A brief overview of the Conference

A brief overview of the Conference

Results of work of territorial branch of the Central commission on Republic of Tatarstan oil fields development in 2008 are given. The problems, which need to be solved for the further perfection of development, increase of production level, final oil recovery factor, are designated.

Current well-test technologies and mainstream of its progress are presented. General evolution concept of well-testing in Russia is substantiated. It is the same for all modern production monitoring control system – priority change. It is noted  main aspect of the modern methodical well-testing is the whole reservoir study, data gathering for numerical model, and as result production optimisation and increase in recovery. One more important aspect of well-test evolution is the conversion of singe well-testing to massive bottom-hole measurements by stationary remote gages in all wells in the field.

Rosneft Oil Company resent experience in hydrofracturing of low-productivity horizontal wells and brief survey of applied technologies are presented. Specificity of horizontal well fracturing and differences from vertical wells case are discussed. Conventional fracturing, assuming creation of longitudinal fractures is compared with multiple-point stimulation of horizontal wells. Horizontal well fracturing field cases are presented, treatment details and stimulation efficiency are described.

Results of drilling of wells and sideholes with the horizontal termination for oil reserves development from bobrikovsky object of operation are considered. Ecological compatibility and economic efficiency of horizontal technology - drilling and operation of wells of complex architecture - is noted.

In this paper method of reservoir pressure mapping based on well test and production data is presented. Use of well production data allows to estimate reservoir pressure at the entire field, particularly in areas not covered by well testing.

Two technological variants of gas-water bed stimulation are developed. The scheme of nonuniform bed stimulation with use of the compressor is given. The new generation three-phase filtration research device is created. The physical  model of process of gas-water displacement of oil on samples of a core is developed.Presented method was successfully applied to several West Siberian oil fields

Economic criteria of the fields development, and also of hydrocarbons resources control system are considered. The group of data, which are necessary to consider at an estimation of recoverable hydrocarbons volumes, is presented. The example of the technical and economic forecast of an oil recovery from one well depending on the oil price is given.

The authors give answers and explanations to the opponents’ criticism of the new concept of effective pore space in theory and practice of oil and gas fields development and development planning.

The method of study of physical and chemical properties of well productions (oil, gas, water, oil acids and so on) was used to analyze the processes , taking place inside well and formations. In order to study CO2 H2S gases quantity percentage increase group and gomologic compositions of well productionoils  , formation water and oil acids were carried out using the method of mass- spectrometry.

Special compositions and technologies for elimination of lost circulation in wells at Republic Saha (Yakutia) fields and license areas are developed. Results of research and experimental-field works are given. The technology of solar-cement- bentonitic mixtures delivery in the disastrous lost circulation zone is considered.

The software product, allowing both to optimize the drilling fluid composition at a stage of its designing and preparation

Results of the field trial of the emulsion breaker Decleave™ S-1251 at the plant of Severnoeneftegaz OJSC TNK-BP are presented. This object is characterized by low oil mobility, high oil chilling temperature (21-25 °C) and high content ofasphaltene, resin and paraffin components in oil

The technique of heat conductivity determination is given. The scheme of laboratory setup for performance of laboratory researches is presented. The received results are considered. It is drawn a conclusion on the capability of application of the offered technique of calculation of large soil massifs heat conductivity

Limitations and inefficiencies of traditional datacenter support systems are described. Also problems in implementation  of datacenters in remote locations are given. The article describes the advantages of containerized datacenters as one of the tools to achieve greater levels of economic efficiency and flexibility to support changing and growing IT infrastructure of modern oil and gas company

The brief analysis of a current status of an environment in the territory of Tatneft OAO activity is carried out. A species diversity of flora and fauna representatives is estimated. Efforts for the environmental conditions determination are performed.  The parameter of stability of region ecosystems development is computed.

The principal causes of failure of oil pipelines and field pipelines are considered. Given are the applied for liquidation of outflows sorbents, capable not only well to absorb oil and mineral oil, but also to biodecompose them. Sorbents on the basis of peat sphagnous moss are considered. Efficiency of their application for restoration of polluted soils is noted.
