The development of seismic technologies has enabled a more detailed study of the structural definition of the producing formation. Because of thin-bed vertical resolution and the formation depth, the most promising geophysical method is the seismic survey MOGT-3D as means for detailed study of the geological structures of the reservoir. Carrying-out the MOGT-3D seismic survey using modern technical methods and practices as well as use of dynamic, paleo-geomorphological and paleotectonic analysis in the process of interpretation of the seismic data permits, with high degree of confidence, not only an interpretation of the geological structure but also to conduct zoning of the reservoir by sedimentological environment, to enable forecasts of facies extent and reservoir properties in the geological section. Seismic survey 3D works have not yet been carried out on the Atambai-Sartyube field. A brief description of the field is given before demonstrating the necessity for the execution of the planned programme.

This article concerns the Oimasha field basement granitoids oil and gas content, problems of the formation, exploration and appraisal of unconventional types of reservoirs and dedicated multiconstructed facilities. Comparison and analysis of actual data from the Oimasha field, literary sources of analogous fields from different parts of the world allowed the author to formulate plans for further exploration of the Oimasha field and to carry out evaluation work on the Southern Mangyslak. The article consists of three parts. The first one is dedicated to a brief geological description of the field, the second to the analysis of basement (granitoids) oil and gas content of different regions of the world and the third to perspectives of supplementary exploration of granitic intrusion of the Oimasha field and hydrocarbon reservoir exploration in basement rocks in the contiguous areas of Southern-Mangyslak. New data concerning the geological description of the Oimasha field (one of the most interesting fields of Kazakhstan) concerning the calculation of hydrocarbon resource are presented.

We have investigated the effect of CrB2 additive on the structural formation of diamond composite with WC-6Co hardmetal matrix obtained by hot pressing in the temperature range 20 - 1450 оC and pressure range 0.5 - 50 MPa. We have found that this additive prevents the formation of graphite during the reaction of diamond with hardmetal matrix and facilitates the formation of a fine-grained homogeneous structure of matrix material in the vicinity of diamond particles, with a simultaneous increase in the mechanical properties of the composite. The composite which is obtained has enabled the development of the drilling tools prototypes with wear resistance considerably exceeding that of commercially produced tools.

Evaluation of the influence of uncertainty of relative permeability functions in a "gas-oil" system on development parameters and the influence of end points has been carried out on the basis of digital filtration model of oil-gas-condensate field values of critical gas saturation and relative permeability at residual oil saturation. Methodical recommendations are given on a methodology to decrease error and suggestions for further investigations in this subject. The preparation of a field development project has a substantial set of uncertainties. Each stage of development starting from seismic survey and exploration and appraisal drilling and ending with economic calculations, contains many assumptions and simplifications. The existence of a primary gas cap on the field influences production rates, the duration of work, well drainage areas, etc. A quantitative evaluation of uncertainties and their influence upon economic factors of development is significant step during the planning phase. This work concerns the theoretical aspects and evaluation of one of the main uncertainties connected with modelling of a field with gas cap using a digital filtration model of the relative permeability function for the "gas-oil" system.

Many reservoirs employ artificial thermal (heat) methods of bed stimulation to improve the recovery process of oil. In order to understand the different problems of thermal bed stimulation many experiments were carried out and the economic efficiency of hot water injection is established in permeable beds, saturated with high-viscosity oil. There are many theoretical studies using numerical and analytical methods to solve different problems connected with thermal bed stimulation [1,2,5,6 etc.]. Here we present the development of a simple analytical method of calculation of the oil reservoir temperature field in a multi-layer system. The problem of determination of multilayer oil reservoir temperature with variable boundary conditions is considered in the article.

It is well known that increased rate of water encroachment causes intensive rock wash-out and, as a consequence, an increase of mechanical admixture content in produced output. To enhance well efficiency and increase operational reliability may require a considerable volume of repair works and geological and technical measures necessitating specialized techniques and service and personnel. This results in a reduction of maintenance and intervention periods and well operation repairs and increases influence of the human factor. In certain geological and field conditions, operating wells using ejector (jet) pumps is cost effective. Ejector (jet) pumps, thanks to their particular construction, are notable for their reliability and provide long period of well operation between maintenance.

The protective effect of amines on steel corrosion under simulated conditions of gas condensate fields are reported in this article. The impacts of inhibitor chemical structure, СH₂S, рН, temperature and hydrocarbon phase presence on the protective effect of studied compounds were investigated. It is shown that, in some cases, volatile amines are effective vapor-liquid phase inhibitor against hydrogen sulphide corrosion.

A drillable packer is used as the primary element for leak-free shutoff of a well bore during operation of oil, gas and gas-condensate wells. Its removal from a well, if necessary, is carried out by drilling it with a special milling tool. The article deals with the fabrication of equipment based on the analysis of modern methods and similar tools designs. The most effective geometrics and hard-alloyed component have been selected as a primary element of new design for the cutting edge. The modelling of loads acting on the cutting tool and the cutting operation optimisation have been realized using Autodesk Inventor software.

According to researches’ results of last 10 - 15 year, after implementation of complex measures on cleaning of sea, average indicators of oil and phenol density are abating, while in some places it doesn’t exist. Since 2000 until today, monitoring works have been conducted in 12 fields of 5 Oil-Gas Extraction Establishments. As a result of these researches, it has been discovered that makrozoobentos and its quantity has spread in the Absheron and Baku archipelagos of Caspian Sea. While working at materials collected during the period of conducted hydrobiological expedition in 2005 - 2008 in Azeri Sector of Caspian Sea, a new species of cumene crustaceas was discovered – Volgocuma caspia sp. nov. This discovered species is of cumene, Volgocuma. In Caspian Sea there are 18 species of Cumacea, distributed among 8 generations. 2 of them and 6 species are endemic for that sea. In the article there is a description of Volgocuma species and areas and stations of its revealing.

We show that a very thin (5 – 80 nm) gas phase can exist for a long time (>1 h) at the interface between a hydrophobic solid and water. We create the gas phase from CO2, which allows us to determine the chemical identity, phase state, and density via infrared spectroscopy. The average density reveals that the gas is at approximately atmospheric pressure, which explains the unexpectedly long lifetime of the gas phase under ambient conditions. The nanoscale gas phase is reproducibly created under conditions where gas solubility is varied.

Imaging of hydrophobic surfaces in water with tapping mode atomic force microscopy reveals them to be covered with soft domains, apparently nanobubbles, that are close packed and irregular in cross section, have a radius of curvature of the order of 100 nm, and a height above the substrate of 20–30 nm. Complementary force measurements show features seen in previous measurements of the long-range hydrophobic attraction, including a jump into a soft contact and a prejump repulsion. The distance of the jump is correlated with the height of the images. The morphology of the nanobubbles and the time scale for their formation suggest the origin of their stability.
