Here we present the results of the first paleoseismic study of the Kura fold‐thrust belt in Azerbaijan based on field mapping, fault trenching, and Quaternary dating. Convergence at rates of ∼10 mm/yr between the Arabian and Eurasian Plates is largely accommodated by the Kura fold‐thrust belt which stretches between central Azerbaijan and Georgia a...

Quaternary convergence at rates of ~10 mm/yr between the Arabian and Eurasian plates is largely accommodated by the Kura fold-thrust belt at the longitude of the Greater Caucasus Mountains in Azerbaijan and eastern Georgia. Here we present the results of the first paleoseismic study of the Kura fold-thrust belt in Azerbaijan. A single paleoseismic...

Although the theories researchers use to describe the structural properties of Earth’s interior have now persisted to decades, the assumptions they make are far from realistic. Through their research, Dr Hatam Guliyev and Dr Rashid Javanshir, both of the National Academy of Sciences in Azerbaijan, have integrated concepts from both mechanics and Ea...

We studied the isotropic ball using data of Preliminary Reference Earth Model (PREM). It's shown that such a ball should be either destructed or gone into a more stable equilibrium state with uneven distributed deformation under thermobaric condition of the inner core. Body elastic waves with real velocities cannot propagate in it. This manuscript...

A matrix approach has been used for accelerated solving problem of determining the quantitative relation between the components and porosity of the rock. From geophysical log data , in the Tengiz field (Precaspian) and Fakhdy (Syria) examples, we have obtained the graphical representation of the mineral composition and porosity of rocks in a sequen...

Data on hydrocarbon group composition of oils—as a whole and in various fractions—are of great importance for understanding the process of the transformation of petroleum and constructing a genetic classification of oils. This chapter explains models of hydrocarbon group composition and main properties of oils, relationship between composition and...

It is normal practice to formulate the tasks for the choice of the best decision such that the comparison is based on a unique preferable criterion (penetration, bit run, overall rate, cost per meter). At that, the best decision is thought to be the one providing the maximum rate (or minimum cost per meter). This approach, however, seems unsuitable...

Axiomatic principles for simulation of the process of sediment compaction were formulated. On this basis, a multiplicative model of compaction of sedimentary rocks was prepared, which is a principal part of models representing changes in rock properties under the influence of thermobaric, structural-lithological and geotectonic factors. On the basi...

M u d volcanism is pne of the most interesting nature phenomenon, which occurs in many coun- tries of the world. However, Azerbaijan is unrivalled in number of volcanoes, variety of forms, freguency of eruptions.Mud volcanoes differing from magmatic volcanoes on activity area astonish by their beauty, but their direct connection with oil and gas sy...

Buckling of a packet of geological strata, for example, because of folding, may redistribute the stress over certain internal areas shorter than the radius of curvature of the buckled region. İn this situation, the resulting internal stress may shear the packet horizontally; along stratal surfaces, even in the absence of any (other) externally appl...

The present paper highlights the problems related to the abnormally-high formation pressures (AHFP) in the oil and gas fields of Azerbaijan and the South Caspian Basin. The authors discuss the origin of abnormally-high formation pressure, diagenetic-catagenetic montmorillonite-illite transformation and hydrochemical factors. On the basis of new dat...

For the first time, we have discovered processes in deeply (4.5-6.0 km) and super-deeply buried (>6 km) complexes of deposits in Eastern Azerbaydzhan facilitating the preservation of favorable fluid barriers and reservoirs at the depths investigated (down to 10 km); this is yet another indication of the great promise that such complexes hold for fi...

Искривления в слоистых структурах Земли, возникающие, например, в процессе складкообразования, могут приводить к такому перераспределению напряжений в некоторых площадках, чьи размеры меньше геометрических размеров(параметров) искривлений, в результате которого появляются внутренние напряжения, достаточные для начала процесса разрушения расслаивани...

