In addition to CH4 and CO2, heavy hydrocarbons (e.g., C2H6 and C3H8) are frequently observed in carbonaceous fluid inclusions (i.e, wet gas inclusions with C-1/& sum;C-i < 0.95). However, determination of the composition of such complex volatiles is difficult based on traditional microthermometric measurements. Here we carried out experimental calibrations on Raman spectroscopic measurements of the pressure (P) and composition of the CH4 +/- C2H6 +/- C3H8 +/- H2S system at room temperature and 0.1-130 MPa. We confirmed that the C-H symmetric stretching vibration band of CH4 [nu(1)(CH4), similar to 2917 cm(-1)] shifted to lower wavenumber with rising pressure, thus the P-nu(1)(CH4) relationship could be applied to calculate the pressure of wet gas. It should be noted that the presence of C-2+ and/or H2S will shift the [nu(1)(CH4)] to lower wavenumber at constant pressure (with the order of C3H8 >= H2S > C2H6). Obviously, the P-nu(1)(CH4) relationship derived from pure CH4 system could not be simply applied to wet gas inclusion, otherwise the pressure would be overestimated. To avoid the overlap of the C-H vibrations of CH4, C2H6 and C3H8, the peak areas and peak heights of the overtone vibration of CH4 [2 nu(4)(CH4), similar to 2580 cm(-1)], C-C symmetric stretching vibrations of C2H6 [nu(3)(C2H6), similar to 995 cm(-1)] and C3H8 [nu(8)(C3H8), similar to 868 cm(-1)], and S-H symmetric stretching vibration of H2S [nu(1)(H2S), similar to 2612 cm(-1)] were fitted using Gaussian + Lorentz functions. The obtained peak areas and peak heights were then used to calculate the Raman quantification factors (F factor and G factor, respectively) of C2H6, C3H8 and H2S relative to CH4, respectively. Both the F factor and G factor increased with rising pressure, whereas the FC2H6, FC3H8 and GH(2)S kept nearly constant at similar to 5.69, 6.39 and 153.8, respectively in high pressure gas mixtures (e.g., >30 MPa). Therefore, for inclusions with higher internal pressure, the molar ratio of CH4, C2H6, C3H8 and H2S could be determined by the aforementioned F and G factors. This method was applied to the calcite-hosted single-phase gas inclusions in the Upper Permian Changxing Formation carbonate reservoir from the eastern Sichuan Basin (South China). Our results indicated that the trapping pressure would be obviously overestimated if the presence of heavy hydrocarbons was not taken into account.}, keywords = {raman spectroscopy; fluid inclusion; experimental calibration; wet gas; Trapping pressure}, year = {2024}, eissn = {1873-3557} } @article{MTMT:34112696, title = {Characteristics of fluid inclusions and analysis of hydrocarbon accumulation stages of Yan'an Formation in Wuqi area, Ordos Basin}, url = {https://m2.mtmt.hu/api/publication/34112696}, author = {Cheng, K. and Cui, J. and Meng, Z. and Liu, J. and Kang, Z. and Li, J.}, doi = {10.12029/gc20220102001}, journal-iso = {GEO CHINA}, journal = {ZHONGGUO DIZHI / GEOLOGY IN CHINA}, volume = {50}, unique-id = {34112696}, issn = {1000-3657}, year = {2023}, pages = {692-703} } @article{MTMT:33720723, title = {Localization of potential migration pathways inside a fractured metamorphic hydrocarbon reservoir using well log evaluation (Mezősas field, Pannonian Basin)}, url = {https://m2.mtmt.hu/api/publication/33720723}, author = {Hasan, Muhammad Luqman and M.

