As a result of combined analysis of seismic surveys conducted in Gurgan-deniz and neighboring areas and logging data as well, the geological structure of the studied area was specified, various seismic attributes (both as by seismic cubes and by separate seismic surfaces) were calculated. To have a clear insight about the lithofacies variability of the studied area, corresponding 3D models have been developed. With the purpose of restoring the sedimentation conditions, a facies analysis of the area based on the visual study of the length and configuration of seismic reflections, as well as seismic amplitudes has been carried out, the changes of the power of separate intervals in which we are interested have been studied and the logging of the facies conducted. To define the connection between the dynamic parameters of seismic records and geological properties of the area in the promising intervals, several attributes (Sweetness, RMS, Instantaneous Frequency, Variance etc.) have been calculated and analyzed. The calculation have been conducted in a large diapason for all productive horizons (marked as potential reservoir). Sharp changes in the composition of rocks in the studied area are associated with a periodic transgression and regression, as well as with the fluviation. Three types of geological phenomena may occur during specific periods of cycle turns of rising and lowering of sea level: progradation and regression (recession of the sea), retrogradation or transgression (sea movement towards shore) and aggradation (comparatively stable state of sea level). In the view of sharp variation of lithologic composition of the sediments, predominantly in the bottom of Productive Series (PT), we can conclude that highlighted facies are characteristic for specific parts of the studied area. When highlighting the facies, the direction of sedimentation material brought by the rivers and source of nourishment has been revealed. According to the results obtained, we suppose that almost each lithofacies type has its own distribution area. Therefore, the fluviation plays a significant role in the distribution of the facies in the studied area of the Caspian basin, as well as in the accumulation of hydrocarbons. Complex research surveys carried out enabled to mark specific perspective oil-gas bearing objects in Gurgan-deniz and neighboring areas.

One of the recent achievements in the field of the systems of operated rotary wing providing fast increase of curving angle is a hybrid system combining the characteristics of the systems of control and deflection of axe. There are several theoretic methods of calculation of curving intensity іα. The first of them is a method of using the depth by the vertical h and by horizontal s. In this method curving radius R is considered permanent (i.e. it changes along the circle arch). The second method of calculation of curving intensity is a three-pointed technique, which can be applied for the drilling with a curved casing and with the systems of “Point the bit” as they are operated with similar mechanisms.

Recently, the development and implementation of efficient technologies and technical tools to stabilize and increase the production in new oil and gas, as well as in mature fields are one of the urgent tasks. Therefore, new advanced methods of increasing oil production in the fields are necessary. The issue of struggling with the complications may be solved due to the development and wide scale employment of progressive techniques in the sphere of intensification of production in existing fields. Thus, considering the fact that the great majority of Absheron oil fields are in the last stage of development, as time goes by the changes in the reservoir lead to the formation of some complications in the operation wells, the solution of which remain an urgent challenge.

The paper presents the methods of estimation of quality and filtration characteristics of the reservoirs – quality index of layers (QIL) and indicator of flow zone (IFZ). With the purpose of the specification of QIL and IFZ parameters through the well sections, the dependences using core sample analysis and the parameters obtained with the methods of well logging have been developed. Three-dimensional petrophysical models and more detailed cross-sectional profiles by QIL and IFZ parameters allowing highlighting the areas with better reservoir properties of the studied field have been developed using estimated parameters..

A long way of development of cementing technology providing the advancement of backfill materials, the methods of preparation, chemical treatment and transportation of plugging material into the borehole annulus of the well did not solve all the problems of the quality isolation of formations. There are neither justified physical criteria nor accurate methods of estimation of supporting quality, as it is quite troublesome to set well conditions while conducting experimental works towards specifying the large number of the factors simultaneously affecting the longevity of well support. In this regard, there is no generally accepted method of testing backfill materials and the issue of necessary sustainability of stone from various bakfill materials designed for cementing of columns and setting cement bridges is not solved as well. Leading drilling service companies (Schlumberger, Halliburton etc.) of the world do not use special cement types and instead, prepare their own mixture for each cementing process on the basis of cement of selected for these oil-gas fields. As a result of mixing various types of weighting agents and other additives with base cement, a backfill system necessary for specified well is obtained. These systems are produced on specially equipped facilities in the world. The researches carried out justify that it is possible to obtain high quality simplified and weighted cement slurries on the basis of domestic raw materials with state-of-the-art technologies and equipment.

The paper reviews the necessity of using modern methods of diagnostics based on the up-to-date technologies for revealing probable damages in the pipelines and some equipment. Considering external and internal impact in the pipelines, it is necessary to conduct regular diagnostical tests. The main reason for the damages of pipelines and equipment is the formation of tension concentration as a result of the effect of some loads on these devices. Due to this, the reliability of gas pipelines in the operation is defined by a criteria of strain-stress state occured on these lines. The methods of technical diagnostics based on the up-to-date technologies should be implemented for revealing probable damages within the pipelines and equipment as well. Smart-of-the-art software technologies for performing calculations have been used in the research surveys. Within the report period, the pipeline has been tested with the method of magnetic memory (MMM) and currently is used as the most effective option.

The territory of Azerbaijan is favorable by hydrogeothermic conditions and is divided into several regions. Khachmaz-Khudat is the most perspective among these regions for alternative and renewable energy sources. Thermal waters with 86 оС temperature on the Earth surface are the source of high energy. The consumption of these waters obtained from Upper Cretaceous complex reaches up to 6000 m3/day, the mineralization of the water, which have generally chloride-natrium composition is not so high (64 g/l). According to the temporary and permanent parameters of condition, the use of the water from the well No 116 in Khudat region is possible for heating of surrounding settlements. Moreover, thermal waters obtained from the well No 112 have high temperature. These waters with 82 оС temparture at the wellhead, can fully meet the demand of surrounding canning plant. By the hydrogeothermic conditions thermo-mineral waters taken from the wells No 5, 6, 7, 9, 10, 12 and 113 on the onshore profile of Khachmaz-Khudat region are considered favorable. These waters the temperature of which exceeds 50 оС in Nabran region are efficient to use in medical-resort complexes.

The paper offers a classification of pipelines for the characteristics of efficiency of operation of existing system of pipelines, as well as for prediction of further fails. Oil and oil-gas subsea pipelines, which are in the balance of analyzed OGPD, have been divided into three conditional groups by construction years. As a result of such a conditional distribution, an attention is paid to the necessity of appropriate estimation of operation resource, quality standard and technical condition of the pipelines in the first group. Although the classification partly characterizes the technical condition of the pipelines, it is quite a practical diagnostic tool in the struggle against the decrease of reliability and quality of the subsea pipelines operated in recent 20-30 years in the complicated offshore conditions with increasing probability of failures and risks in transportation system. Offered classification covers all subsea pipelines used in the development of offshore fields, as well as can serve for improvement of their operation reliability.

The paper reviews the task of definition of hydraulic load in the border of load wave generated via hydrodynamic stimulator. It was specified that high frequency hydrodynamic effect is carried out with a device of special design – cavitator, which is lowered into the well on the drilling tubes and there are special inserts on its body stimulating periodically stall cavitation and therefore, hydraulic loads in the walls of borehole and favorable conditions for cleaning bottomhole zone due to the improvement of hydraulic conductivity of the rocks forming this zone are created as well.
