The oil and gas industry


G.I. Shmal, president of the Union of Oil and Gas Producers of Russia
The basic strategy of the state oil and gas industry must be innovative component

Key words: oil and gas complex, reserves, geological exploration, investment, innovation and modernization, industry science, cadres, the state.

The main trends and problems of development of oil and gas industry of Russia are considered. It is shown that, despite the efforts made, the actual problem is the reproduction of mineral raw material resources. It is noted that the modernization of industry is impossible without appropriate scientific support. The main lines, in which efforts of industrial enterprises, scientific organizations and the state should be concentrated, are presented. The necessity of development and urgent realization of a complex of measures is accentuated.

Reservoir oil viscosity impact on reservoir oil saturation under core sample laboratory studies

Key words: reservoir, viscosity, residual oil saturation, water oil displacement factor.

The paper provides for the results of laboratory study for reservoir oil viscosity impact on oil saturation of Bobrikovskoye horizon and Tournaisian stage reservoirs. Laboratory tests were performed according to OST 39-195-86 using complex reservoir models with sufficiently close average permeability characteristics of coeval deposits and different oil viscosity. Obtained results show that reservoir oil viscosity under studied values has insignificant effect on residual reservoir oil saturation. In this case, to achieve final water oil displacement factor and residual oil saturation different quantity of water shall be pumped through porous medium depending on value of reservoir oil viscosity.

Experience of increased cementing quality at the wells of Tatneft OAO

This article describes the results of using lightweight expanded glass granules in cement slurries used for well cementing by ОАО «Tatneft». Laboratory testing of the cement slurry confirms that Super-К aggregate is evenly distributed in the cement slurry, increases sediment stability of the cement slurry and increases the compressive strength of the cement matrix, ensures better bonding to the formation and the casing. Tatneft performed an extensive 9 well field testing program for cementing of production casing using the new Super-K lightweight cement slurry composition in 2011. The Super-K technology helps reducing well construction time due to avoiding two-stage well cementing with the use of stage collar. Adding lightweight glass aggregate with the closed internal pores to the cement slurry positively influences the quality of well cementing.

Key words: well cementing, lightweight aggregate, expanded glass micro granules, one-stage cementing, strength, Super-k.

New apparatus addresses to solve the problem of bit balling

Key words: drilling swelling formation, accretion of clay, bit balling, adhesive interaction, sticking the pipe string.

Drilling bit balling leads to a decrease in the rate of penetration and the various emergency situations. Improving of anti-adhesion properties of drilling mud during drilling swelling formation reduces the adhesion of the clay slurry to the surface of the drilling bit. A description of the apparatus, which allows to estimate the ability of drilling mud to inhibit drilling bit balling, is given.

Using the material balance and the fuzzy sets theory to solve the problems of recovery separation at simultaneous development of several reservoirs

The theoretical formulation and algorithm of solution the problem of fluid recovery separation at simultaneous development of several reservoirs together are given. As a test example the solution for the object of development, consisting of five reservoirs, is given. In the case of real multireservoir objects of development, when the parameters of each reservoir are not known for sure, the stabilizing techniques based on the fuzzy sets theory can be applied for the stability of solution.

Key words: simultaneous development of reservoirs, recovery separation, material balance, fuzzy sets theory, CRM.

Wells interference determination by permanent down-hole monitoring on base of sector modeling

Key words: decline analyze, well testing, Interference test.

Permanent down-hole monitoring interpretation efficiency in case of low permanent reservoir case with hydraulic fractures is presented at the paper. Producers and injectors simultaneous analysis on base of sector models tuned with PLT and well-test results provides well interference and hydrofracs orientation and distance between fracture tips. It’s very actual in case of water injection with pressure above fracturing gradient and long fracs implementation. On base of permanent down-hole monitoring JSC «Gazpromneft» optimize injection to reduce water-cut and afford pressure support. It results in additional oil production. Field cases are at the paper.

Key words: well completion, water-isolating screen, special cement blend, water contributing interval, water breakthrough,

A conceptually new completion method to prevent water cut of the wellstream resulting from bottom water breakthrough to the annulus is considered. The technology is realized at the stage of completion; it involves selective forming of a protective screen in the water contributing interval. The paper presents results of the analysis of the completion technology, as well as conclusions and practical recommendations.

African energy reserves and Russia’s interest in the continent

Key words: The oil resources of African continent. The gas resources of African continent. China's energy strategy in Africa. Usa's energy strategy in Africa. Russian energy strategy in Africa.

Second decade of 21st century carries many aspects: global crisis, slowdown of globalization, dynamical changes of World’s superpowers , therefore, inevitable changes in privatization on a global scale. In this context huge role plays practical interest of energy resources of Africa and a clash of interests of two superpowers- USA and China. Russian energy companies has its own global interests, and its crucial part is also in Africa. This is why for them, practical interest can be represented as an overall picture of energy resources on that continent and some tendencies of its exploration of leading companies from those countries which hold the position of a superpower.
