Abstract

The purpose of the work is to assess the reliability of the results of geological and geophysical studies of complex-constructed Neogene deposits by electrical methods and to develop optimally reliable approaches to the selection of hydrocarbon-saturated rocks with an assessment of their reservoir parameters. In addition, to establish the factors that affect the ambiguity of geological and geophysical conclusions in the process of research of complex lithological and stratigraphic strata, which ultimately causes the omission of reservoir rocks saturated with hydrocarbons. The obtained experimental results of the research of the core material taken from the wells of the adjacent gas condensate fields made it possible to identify the main factors and parameters that determine the filtration-capacity parameters of Neogene deposits. Based on the above, there is a need to substantiate and develop methodological aspects of the use of electrical methods to determine the nature of reservoir rock saturation and to determine the dynamics of water-gas-condensate contacts. The subject of research is the electrical parameters of water- and gas-saturated reservoir rocks. In addition, the substantiation of the effect of pressure and temperature on the performance of electrical methods in the process of researching complex-constructed Neogene reservoir rocks and the peculiarities of the dynamics of changes in water-oil and gas-water contacts. The decrease in oil and gas production from complex geological sections is due to both economic and technological factors that arise in the process of researching the lithological and stratigraphic strata of the Bilche-Volytsa zone. The geological structure of the above-mentioned territories is extremely complex and represents, in particular in the Bilche-Volitsa zone, a classically expressed wing of the platform type, weakly dislocated by upper Miocene molasses.

Abstract

The Middle Devonian deposits within the Lviv Depression of the Volyn-Podillya plate are largely underexplored and are of great interest for further exploration for hydrocarbons. The presence of two discovered gas fields and the occurrence of granular and fractured reservoir rocks within the entire Lviv Depression point that the deposits of this age range are prospective for further exploration works for hydrocarbons. The authors conducted mineralogical and petrographic studies of these strata in order to study different types of reservoir rocks.

Petrographic studies of terrigenous rocks showed that the reservoir rocks are composed of fine-grained and medium-grained sandstones, as well as fine-grained and coarse-grained siltstones. The matrix in these rocks is contact-porous and contact, composed of dolomitized calcite (4–19 %) and hydromica (3–13 %). Regardless of the type of matrix, the pore space in rocks is formed by intergranular spaces of 0.05 to 0.5 mm size. Siltstone-sandstone deposits represent the granular-type reservoir rocks, the filtration properties of which are formed by the intergranular space, while fractures are of subordinate importance. Terrigenous rocks form gas-bearing horizons in Middle Devonian (Eiffelian and Zhivetian) in the Lokachi field of the Lviv Depression. Carbonate rocks are represented by a wide range of lithological types from slightly dolomitized biodetrital limestones to secondary dolomites. Dolomitization and recrystallization form fracture-like microcaverns with a size of up to 0.5 mm and result in a high porosity of up to 9 %. In carbonate reservoir rocks fracturing is prevailing, while porosity has a subordinate value.

Studies of the molecular composition of natural gases from reservoir rocks of the Middle Devonian of the Lokachi field showed that their predominant component is methane. Its content is 92.7–95.4 vol %. The rest of the methane homologues account for 1.45–2.16 vol %. The total share of non-hydrocarbon gases – nitrogen, carbon dioxide, helium and hydrogen are 3.102–5.082 vol %.

In order to clarify the origin of the Middle Devonian gases of the Lviv Depression, further studies of the carbon, nitrogen, and hydrogen isotopic composition of these gases and the study of the generation properties of the Lower and Middle Devonian rocks of the studied region are necessary.

