Tax incentives for the oil recovery stabilization and budget effectiveness of tax differentiation on the mining operations on Romashkinskoye oil field

DOI:

Given are the data, reflecting the efficiency of the system of Tax Incentives for oil recovery, introduced in the Republic of Tatarstan in 1995 in three lines: continuation of marginal and high flooded well stock operation; putting into operation of new wells, introduction of methods of enhanced reservoir recovery - and envisaging the reduction in excise tax, fee for recovered minerals, exemption of payments to the mineral resources reproduction fund. Shown is the efficiency of the introduction in 2006 of the differentiated tax on the mining operations on Romashkinskoye field, which allowed during 2007-2009 to get 3.556 rubles of additional taxes and fees on 1 ruble of allowances.

An alternative approach and the economic concept of classifying of oil and gas resources and reserves in market conditions

DOI:

An alternative approach and the economic concept of integrated assessment of oil and gas resources and reserves on the basis of rent theory, adapted to market conditions, are recommended. It is noted, that this approach is more perfect, science-based, increases validity of the resources and reserves classification, ensures the reliability of the optimal prediction of production, obtaining maximum net discount revenue, comparable to the foreign approach and has to supplement the project of a new classification of resources and reserves of hydrocarbons.

The use of project estimated well fund on underlaying objects for supplementary margin zones of stretches and top horizons

DOI:

Under still ongoing economic crisis operators make every effort to cut capital expenses on drilling of new exploratory and appraisal wells. For this reason Djalilneft NGDU uses the projected appraisal wells for supplementary exploration of edge by-passed zones and uppermost horizons. This will allow to identify new targets in the upper part of the cross-section, to improve well logging interpretation algorithm, to determine rock quality in the upper intervals, to position phase contacts, to assess oil reserves and to improve their category, and to optimize approved production systems with minimum costs.

Laboratory and theoretical researches of matrix acid-based carbonates processing

DOI:

The present paper represents the results of experiments made with the cores from carbonate formations with sand-a -levrolite layers. The experiments showed a strong influence of heterogeneity of the carbonate formation on its flow loss properties during acid treatment of formation. On the basis of the said experiments the averaged model of acid solution of the carbonate matrix was built which takes into account a possible accumulation of sediments. The mathematical model includes the empiric formula to determine the velocity of settled particles concentration and porous rock permeability change. Matching of the model with the real physical process is carried out through comparison of calculated gradient pressure value of the flow with the laboratory data obtained from core experiments.

The hydraulic fracturing influence on the development of the reservoirs in the Lower Oligocene of the White Tiger oil field

DOI:

The article discuses the example of the productive strata development in the Lower Oligocene reservoirs of the White Tiger oilfield considering particularly the influence of hydraulic fracturing on the energy state of the production zone. We show that the reduced duration of the effect of hydraulic fracturing results mainly from reservoir pressure drop due to increased fluid recovery and insufficient development of flooding system