In order to accurately determine the hydrocarbon charging periods of Zhuhai Formation in Wenchang A Sag, the hydrocarbon inclusions and their associated brine inclusions in the sandstone reservoirs of Zhuhai Formation in the study area were taken as the research object. Fluorescence spectroscopy, laser Raman spectroscopy, micro thermometry and other related experiment were used, combined with the analysis of inclusion capture pressure calculation, burial history, paleogeothermal evolution history, and thermal evolution history of hydrocarbon source rocks. The research on hydrocarbon charging stages and their differences in the central depression and the fault zone has been carried out. The results show that there are three kinds of inclusions, including high‐density single‐phase oil inclusions, two‐phase of gas‐liquid hydrocarbon inclusions and two‐phase of gas‐liquid saline inclusions in the sandstonereservoir. The components of hydrocarbon inclusions and the associated brine inclusions are mainly CH4, C2H6, SO2, CO2 and H2O, and the homogenization temperature of brine inclusions distributed mainly from 95 to 180 ℃. Three stages of hydrocarbon filling occurred both in the central depression and the fault zone, but the hydrocarbon filling time is different. The first hydrocarbon charging occurred in the central depression rangesfrom 21.9 to 13.9 Ma, the second oil filling occurred at 12.0 to 8.9 Ma, and the third oil and gas filling occurred at 7.8 to 4.8 Ma. However, in the fault zone, the first oil charging occurred at 21.7 to 10.2 Ma, the second one occurred at 9.1 to 4.9 Ma, and the third oil and gas filling was about 3.9 to 1.5 Ma. The difference of source rock burial depth, multi‐stage fault activity and their spatio ‐ temporal configuration caused by different tectonic subsidence is the main reason for the difference of hydrocarbon generation peak and hydrocarbon accumulation time in the central depression and fault zone.

In this study, vein-bearing sedimentary rock samples from coal-bearing strata in the Huaibei coalfield were selected to reveal the fluid sources and the filling periods of CBM. The carbon source of the vein samples is a mixture of the degraded organic carbon of coal and the dissolution of carbonate minerals in coal measure. Considering the low salinity of the fluid, the infiltration of surface water will also bring some supergenic carbon supplement. Moreover, the high Sr-87/Sr-86 ratios might also be induced by the infiltration of surface water and the dissolution of radiogenic strontium adsorbed in coal. Based on the temperature, salinity, and Raman spectral analysis, the formation of fluid inclusions is divided into two phases: the first phase corresponded to the generation of large-scale thermogenic gas, while the second phase reflected the event of large-scale secondary biogas formation. The values of delta D-CH4 and delta C-13-CH4 in the group inclusions showed that no significant isotope fractionation occurred between the methane in the inclusions and that in the coal seam; the methane in the inclusions is predominantly biogas.

(i) For the syntaxial stage, the filling is dark and nonluminous, and the fluid captured by the overgrowing cement around the particles is mainly seawater; (ii) for the (Early) Mesogenetic burial stage, the calcite cement grows around the particles or micritic calcite matrix, and the fluid captured is mainly brine; (iii) for (Late) Mesogenetic burial stage, two sets of decomposed fissures developed in massive calcite colloids with non-luminous gas-rich hydrocarbon inclusions within the crystals; and (iv) for Telogenetic burial stage, weakly fluorescent pure gaseous hydrocarbon inclusions are developed in luminescent calcite veins. The result indicates that the organic inclusions in the Lower Carboniferous of the central Hunan Basin are dominated by weakly fluorescent and nonfluorescent rich gas inclusions and pure gas-phase inclusions, with three stages of hydrocarbon filling.

Fluid inclusions and pore fluid microthermometric data of 37 samples from clastic reservoir in the Wulan-Hua Sag are available for detailed correlation and analysis. The reconstructed erosion thickness indicates that first of all, differential uplift that is characterized by seesaw uplift-erosion initiated at the north sub-sag. Secondly, largest erosion degree appears in Tumu'er and Saiwusu tectonic belts. Thirdly, the thickness of sedimentary rocks removed by erosion in the south sub-sag progressively increases from its subsiding centre outwardly. Burial history of the Wulan-Hua Sag belongs to type of late-period intensive uplift-erosion. Two types of fluid inclusion are recognized in the Wulan-Hua Sag indicating two hydrocarbon accumulation periods for reservoirs in LK(1)bt(1) (lower interval in first member of Tengge'er Formation), which is middle depositing period of K(1)bt(1) (first member of Tengge'er Formation) to early depositing period of K(1)bt(2) (second member of Tengge'er Formation) and early K(1)bt(2) to middle K(1)bs (Saihantala Formation) depositing period, respectively.