Abstract

The southern part of the Dobrogea Foredeep is located in the southwestern regions of Ukraine within the Odesa region. Here, on the territory of the uplifted Bilolissya block, the East Sarata, Zhovtyjar, Saryjar, Zarichna oil accumulations are located in the chemogenic-carbonate layer of the Middle and Upper Devonian. The deposits are confined to limestones and dolomites with secondary fractured-cavernous-porous reservoirs. They lie at depths of 2500–3200 m. During the test of two dozen wells, the filtrate of the drilling fluid with a small amount of oil was received with the estimated flow rates of several tons per day. The rise of the oil level in the wells was quickly stopped, the hydrodynamic connection of the wells with the productive formations was lost. The use of today’s known methods of intensification of the flow of hydrocarbon fluids did not lead to positive results. According to the research of microphotographs of reservoir rocks, it is proved that the largest voids of reservoir rocks are filled with immobile bitumen, while the smaller cavities contain mobile oil. Immobile bitumen fills main channels and blocks communication between rock cavities. This is the main reason for the absence of industrial inflows of oil to the wells. Another important reason is the low filtering properties of the collectors. Most of them have a permeability of less than 0.01∙μD. Other reasons for the failure of the industrial development of oil deposits are the high dynamic viscosity of oil due to the high content of asphaltenes, silicagel resins, paraffins, the low energy potential of oil deposits due to their degassing during the long geological time, as well as the lack of hydrodynamic connection of oil deposits with natural water pressure systems. We assume that the Middle and Upper Devonian oil fields of the Western Fore-Black Sea area are most likely mainly bituminous. Given the significant depths of the deposits, their industrial development is technically impossible today. Therefore, it is impractical to plan further scientific research on the mentioned complex. Instead, research should be reoriented to the Silurian terrigenous-carbonate complex and the Lower Devonian terrigenous complex, which are hydrodynamically more closed and in which non-degassed hydrocarbon accumulations can be preserved.

Abstract

In 1957, L. G. Tkachuk and D. V. Gurzhiy have singled out the Upper Paleozoic Kuzian suite in the north-western part of the Marmarosh crystalline massif at the Rachiv area. It consists of phyllites, limestones, quartzites and dolomites. The suite is widely distributed in the Dilovets subcover of the Marmarosh nappe at the Rakhiv and Chyvchynian areas. There are two alternative points of view upon the age of the Kuzian suite. Some geologists attribute it to Paleozoic time (Upper Devonian-Lower Carboniferous), the others attribute its lower part to the Upper Paleozoic, and the upper one: to Triassic. One can notice the existence of the different estimation of the lithological composition and different estimation of the lithological composition and the volume of the Kuzian suite.Thus, in 1970 A. K. Boiko has devided it into Muntselulska (Lower) phyllite-quartzite one of Paleozoic age and Upper (Triassic) phyllite-carbonate one for which he saved the name Kuzian suite. The important is that a stratigraphic interruption was fixed between the above-mentioned units. The phyllite-carbonate Kuzian suite is dated on the basis of transgressive occurrence of the middle Triassic dolomites on it, discovery of the post-Paleozoic mosses in its lower part at the Soimul Mountain, and in the upper one: the complex of spores and pollen of Mesozoic age. Geologists, that do not recognize the idea of belonging of the part of suite to Mesozoic, indicate the next contradiction. If we accept the Mesozoic age of the Kuzian suite, so we must affirm that carbonate series of Middle Triassic-Jurassic were deposited on the massif at the same time, and 5–8 km southerly, the regional metamorphism of the Kuzian suite occurred within that zone (by the way, according to some facts at an interval of 148–178 and 175–181 mln years, and according to another information: at an interval of 196–221 mln years. This remark is not correct because the age of the Kuzian suite is Lower Triassic (251.9–247.2 mln years), but metamorphism occurred much later. In those sections where the Kuzian suite lies on the Muntselulska one, basal conglomerates consisting of pebbles and quartzitic fragments of underling suite are present in its bottom. Rocks of the Muntselulska and Kuzian suite are similar by their metamorphism intensity. For the Mesozoic Kuzian suite the manifestations of the main magmatism are characteristic, unlike the Upper Paleozoic acids. The facts testify to that the Mesozoic Kusian suite is existing, but there is a certain indefinity as to its finer dividing, stratigraphic volume and correlation with deposits of Middle Triassic. To avoid confusion, it is expedient to alter the name of the Mesozoic Kuzian suite and to name it, for example, Neo-Kuzian.

