Key words: fiber, fiber-cement slurry, lost circulation, injectivity.

TatNIPIneft has developed a remedial cementing technology to fight lost circulation issues. The technology uses cement compositions with reinforcing fiber additives. Reinforcing fiber is made of thermoplastic polymer and has a cylindrical shape. Cement systems are characterized by high mobility, enhanced sedimentation stability, reduced water loss, good mudding off properties, ensuring high set strength. Out of seven remedial jobs performed in TATNEFT wells, six yielded positive results.

Key words: operational control, oil production, business processes, customer- contractor interaction.

ARMITS Corporate Information System is the main system of operational control and monitoring of oil production processes in Tatneft OAO. The efficiency of reserves development is attained through providing the user with a wide range of tasks that cover all key business processes in a single database with a complete list of indicators related to oil recovery and operation of production facilities

Key words: water-producing wells, oil production costs, down-hole gravity separation, double-action pumping system, ESP pumping system, intake formation, dump flooding to maintain reservoir pressure.

This paper discusses some aspects of improving water-producing wells operation through the use of double-action ESP pumping systems for dump flooding to maintain reservoir pressure. These pumping systems provide for down-hole gravity separation of crude oil and associated water. Then, either low-water-cut oil is produced to the surface while most of the separated water is injected to the intake formation without its lifting to the surface, or oil and water are lifted to the surface separately. In addition, ESP systems ensure low-cost control of oil-water mixture/separated water ratio, as well as the injected water quality control.

Key words: internal corrosion, galvanic anode protection, pipeline, electrically-insulating joints.

The paper presents performance characteristics of electrically-insulating joints in the cathodic protection systems of pipelines based on the results of bench testing. It has been offered to use efficiency coefficient of electrically-insulating properties characterizing the amount of protective current that remains once electrically-insulating joints have been installed as the main characteristic of an electrically-insulating joint. It has been shown that the more reliable protection of the pipeline, the more stray current flows through the electrically-insulating joint, i.e. the same electrically-insulating structure would be characterized by different efficiency coefficients (resistance to corrosion) in different cathodic protection systems.

Key words: scale precipitation in oilfield lines, casing head pressure increase, increased oil underproduction, scale precipitation inhibitors, barium sulphate deposition, sulfuric acid slug injection, critical concentration of barium ions and sulphates mixture.

The problem of scale precipitation in field gathering lines and process facilities of Oil and Gas Production Department Almetyevneft still persists. Scale precipitation occurs when critical mass of salt present in the wellstream has been exceeded. Salting-up is fraught with serious problems: narrowing of pipe ID with the resulting decreased throughput, underproduction due to increased casing head pressure and idle time while workover jobs, as well as escalation of operating costs associated with remedial actions. Early detection of salting-up drivers and prevention thereof is particularly critical for mature-stage fields, when cut-down of oil production OPEX is among top-priority objectives.

Key words: estimation of reserves, stochastic modeling, volumetric method of reserves estimation, 3D-modelling, controlled data reduction, distributed computing.

The problem of reservoir estimation on stochastic geology models is a pressing challenge, but standard methods are not defined yet. The article describes a method allowing to estimate bounds and most probable values of hydrocarbon reserves by means of multirealzation 3D models and distributed computing. The article provides results of computing experiment performed on the base of suggested method.

Key words: method of nuclear magnetic resonance (NMR), the phase transition, the crystallization of wax, paraffin oil saturation temperature, activation energy, wettability of the surface.

The article has investigated the effect of temperature on the pore space and the character of crystallization of waxes in the light of structural and lithological rock properties and composition of the oil fields as an example of the Perm region. Analysis of experimental data showed that the phase transition of paraffin in a restricted micro volume of reservoir rocks is observed at a temperature of 2-25 °C higher than the free volume. Significant role in the saturation temperature have physics-chemical characteristics of the pore surface. For carbonate reservoirs established a linear increase in the saturation temperature of paraffin oil with an increase in wettability of pore surfaces.

Key words: Government policy, guaranty of energy security, net importer of oil, strategic oil reserves, diversification of oil and gas supply routes, acquisition of foreign technology and companies.

The article is dedicated to certain aspects of the policy of the Government of the Peoples’ Republic of China in the sphere of oil. It describes the main achievements of the country in developing its oil and gas fields, analyzes the problems impacting on the growing dependence of China on oil imports and threatening the country’s energy security. Also treated are the key measures directed towards guarantying energy security, such as building up strategic oil reserves, creating an international market for oil futures, conditions for gas liquefaction and transportation. The Article summarizes Chinese experiences in diversifying oil and gas supply routes to improve the security of supply and reduce the dependency on the throughput capacity of the Strait of Malacca, as well as those in attracting private investment to the oil industry and acquiring foreign technology and assets. The Chinese policy “Loans in exchange for resources” is analyzed using concrete examples.