However, the mechanism that controls the formation of natural fractures in tight reservoirs remains controversial. This study investigates natural fractures within carbonate-rich tight oil reservoirs from the Permian Lucaogou Formation in the Jimsar Sag, southern Junggar Basin. Drill core and image log observations show that fractures in the Lucaogou Formation can be categorized into two types: beddingparallel fractures and inclined fractures. The carbon and oxygen isotopic compositions of calcite cements in the bedding-parallel fractures range from 0.6 parts per thousand to 6.0 parts per thousand (delta C-13(PDB)), and from -15.5 parts per thousand to -8.9 parts per thousand (delta O-18(PDB)), respectively, which are similar to those of the organic-rich host rock. This suggests that the bedding-parallel fractures likely formed in a closed fluid system. Fluid inclusion analyses of the aqueous inclusions in calcite cements from the bedding-parallel fractures record homogenization temperatures of 91.5 degrees C-130.4 degrees C, indicating that they formed at the Cretaceous to Cenozoic, during when the Lucaogou Formation reached peak oil generation stage. Therefore, the bedding-parallel fractures were most likely generated by hydrocarbon generation overpressure. The presence of hydrocarbon inclusions in bedding-parallel fracture cements supports natural fracturing by high pore-fluid pressure. The delta C-13(PDB) and delta O-18(PDB) of calcite cements within the inclined fractures vary from 3.6 parts per thousand to 9.6 parts per thousand, and from -11.0 parts per thousand to -2.9%, respectively, which are close to those of the carbonaterich parent rock. This also supports a closed fluid system scenario. The relatively lower fluid inclusion trapping temperatures (70.5 degrees C-109.7 degrees C) suggest that they were likely generated by decrease of confining stress during uplift processes. Therefore, both an increase in pore-fluid pressure and a decrease in confining stress contribute to the formation of natural fractures in the Lucaogou Formation tight oil reservoirs.}, keywords = {Tight reservoir; opening mechanism; Bedding-parallel fractures; Fluid inclusion microthermometry; C-O isotope}, year = {2020}, eissn = {1873-4073} } @article{MTMT:31725808, title = {Natural Fractures in Carbonate Basement Reservoirs of the Jizhong Sub-Basin, Bohai Bay Basin, China: Key Aspects Favoring Oil Production}, url = {https://m2.mtmt.hu/api/publication/31725808}, author = {Liu, Guoping and Zeng, Lianbo and Han, Chunyuan and Ostadhassan, Mehdi and Lyu, Wenya and Wang, Qiqi and Zhu, Jiangwei and Hou, Fengxiang}, doi = {10.3390/en13184635}, journal-iso = {ENERGIES}, journal = {ENERGIES}, volume = {13}, unique-id = {31725808}, issn = {1996-1073}, abstract = {Analysis of natural fractures is essential for understanding the heterogeneity of basement reservoirs with carbonate rocks since natural fractures significantly control key attributes such as porosity and permeability. Based on the observations and analyses of outcrops, cores, borehole image logs, and thin sections from the Mesoproterozoic to Lower Paleozoic in the Jizhong Sub-Basin, natural fractures are found to be abundant in genetic types (tectonic, pressure-solution, and dissolution) in these reservoirs. Tectonic fractures are dominant in such reservoirs, and lithology, mechanical stratigraphy, and faults are major influencing factors for the development of fractures. Dolostones with higher dolomite content are more likely to have tectonic fractures than limestones with higher calcite content. Most tectonic fractures are developed inside mechanical units and terminate at the unit interface at nearly perpendicular or high angles. Also, where a thinner mechanical unit is observed, tectonic fractures are more frequent with a small height. Furthermore, the dominant direction of tectonic fractures is sub-parallel to the fault direction or oblique at a small angle. In addition, integrating diverse characteristics of opening-mode fractures and well-testing data with oil production shows that, in perforated intervals where dolostone and limestone are interstratified or dolostone is the main lithologic composition, fractures are developed well, and the oil production is higher. Moreover, fractures with a larger dip angle have bigger apertures and contribute more to oil production.