Abstract

The object of research was the Ustynivka area, which is located in the north-eastern part of the Dnipro-Donets basin on the border between the northern board and axial part of the region.

The geological structure of the area is illuminated from positions of gravitational tectogenesis. Two echelons of brachianticlinal uplifts, genetically related to the Krasnoritsk and Muratove-Tuba discharges, have been identified in the Carboniferous deposits. They were formed in nonconsolidated strata under conditions of stretching and rapid lowering of the Dnipro-Donets graben. Seismic surveys have revealed seven anticlines. Their feature is the orientation of structures along arcuate tectonic faults, asymmetry and displacement of anticlines with a depth to the southwest. According to the geomorphological features of the river valley of the Siverskyi Donets, a new uplift is predicted in the lowered block of the Tuba fault.

In the Voronove anticline, three gas deposits have been established in the Bashkirian stratum. Nearby are Borivske, Muratove, Yevgeniivka, Krasnopopivka and other gas-condensate fields. Therefore, the gravigenic structures of the Ustynivka area are promising for the discovery of new deposits. Promising horizons of the Bashkirian stratum are at shallow depths: from 2 to 2.5 km. Our estimated gas reserves and resources of the Ustynivka area are 262 and 2100 million m3, respectively.

Recommendations are given to clarify the form of gravigenic tectonic faults and related anticlines. The tasks for detailed seismic surveys and drilling are defined. The location of exploration and prospecting boreholes is proposed. Considering the displacement of the vaults of gravigenic structures with depth, to open the productive stratum in the apical parts of the uplifts, we recommend drilling inclined boreholes in the southwestern direction. Tasks for industrial development of deposits of Voronove structure are defined.

Abstract

In the article, based on own field observations, the deformation structures into the thrust zone of the Zelemianka Skyba (=thrust-sheet) onto the Parashka Skyba (the Ukrainian Carpathian Skyba Nappe) are described. They are exposed in the Hrebeniv quarry located in the Opir River basin (Lviv Region, Skole district). The tectonically disintegrated Stryi Formation (Upper-Cretaceous–Paleocene flysch) characterized by the rigid sandstone blocks (formed mainly as a result of boudinage) placed in a ductile clay matrix is represented in the Hrebeniv quarry. This formation is proposed to be classified as a “broken formation”, which is strongly tectonized, but retain their lithological and stratigraphic identity. It is a transitional element between the weakly deformed strata and tectonic mélange. Their characteristic features are: linearity of the distribution zone; significant monomictic composition and absence of exotic formations; the presence of an intensively tectonized matrix with clastolites (blocks) of less tectonized rocks of the same lithostratum (formation, series); the presence of newly formed hydrothermal minerals in clastolite cracks; the upper and lower contacts limiting the broken formation have a tectonic nature. An intensely tectonized matrix and a weakly tectonized rigid blocks belong to the same stratigraphic unit in a broken formation. The structural features suggest a brittle deformations in the studied rocks. Tectonic processes occurred in the completely lithified deposits. Thrust processes were accompanied by the formation of the duplexes, including antiformal stack duplexes, which are well expressed in the quarry. Duplexes are observed in different parts of the quarry, and the most representative ones are developed in its central section. Horses in the duplexes are characterized by a size of 1 to 3 meters here. They are generally subparallel, which is consistent with monoclinal bedding, however, they sometimes acquire an antiform appearance as a result of tectonic thrusting.

