The work is focused on identification changes in formation oil viscosity as part of the pilot studies on fluid transition between the single-phase state and two-phase liquid state, and obtaining data on saturation pressure (Psat.) when addition of Karpatol into crude oil.

Dependence of Jetibay oil field bioinfestation from external factors were analyzed. The main source of bioinfestation is a long injection process of unsterilized surface water. There is a significant temperature dependence on the activity of SRB (Sulphate Reducing Bacteria) and the amount of hydrogen sulfide generated. In addition, a gradual increase in well watering and modification of associated water cation-anionic composition also increases the corrosive condition in the fields.

Although waterflooding is one of the principal and the most effective methods of oil-and-gas field development and in favourable physiogeological conditions enables increase of an oil recovery factor up to 0.7, its application to fields with hard-torecover reserves is inefficient. Productive formation heterogeneity by permeability and oil and injected water viscosity correlation have great impact on formation sweep by waterflooding. New flow diverting technology (FDT) based on regulation of gelled water margin viscosity has been suggested in order to increase sweep of a less permeable part of a productive formation by impact. In the article, results of laboratory researches on a displacement process of residuals after oil flooding by gelled water margin injection are given. The analysis on pilot introduction of the suggested technology in the "Uzen" field has been presented.

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 theoimasha 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 theOimasha field and hydrocarbon reservoir exploration in basement rocks in the contiguous areas of Southern-Mangyslak. New data concerning the geological description of the Oimashafield (one of the most interesting fields of Kazakhstan) concerning the calculation of hydrocarbon resource are presented.

This article deals with the complex block structure of pay thickness in "Arman" oil-and-gas field. The new data on the field were analyzed by the author during active participation in the work on recalculation of initial reserves of oil and gas in Arman field. The deposition of Jurassic systems occurs on an erosional surface of middle Triassic and are presented with non-segmented Bajocian and Bathonian stages of Middle Jurassic. Lithologically -they consist of sandy and clay rocks. Sandstones are grey, dark-grey, polymictic. Clays are dark-grey, micaceous, and silty, with inclusions of plant residues. The main part of the field pay thickness is connected with these depositions. The thickness of Jurassic depositions unit is 490-520 m.

The Zhetybayskaya group consists of 13 satellite fields. They are "Asar", "Southern Zhetybay", "Eastern Zhetybay", "Burmasha", "Bekturly", "Ayrantakyr", "Pridorozhnoye", "Alatyube", "Atambay-Sartyube", "Aiagar", "Northern Karagiye", "Northern Akkar" and "Oymasha". The fields connected with Triassic depositions are the following: "Pridorozhnoye", "Alatyube", "Atambay- Sartyube", "Aiagar", "Northern Karagiye" and "Northern Akkar". The most frequently met problems in these fields are: non-fulfillment of measures on methods of formation stimulation and bottom-hole zone treatment (injection agent, pumping volumes, time of performance); reduction of projected oil recovery factor; ombination of two and more development facilities; changes to procedures for commissioning and decommissioning wells.

At present it is considered to be determined that oils of many Western Kazakhstan fields with a high content of high-molecular compounds have complex rheological parameters that are at a certain temperature interval characterized with a wide range of non-Newtonian properties. To one of the most characteristic fields of Western Kazakhstan with complex rheological properties of oils can be referred Uzen field aggravated with unfavorable properties of producing horizons reservoirs.

One of the most general forms of environment control is an ecological monitoring i.e. monitoring of change of parameters of environment processes and phenomena. Within the framework of CIS there is an Interstate ecological council that designed the programs of work including: the design of interstate scientific and technical program of generation and development of ecological monitoring in the territory of member states of CIS; the forming of interstate ecological information system. The main direction of problem solving is the generation of automated systems of monitoring and management of environmental quality based on modern scientific achievements including information technology [1].

The paper proposes introduction of difficult destructible oil processing plant (PDDO) and plants of complex lake oil treatment (CLOT) on the example of fields "Uzen" and "Karamandybas" JSC " Ozenmunaygaz". Plants of PDDO and CLOT put into operation are an effective solution for cleanup of polluted area and processing of raw materials accumulated in the lake oil and provide easy maintenance of these facilities due to technological equipment already available to oil companies. We propose change of technological workflow for preparation of products with the introduction of additional hardware in order to improve the product processing technology's efficiency on PDDO unit. Implementation of the proposed technology will reduce the corrosion of tanks at PDDO's object, thus increasing their service life, and will improve the quality of prepared products.

During 50-90 years of the last century a large complex geological prospecting operation was conducted in Southern Mangyshlak. This article provides a brief overview of the results of the interpretation of geological and geophysical data and exploration drilling to evaluate the hydrocarbon potential of the pre-jurassic and jurassic-cretaceous complexes of the Zhazgurlinsk depression as well as providing a set of further exploration tasks.