Based on the analyses of outcrops, cores, thin sections, imaging logs, and laboratory measurements, tectonic fractures are the dominant type of natural fractures, and their development is mainly influenced by petrology and faulting. Tectonic fractures are more developed in metamorphic rocks with a higher content of brittle minerals, while fracture orientations are primarily parallel or almost parallel to the fault strikes. Opening-mode fractures, which account for more than 65% of the total reservoir porosity, provide the primary storage space for metamorphic basement reservoirs. Besides, opening-mode fractures serve as the major pathways for fluid flow throughout the reservoirs and ultimately determine the quality of these reservoirs. Therefore, the discrepancies in fracture development are speculated to be the primary reason leading to the vertical stratification of reservoirs. According to the degree of fracture development, various rock types in metamorphic basement reservoirs can be arranged in order as leptite, granulite, migmatitic granite, gneiss, lamprophyre, diabase, and amphibolite. In this sequence, the former rocks are more likely to become effective reservoirs, while the latter ones are usually inner interlayers. However, the lithology boundary of reservoir rocks and inner interlayers is not definite in this sequence. In a specific metamorphic basement reservoir, the rocks that can become reservoirs have a lower limit in the sequence.

However, the hydrocarbon migration and accumulation histories of this reservoir have not been thoroughly elucidated and urgently require further research. Fluid inclusions offer a unique and useful method to test for hydrocarbon migration, accumulation, composition and timing. This study integrated the hydrocarbon charge history using fluid inclusions in the Lower Cambrian to Neoproterozoic reservoir from the Micangshan tectonic zone. This work involves the delineation and analysis of fluid inclusions using the petrography, spectroscopy and microthermometry of fluid inclusions. Based on the fluid inclusion analyses combined with reservoir thermal history, timing estimates and charge models of the hydrocarbons were obtained. The formation of natural gas was multifactorial in the Lower Cambrian to Neoproterozoic petroleum system, and the gas in the Niutitang (epsilon(1)n) and Dengying (Z(2)d) reservoirs was mainly from oil cracking and dry gas, and gas in the Xiannvdong (epsilon(1)x) and Canglangpu (epsilon(1)c) reservoirs was abiogenic and formed in hydrothermal fluids by regional tectonothermal events. Three well-defined stages of hydrocarbon charge were identified in the petroleum system in the Micangshan tectonic zone. The stage of oil charge first began before the Early Permian (similar to 277 Ma); the stage of gas charge from oil cracking occurred in the Late Triassic to Early Jurassic (212 Ma-198 Ma); and the stage of gas charge from dry gas occurred in the Middle Jurassic (173 Ma-166 Ma). The gas of mixed origin from the Niutitang reservoir was stored in the nanoscale pores as a self-reservoir, rather than as an effective gas source for the overlying reservoirs. (C) 2020 The Authors.

In the past few decades, scholars at home and abroad have conducted a large number of exploratory studies on the dating of hydrocarbon accumulation, and gradually formed the petroleum accumulation geochronology. As a branch of petroleum geology, based on systematic investigations, the author believes that the formation and development of petroleum accumulation geochronology has gone through three main stages: qualitative description stage, semi-quantitative description stage, quantitative characterization stage.