В теориях о развитии Земли и в геотектонике [1,2,3], наряду с другими главными структурными элементами, важное место занимают глубинные разломы. В настоящее время сформировалось прочное мнение о том, что эти разломы, подчиняясь определенным закономерностям, в основном расположилось на радиальных (вертикальных относительно наблюдателя с дневной пове...

A three-dimensional nonclassic linearized mathematical-geomechanical mo-del of lithosphere structure de-velopment created by the authors earlier shows, that in various conditions such structural elements as folds and cracks can be formed in local, regional and generally planetary scales. The formations isolated and global structural elements commun...

Formation of diapers is an interesting natural phenomenon. Numerous diapers, diapiric ridges and complexes have been described by now. They are typical to orogenic zones and deep synclines of platforms. According to morphologic properties, one can mainly, distinguish between clayey and saline diaperism. These varieties of diapers are characterized...

We have already described (3) a folding mechanism which assumes that crustal blocks lose equilibrium when force is applied (3). From this model one can determine, given the block geometries and mechanical properties ot the rocks making up a given structure, the force that will produce folding and the depth at which the block undergoing folding is l...

Складчатость структуры земной коры - давно установленный факт. Вместе с тем, проблема складкообразования продолжает оставаться в центре внимания исследователей, служит объектом научных дискуссий.

Предлагается модель возможного механизма формирования горизонтальных сжимающих сил за счет внутренних факторов осадочного комплекса, что позволяет с новых позиций подойти к проблеме складкообразования и связанных с ним процессов. При этом особая роль принадлежит процессам формирования и развития аномальных давлений поровой жидкости. (АВПД).

In this paper we present a mathematical model of a general mechanism of folding. We emphasize that in this formulation the nature of the forces producing the folding is immaterial. The rather general character of the model enables us to give these forces and other parameters specific geometric, mechanical, or mining geological interpretations of va...

Проблема формирования складчатости горных пород до сих пор сохраняет свое принципиальное значение.В последнее время наблюдается даже тенденция возрастания интереса к дальнейшим поискам и обоснованию адекватного механизма складкообразования. В настоящей работе излагается математическая модель одного общего механизма складкообразования.

Проблема формирования складчатости горных пород до сих пор сохраняет свое принципиальное значение. В последнее время наблюдается даже тенденция возрастания интереса к дальнейшим поискам и обоснованию адекватного механизма складкообразования. Существующие представления сводятся к тому, что в природе действуют два основных фактора складкообразования:...

The South Caspian basin contains both sands and shales that have pore-fluid pressures substantially in excess of hydrostatic fluid pressure. Pore-pressure data from the South Caspian basin demonstrate that large dif- ferences in excess hydraulic head exist between sand and shale. The data indicate that sands are acting as drains for overlying and u...

Experimental investigations of Pliocene clays in the Baku Archipelago have noted that the persistence of montmorillonite content to 6200 m is connected with predominance of the process of secondary montmorillonite formation from illite over the process of primary montmorillonite destruction. Based on the mechanism of interrelation and reciprocal in...

The Baku Archipelago, in the Southern Caspian Basin of the USSR, yields hydrocarbons from wells that have reached a maximum depth of 6.5 km. The presence of commercially producible hydrocarbons, particularly gas, is forecast to be present at depths as great as 9 km. Extrapolation of trends observed down to depths of 6.5 km suggests that suitable re...

The analysis of the exploitation of the oil and gas fields with abnormally high formation pressures (AHFP) revealed the possibility of the pore water influx from the overlying, undercompacted, overpressured shales into the productive zones, situated at the lower levels. A study of a well with abnormally high formation pressure in South Louisiana sh...

Relationship of porosity (φ) to depth of burial (D, in m), geologic age (A, in millions of years), and lithology (ratio of thickness of shales/total thickness of terrigenous deposits = R) has been developed by the writers, which gives satisfactory results: where φ0 = initial porosity of the argillaceous sediment. A nomogram has been prepared for an...