Abstract

The results of micropaleontological and sedimentological studies of the Paleocene sediments such as the Upper Member of the Stryi Formation and the Yamna Formation located in the Skyba Nappe in the Ukrainian Outer (Flysh) Carpathians are represented. Sedimentological features of the flysch successions (including the sedimentary succession along the Prut River in the city of Yaremche) proved that the Upper Member of the Stryi Formation is represented mainly by turbidites; the lower part of the Yamna Formation (variegated Yaremcha Horizon) is composed of red and green clay hemipelagites and turbidites, and the upper part of the Yamna Formation (Yamna sandstone) consists of deposits of high-density turbidite currents and grain flows.

The calcareous nannoplankton: NP1, NP2, NP3 and NP4 zones as well as the foraminifera: planktonic Globoconusa daubjergensis Zone (Danian Stage) and benthic Rzehakina epigona Subzone of Rzehakina fissistomata Zone, s. l. (the early Paleocene) are identified in the Upper Member of the Stryi Formation. The calcareous nannoplanktonic NP4, NP5, NP6 zones are distinguished in the Yaremcha Horizon and NP6, NP8, NP9 zones are identified in the Yamna sandstone. The agglutinated foraminifera including Rzehakina fissistomatа, Rz. epigona, Caudammina ovula, Hormosina velascoense, Glomospirella grzybowskii, Saccammina placenta, Paratrochamminoides irregularis are dominated in the Yamna Formation. The age of the Stryi Formation (Upper Member) is established as Danian–partly Zealandian, and the age of the Yamna Formation is Zealandian–Thanetian based on nannoplankton and foraminifera data.

Deep-water agglutinated foraminifera (DWAF) belonging to the genera Rhabdammina, Hyperammina, Dendrophrya, Ammodiscus, Glomospira, Hormosina, Reophax, Haplophragmoides, Recurvoides, Trochamminoides, Paratrochamminoides, Spiroplectammina, Karreriella are dominated in the background hemipelagic clay deposits and make up to 100% of the tests in the microfaunal associations, that suggests the lower bathyal-abyssal depths of the sedimentary paleobasin The channel deposits (Yamna sandstone) and interchannel sediments (Upper Member of the Stryi Formation) of the ancient deep-sea fan are identified in the Paleogene flysch.

Abstract

The practical experience of long-term operation of hydrocarbon deposits confirms the presence of geomechanical processes and their significant impact on the state of the gas-saturated massif of rocks. In fields that are being operated for a long time, the prospects for industrial hydrocarbon accumulation can be associated with secondary gas traps of non-traditional type, in particular, technogenic ones, which are formed in low-pore reservoirs. A detailed analysis of the geological conditions of the East-Novoselovskyi field was carried out. They contribute to the formation of additional gas resources (“behind-pipe reserves” category), as well as the establishment of geological-industrial indices of the perspectivity for the formation of technogenic deposits was carried out.

The purpose of the work is geological justification and finding perspective zones for the accumulation of behind-pipe reserves through the formation of technogenic deposits under the impact of a geomechanical factor, using the example of the East-Novoselovskyi oil-gas condensate field.

For the geological conditions of the East-Novoselovskiy Oil-Gas Condensate Field, producing the additional gas reserves should be expected from technogenic deposits that are located above the industrial horizons that are being developed and formed in low-porous reservoirs under the action of a geomechanical factor, as a result of their decompaction after gas extraction from an industrial reservoir as a result of its compression. In accordance with the conducted research, the most perspective section, from the standpoint of the formation of a technogenic deposit and the accumulation of behind-pipe reserves, within the East-Novoselovskyi Oil-Gas Condensate Field there is the strata identified in the area of wells No. 16, 18, 60, in the section interval at a distance of 92.4 m up from the roof of the horizon (B-3b), which is located from a depth of 2141 m to the roof of the horizon B-3a, at a depth of 2 233 m. It is worthwhile to further carry out appropriate geophysical work for conducting the technological work for the development of technogenic deposits in perspective zones behind the casing column in operated wells.