In plants, photosystems (PSI and PSII) are heterogeneously distributed between granal and stromal thylakoids. Here we have described similar heterogeneity in the PSI, PSII, and Phycobilisomes (PBS) distribution in cyanobacteria thylakoids into microdomains by applying a new image processing method suitable for the Synechocystis sp. PCC6803 strain with YFP-tagged PSI. The new image processing method is able to analyze fluorescence ratios of PPCs on single cell level, pixel per pixel. Each cell pixel is plotted in CIE1931 color space by forming a pixel-color distribution of the cell. The most common position in CIE1931 is then defined as protein arrangement (PA) factor with x-y coordinates. The PA-factor represents the most abundant fluorescence ratio of PSI/PSII/PBS, the "mode color" of studied cell. We proved that a shift of the PA-factor from the center of the cell-pixel distribution (the "median" cell color) is an indicator of the presence of special subcellular microdomain(s) with a unique PSI/PSII/PBS fluorescence ratio in comparison to other parts of the cell. Further, during a 6 hour high-light (HL) treatment, "median" and "mode" color (PA-factor) of the cell changed similarly on the population level, indicating that such microdomains with unique PSI/PSII/PBS fluorescence were not formed during HL (i.e. fluorescence changed equally in the whole cell). However, the PA-factor was very sensitive in characterizing fluorescence ratios of PSI/PSII/PBS in cyanobacterial cells during HL by depicting a 4-phase acclimation to HL and their physiological interpretation has been discussed.

These "diamond" quartz record the migration of hydrothermal silica-rich brines and associated hydrocarbons that recorded a temperature increase (outlined by fluid inclusion studies) from similar to 90 to similar to 140 degrees C. This gradient is also recorded by a change in the organic matter species trapped in quartz, from bitumen located in the inner quartz growth zones to liquid hydrocarbons trapped within the outer quartz overgrowths. Secondary ion mass spectrometer (SIMS) oxygen isotope microanalyses allowed to differentiate two delta O-18(H2O) values corresponding to the oil-dominated zone (core) and the water-dominated zone (outer growth zone). The heavier delta O-18(H2O) values in the water-dominated zone do not only record a higher temperature of formation, but also an increase in the delta O-18(H2O) of the parental fluid. Isotopic compositions of diamond quartz suggest a heterogeneous source of surficial fluids and formation-waters expelled from clays tones.Within the basin history, the diamond quartz precipitation took place during early Jurassic to Eocene subsidence periods.

Insights into palaeo fluid compositions complement observations on present day fluid compositions, which represent only the end-point of complex cumulative processes throughout basin history. In this contribution, we review a wide range of approaches used to extract geochemical information from petroleum inclusions, and how these can be used to better constrain petroleum systems. These techniques can be grouped into optical, spectrographic and thermometric non-destructive methods, or destructive chemical analyses of bulk samples or individual inclusions.Typically optical methods documenting the distribution and visual properties of petroleum inclusions are used to provide petrographic context for subsequent specialised geochemical analyses of petroleum inclusions. Additional non-destructive techniques such as Raman spectroscopy can then be applied to provide some further insights into the composition of the trapped fluids, although the complex nature of petroleum generally requires direct access to the fluid for a more complete understanding of geochemical aspects. A variety of destructive techniques have been developed, initially to analyse bulk samples released by mechanical crushing and more recently through ablation type techniques that allow the composition of individual inclusions to be characterised.Screening geochemical techniques that utilise mechanical crushing of bulk samples to analyse petroleum inclusions using mass spectrometry without prior chromatographic separation have become routine analyses. Other geochemical techniques more geared towards detailed molecular information such as biomarkers utilise chromatographic separation prior to mass spectrometry. Evaluation of the isotopic composition of petroleum inclusions is also possible for both bulk samples and compound specific analyses.The use of lasers to open individual inclusions allows the released contents to be analysed by thermal extraction-gas chromatography-mass spectrometry (GC-MS), or mass spectrometric mapping of minerals using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), a surface-sensitive analytical method that uses ion beams to ablate into minerals.The continued evolution of techniques to analyse the incredibly small volume of hydrocarbons trapped within fluid inclusions has progressed to a point where there is little that can be done to evaluate a live oil or gas sample that cannot be achieved for a fluid inclusion sample. The full power for tracing petroleum systems is, however, only realised where there is an effective integration of fluid inclusion data with a more conventional approach to petroleum systems analysis.

