[en] Full text : In this article it is described Baku and its surrounding areas, where the main tectonics are the Caucasus, strike-slip faults and reverse faults. The Caucasus is a part of the Alpine-Himalayan folding belt and situated between the Arabian and Eurasian plates. The main faults in this region are the Pembak-Sevan fault, the Garni fault and the Talesh fault. The Pembak-Sevan fault and the Garni fault are characterized by right-leteral strike slip faults. The Talesh fault is characterized by reverse fault and the Talesh Mountains have been thrust over the south Caspian depression. Some earthquake catalogues for Baku and surrounding region had been prepared from different sources. The qreat earthquakes had been occured in the Caucasus, the Caspian sea and the Tales fault and around Baku.
[en] Full text : Mud diapirism plays a special role in the geology and petroleum system of the south Caspian basin. Hundreads of mud intrusions penetrate the thick Plio-Pleistocene section. This article talks in detail about aspects of the influence of mud diapirs and their related with mud volcanoes on the generation and trapping of hydrocarbons. Some of these aspects are : 1) The influence on the sedimentation; 2) Structural impact; 3) Stress and strain in the surrounded formations; 4) Thermal effect; 5) Pressure effect. All these aspects of the diapiric and mud-volcanic activity should be kept in mind during the volumetric calculations and play evaluation.
[en] Full text: The Caspian Sea is the world largest lake that is also considered as a totally enclosed sea.Morphologically it is divided into the northern, central and southern part.The thickness of terrigenous sediments in the southern Caspian sea is up to 20 km.This study evaluates significance of the Pliocene sediment mounds and clinoforms were found adjacent to this time line in the deep part of the basin.These mounds show features similar to deep sea fans, characterized by subparallel and hummocky reflection patterns.The estimated average thickness and width of the four studied mounds are 456 m and 14.2 km, respectively, suitable to form stratigraphic traps.
[en] Full text : We calculate volume of gas reserves by using two methods: probability and possibility methods. To do this we use equation. Single valued estimates are not appropriate because of inherent (and large) uncertainties associated with these estimates. Application of monte Carlo method, which is a method of statistical trials, and the method of fuzzy arithmetic allow us to obtain range of values estimates of free gas reserves instead of single valued average estimates. Tp perform Monte Carlo analysis, probability distributions of input variables must be assumed. For all variables in equation we assumed normal distrubutions
[en] Full text : This article tells about sedimentation occurring more intensively in the south-west Gobustan, where a long subsidence of the basins floor occurred. As it is known in the Shamakhy-Gobustan region the stratigraphic interval is the Maycopian and younger deposits. In the Maycopian deposits the most thick sands and sandstones with good reservoir properties occur in the sections of different local regions. To determine regional reguliarities of the change of reservoir parameters in the studied region all gathered data were loaded into computer. Average values of every parameter for certain areas and stratigraphic complexes were calculated.
[en] Full text: Sustainable growth in the energy industry is rapidly expanding beyond the conceptual stage. Policies addressing the three principles of Sustainable Development are being established and strategies to execute these policies are being developed and implemented in the field. Conoco is developing a strong corporate culture around sustainable growth; and, pipeline systems play a vital role in delivering the triple bottom line results for our stake holders. This paper will highlight some of the key focal points by Conoco Inc., in each phase of pipeline project development, execution, and operation to make pipeline projects a contributor to Conoco's sustainable growth success, and shares some lessons learned
[en] Full text : This article provides with new data, which are of great importance for the understanding of hydrocarbon system peculiarities if the south Caspian basin. There was determined non-coincidence and sometimes back correlation in the folded structure of complexes of different ages and also different orientation of axes of the folds and directions of faults in different tectonic zones. In the sedimentary cover of the south Caspian basin there were identified specific structures associated with generation and migration of hydrocarbons. Large-scale migration of hydrocarbons occurs instantly from time to time. It was determined that most earthquakes occurs in the south Caspian basin in the sedimentary cover at depth from 10 to 20 km and paragenesis of mud volcanos eruptions was determined too. There exist an opinion that the improved technology of hydrocarbon exploration will increase the efficiency of exploration works in a complex basin like the south Caspian one.
[en] Full text : This paper gives analysis of Guneshli oil field development in time and justifies the change of development strategy of any object with getting more detailed data on reservoir structure, including results of 3D modeling. It is obvious that development efficiency of an oil and gas field straightly depends upon the level of research done to reservoir of any target structure. Of great importance here is data on every parameter characteristic to reservoir. It can be parameters determining physical properties of research and genetically connected with conditions of deposit sedimentation in certain geological time or can be parameters conditioned by general development of the sedimentation basin and specific properties of formation of the structure with which oil field is connected.
[en] Full text: Early theoretical studies concerning AVO analysis indicate that major rocks properties as S-wave velocity and Poisson's ratio can be derived, provided that incident angle exceeds zero, while reflection wave analysis. In this regard, there ara rigid theoretical calculations as linear function reflection signal amplitude and incident angle. This effect is too weak, and therefore there are some difficulties using them in exploration. The major requirement embraces such a high reflection angle as possible. Advanced digital acquisition technologies made it possible to apply said theoretically postulated relations and overcome those difficulties.
[en] Full text : This article tells that the oil bearing capacity of the south Caspian is connected with powerful sedimentary deposits. This stratum named - productive series, are characterized significant facilities by variability : the heterogeneity in display of parameters is observed both on regional scale and on the areas of separate structural raisings. Thus the basic characteristics of variability productive series are the interwoven in its cut-section of alternating sandy and clay layers. However on bedding character of cut-sections of adjournment of various deposits strongly differ, therefore splitting productive series on stratigraphical unit everywhere there are difficulties. In such conditions the technological decision of management of production hydrocarbons is obviously possible. The statistical method of differentiation of geological objects on a complex of attributes allows, objectively for solve the problem on an opportunity of association of layers in general object for development. Later it was offered a new method on a complex of properties on an example Neft Dashlari Oil field. The given method can be used with reference to other deposits at various stages of development.