The account of the geomechanical factor opens up the perspective of producing the additional industrial gas influx at the late stages of the development of gas and gas-condensate fields, by predicting the geological conditions for the formation of the improved secondary filtration-capacitive properties favorable to form technogenic gas deposits.

Abstract

In the south-western part of the Krosno cover in the terrain of the Ukraine, that is called jednostka Szląska (Silesia Unit) in the adjoining Polish territory, two tectonic structures Tykhiy and Vetlina composed of flysh of the Cretaceous-Paleogene age, are correspondingly present. They are in the same scale and represent preserved anticlinal fold of the north-western strike. The Tykhiy and Vetlina structures were defined according to results of drilling. In consequence of executed drilling works the commercial gas presence of both structures was determined. Maximum gas discharges from the deposits of Oligocene at both structures are estimated to be approximately 60th m3/day. The production reserves of the Vetlina structure are estimated at 73 million m3 of gas. The deposit is not being developed due to localization in the area within the Beskydy National Park. The authors don’t recommend to carry out exploratory drilling within the limits of the structure, in located further north-east of the Tykhiy structure the Volosianka–Pidpolozzia and Husne–Bukovets scales as the ineffective drilling because of the absence of perspective objects in their composition. There are prerequisites to suppose the presence of just one more gas-saturated fold, Liuta, further south-west of the Tykhiy structure, under the Duklya–Chornohora cover. It is located within the hydrocarbon field, favourable for the search for hydrocarbons. The potential industrial gas potential of the forecasted promising structure is evidenced by the inflows of oil and gas in the mapping wells of Liuta Square. Significant manifestations of hydrocarbons were observed in well 18-Liuta. From a depth of 40 m, and then 190 m recorded oil manifestations – oil films on the surface of the clay solution (d 20 – 0.843 g/cm3; viscosity in 0E – 1.92; S – 0.22 %, the beginning of boiling – 97 °C, up to 350 °C – 56 %). Intense gas manifestations were noted from a depth of 167 m (CH4 – 95.36 %; CO2 – 1.01 %; N2 – 3.63 %). To check this supposition, it is expedient to conduct seismic survey.

Abstract

The Pohar plot is situated in the Skole district of the Lviv Region, 30 km south-west of Skole town, between Pohar and Kryve villages. Tectonically it is located in of junction of the Skybian (Slavske Skyba) and the Krosno covers. At the end of XIX beginning of XX centuries in the region of the village the oil-extracting enterprise was existent. There deposits of Oligocen and Eocene of the Rozluch belt of the Krosno cover and Oligocene of the scale of the Slavske skyba of the Skybian cover were exploited. During two ten-years of exploitation by exploring shafts and shallow boreholes more than 3 thousand ton of oil was extracted. Prospects of the Pohar plot should be connected with sand horizons of the Holovets suite of Oligocen (Klivsky sandstones) that are characterized by satisfactory reservoir properties. They are localized in the immersed part of the Hrosivsky scale of the Krosno cover separated by the Rozluch fault (tectonically screened deposit) from its forkball part, drilled in 1973–1974 1-Pohar borehole (well bottom 1935 m), due to deflection of its hole to the south-east, didn’t expose the Klivsky sandstones and didn’t solve its task. For complete exposition of the Klivsky sandstones of the Holovets suite of Oligocene of the Hrosivsky scale it is necessary to design vertically oriented 2-Pohar borehole of 2300 m in depth. About probable commercial oil-gas saturation of the horizon of the Klivsky sandstones testifies not only to the existence of the oil-extracting enterprise in the past, but the intensive surface oil shows in the stretched area that is controlled by the Rozluch fault. Moreover, taking the prospect of the zone of junction of the given covers in consideration, the seismic survey should be conducted at the Pohar area for the estimation of the geological structure of the deeper horizons and parametric borehole of 4000–5000 m in depth should be designed.