The hydrocarbon accumulation periods were defined by analyzing the hydrocarbon-generating history of source rocks. The results indicate that the hydrocarbon inclusions can be divided into two phases. The first phase is located in the carbonate cements and the fractures within quartz grains with characteristic yellow fluorescence, high salinity and high density. The homogenization temperature of brine inclusions is from 90 ℃ to 100 ℃. The second phase is located in the dissolution fractures of feldspar and fractures through quartz grains with blue-green fluorescence, low salinity and low density.The homogenization temperature is mainly from 120 ℃ to 140 ℃.There are two major hydrocarbon-generating stages: the Dongying deposition period and the late Guantao deposition period to the Minghuazhen deposition period.The Minghuazhen deposition period is the major stage.A two-period hydrocarbon accumulation is identified in Paleogene reservoirs. The first period is from the late Dongying deposition period to the early uplift stage, and the second is from the late Guantao deposition period to the Minghuazhen deposition period. Controlled by the thermal evolution and hydrocarbon-generating history of source rocks, the accumulation periods of different parts and layers are different. Petroleum reservoirs generated in the early period are mainly distributed in the source rock layers in the center of hydrocarbon-generating sags. Reservoirs generated in the second period cover all the area which is the main accumulation period.The upper layers are characterized with late accumulation period, while the lower with two periods. © 2018, Periodical Office of China University of Petroleum.

The multipeak distribution of homogenous temperature of the brine inclusions showed that the inclusions captured should be multiperiod fluids at various depths. Comparison of the homogeneous temperature of brine inclusions with the temperature on the burial history curve suggested that the source rocks had entered the stage of large-scale hydrocarbon generation. However, only individual brine inclusions containing methane were found, and no oil-bearing inclusions were seen. The absence of oil-bearing inclusions indicated that no large-scale oil charges and limited favorable mature source rocks were present in the study area. The paleosalinity varied with depth and was divided into three zones, namely two low-value zones in the shallow and deep burial and one high-value zone in the medium burial. The secondary pores were relatively developed in the high-salinity fluid zone. Secondary pores are chiefly related to the inorganic acid associated with dehydration and mutual transformation of clay materials, and to the organic acid released from limited mature organic matter.}, keywords = {EVOLUTION; fluid inclusion; Energy & Fuels; Engineering, Chemical; homogeneous temperature; paleosalinity; Hydrocarbon charge history}, year = {2014}, eissn = {1532-2459}, pages = {2911-2920} } @{MTMT:33767201, title = {Petroleum Hydrocarbon Analysis}, url = {https://m2.mtmt.hu/api/publication/33767201}, author = {Falcó, I.P.R.}, booktitle = {Handbook of Water Analysis: Third Edition}, doi = {10.1201/b15314-34}, unique-id = {33767201}, abstract = {Petroleum is a word that comes from the Greek word petros (rock) and Latin word oleum or Greek elaion (oil), so petroleum means “rock oil.” Petroleum is the most important source of energy and one of the main chemical industries in the world, and it is expected to remain so over the next decades. Petroleum is a complex mixture of different organic compounds or hydrocarbons. These compounds are formed mainly from carbon and hydrogen elements with different length of chain or number of aromatic rings going from light gases to heavy residues. Other elements are present in lower proportion such as sulfur, oxygen, and nitrogen, or metals to a lower extent. Petroleum hydrocarbons, a term used to refer to crude oil and the rened products from it, are usually obtained from distillation of crude oil. The nal product composition depends on the crude oil source and the rening process used to produce it, so it varies, not only among the product types, but also within each product type. © 2014 by Taylor and Francis Group, LLC.}, year = {2013}, pages = {845-868} } @mastersthesis{MTMT:34621508, title = {Hydrodynamic and Heat Transport Modeling of Underground Fluid Reservoirs Based on a Complex Crack Network Analysis Method}, url = {https://m2.mtmt.hu/api/publication/34621508}, isbn = {9798381043129}, author = {István, Vass}, unique-id = {34621508}, year = {2013} } @article{MTMT:2190426, title = {Integrated core study of a fractured metamorphic HC-reservoir; Kiskunhalas-NE, Pannonian Basin}, url = {https://m2.mtmt.hu/api/publication/2190426}, author = {Fiser-Nagy, Ágnes and M.
