decompositions are used for determination of frequency content of each wave packet. Time-frequency representations of AWF are also used to improving qualitative interpretation. On the basis of continuous wavelet transform time-depth-frequency plots for a given frequency are constructed. What is more, continuous wavelet transform and matching pursuit decomposition are used to calculating instantaneous attributes that indicate local changes of geological formation. Presented research is a kind of methodological work. Developed procedures are innovative and universal.

The paper presents an analysis of the acoustic wave forms obtained for the four holes located within the Przedkarpackie foredeep. In order to process and interpret the results of measurement GeoWin system was used (FWS Wave 2 application). Obtained value of compressional and shear waves velocity together with the velocity of Stoneley waves as well as the calculated Vp / Vs ratio allowed for the interpretation of the geological structure of the given rock centers. Designated interval times of the P and S waves with density profiling also enabled the determination of dynamic elastic modulus of rock. A juxtaposition of the dependency of velocity and bulk modules on the value of the Vp/Vs ratio, porosity and clay volume was made. On the basis of the results of the research the conclusions about the lithology, porosity and fracturing, as well as elastic and reservoir properties of rocks were drawn.

In order to characterize the influence of petrophysical parameters on permeability of rocks, statistical analysis was performed on core data which includes porosity, permeability, density and the percentage of calcium carbonate content. Characteristics of porosity, permeability and the Flow Zone Indicator (FZI) have been presented. There were discovered differences in FZI between the hydrocarbon-bearing sections and the unproductive beds of the well Nowosielec-3, and between reservoir rocks and vaste rocks of the wells Jata-1 and Kończyce-1. A division of data set due to the FZI has been realized and statistical relations between permeability and porosity in homogeneous flow units have been established. Relations describing a mobility of media in pore space for FZI units appeared to be stronger than for the total data set. In order to estimate the effectiveness of Zawisza’s formula for the calculation of permeability in the profile of a well, a comparison has been made between the permeability, estimated through the usage of Zawisza’s formula in the process of the comprehensive interpretation of logs, and between the permeability from cores.

Wydział Geologii, Geofizyki i Ochrony Środowiska
W pracy opisano przyczyny radialnych zmian porowatości neutronowej, FN, uzyskanej ze zliczeń detektorów w kompensacyjnych sondach neutronowych. Analizę czynników wpływających na charakter profilowań neutronowych w kierunku poziomym przeprowadzono na bazie danych z czterech otworów wiertniczych znajdujących się w różnych częściach zapadliska przedkarpackiego, przewiercających mioceńską formację skalną typu cienkie warstwy. Przedyskutowano przyczyny takiego zjawiska, uwzględniając obecność stref pierścieniowych wokół otworu, związanych z wnikaniem płuczki wiertniczej do skał otaczających otwór, wpływ cienkich warstw na wskazania sond, rolę kroku próbkowania oraz zasięgu radialnego poszczególnych sond. Dzięki wykorzystaniu odpowiednio dobranych pod względem zasięgu radialnego i rozdzielczości pionowej pomiarów sondą HRAI, upadomierzem i sondą gęstościową, uzupełniających profilowania neutronowe, wydzielono interwały o charakterze piaskowcowym, nasyconych wodą złożową bądź gazem, oraz warstwy o charakterze mułowcowo-iłowcowym w każdym z otworów i przeanalizowano dla nich rozkład porowatości neutronowych w kierunku radialnym.

Attempts to calculate the pseudo-anisotropy of elastic parameters of shales gas formations based on well logging data and their geostatistical analysis
(Wydawnictwa AGH, 2019) Bała, Maria; Cichy, Adam; Wasilewska-Błaszczyk, Monika
This paper presents the attempts to calculate the pseudo-anisotropy of elastic parameters for the Silurian and Ordovician shale formations of several wells located in the Baltic basin. For this purpose, well-logging data were used, in particular data recorded with acoustic dipole tools. With the P and S waves velocities available, measured at the dipole setting in two orthogonal directions XX or YY (S$_{Fast}$ and S$_{Slow}$), the elastic $\varepsilon$ and $\gamma$ parameters were calculated. In this paper we evaluate the effect of different factors e.g., porosity, clay and kerogen content on the velocity of anisotropy shale gas formations. A geostatistical analysis of elastic and reservoir properties was carried out in order to determine the character of the variability of Silurian and Ordovician shale formations in all of the studied wells. Semivariograms for each well characterizing the variation of elastic parameters in the vertical direction were calculated.

Badanie wpływu anizotropii i zailenia na prędkości rozchodzenia się fal podłużnych i poprzecznych oraz innych parametrów sprężystych skał klastycznych
(Wydawnictwa AGH, 2009) Bała, Maria
Rock anisotropy has a significant effect on longitudinal and shear wave velocities, that are measured in acoustic logging. This can affect both a single layer (then it is related to the microstucture) and a sequence of layers (a large scale). This paper discusses elastic components of anisotropic media with so-called transverse isotropy (TI) and Thomsen coefficients characterizing the P-wave and S-wave anisotropy and $V_{P}/V_{S}$ ratio. The effect of shale rock content on parameters measured in acoustic logging was also studied.

Integrated reservoir characterization for fluid flow modeling of the gas deposit at the Carpathian foredeep
(Data obrony: 2011-10-03) Ha Quang, Man
Wydział Geologii, Geofizyki i Ochrony Środowiska
In the dissertation, the petrophysical and geophysical characteristics of the selected gas deposit in the Carpathian Foredeep was presented and geostatistical approach was proposed for seismic facies modeling and fluid flow modeling in die gas deposit when limited number of data is available. The main goal of the research was focused on scaling geological and geophysical data from various sources: point-type results of laboratory measurements (micro scale), one-dimensional well logging data (mezo scale) and 2D seismic data (macro scale) for improving the description of the deposit and for construction of proper static three- dimensional model for dynamic fluid flow modeling in the gas deposit. The gas deposit from the north-eastern part of the Carpathian Foredeep from the sandy-shaly thinly-bedded Sarmatian formation was selected for the research due to great amount and availability of geological data, and results of laboratory measurements, and well logging with their comprehensive interpretation results and 2D seismic data, and also due to good recognition of structural and sedimentation conditions. The division of the reservoir rock into units with homogeneous ability to media flow obtained on thę basis of laboratory data and well logging data can be recognized as the original result of the research together with the expanding of this one-dimensional pattern to three- dimensional structure of deposit. Also, original methodology of construction of pseudo 3D seismics on the basis of dense network of 2D seismics was elaborated using statistical methods.
