Methods of stock counting of the minerals including relating to nonconventional hydrocarbons

Chapter 1. General provisions

1. These Methods of stock counting of the minerals including relating to nonconventional hydrocarbons (further – Techniques), are developed according to subitem 16-2) of article 64 of the Code of the Republic of Kazakhstan "About subsoil and subsurface use" (further – the Code).

2. Techniques determines single requirements, the principles, conditions and procedure for stock counting of mineral deposits, their revaluation, and also preparation of materials for representation for state examination of inventories.

3. Techniques determine:

general methodological bases of stock counting of minerals;

requirements to the basic geological, technical and economic data used in case of stock counting;

requirements to reasons for the accepted calculated parameters and indicators;

general approaches to classification, assessment and confirmation of inventories of minerals.

4. Techniques are directed on:

ensuring reliability, completeness and justification of count results of inventories of minerals;

forming of uniform practice of stock counting in the territory of the Republic of Kazakhstan;

ensuring comparability of results of assessment of inventories;

creation of basis for decision making on rational use and protection of subsoil;

ensuring stock accounting in the state balance and their representations for state examination.

5. Techniques are applied by subsoil users, and also other physical persons and legal entities which are carrying out works on studying of subsoil, calculation and revaluation of inventories of minerals in case of:

conducting exploration works;

to preparation of reporting materials on stock counting;

representation of materials for state examination of inventories;

modification of earlier approved inventories.

6. Requirements of these Techniques are obligatory in case of calculation and revaluation of inventories of mineral deposits in the territory of the Republic of Kazakhstan.

7. Techniques include:

Method of stock counting of solid minerals;

Method of calculation of operational inventories of underground waters;

Method of stock counting of the hydrocarbons including relating to nonconventional hydrocarbons.

The basic concepts used in technique:

1) standards on mineral raw materials - represent set of parameters, being guided by which inventories of mineral deposits and their balance sheet accessory are determined. They are established on the basis of the comprehensive analysis geological, mining, technological and environment of development of mineral deposits which degree of study is sufficient for allocation of inventories mainly of categories B and C1.

1) assessment currency – the monetary unit used for assessment of the investment project. For measure calculations of assessment as monetary unit it is offered to use US dollars. The reporting of the subsoil user in the form of the working program and other obligatory indicators for tasks of the contract is made in national currency of the Republic of Kazakhstan, at the rate for date of assessment;

2) basic well is well where in the considered interval the full range of geophysical surveys of wells, the selection and researches of core, layer testing allowing to determine most authentically intervals of collectors and filtration-capacitive properties is executed (further – FES);

3) model of single-phase filtering – in case of hydrodynamic modeling is represented by circles of monocomponent mix (oil, natural gas) in which interaction happens at the molecular level and interface it is impossible to allocate. The system contains and in it there is filtering only one phase / one type of fluid;

4) gas hydrates – solid crystal substances of natural origin in case of which disintegration gas with the prevailing methane content is emitted;

5) geological inventories – the inventories of hydrocarbonic raw material which are in deposits;

6) the model of two-phase filtering – in case of hydrodynamic modeling of two-phase filtering is considered joint filtering water and oil. Isothermal movement of two immiscible liquids in the porous circle is considered;

7) the discounted investment payback period – the period since the beginning of assessment to the first year of assessment in case of which the total discount cash flow of the subsoil user becomes positive;

8) discounting – method of reduction of costs occurring at different times and the income on the project to single cost assessment on start date of assessment. For calculation of regulation of discount it is offered to proceed from the amount of capital cost, inflation and remuneration for risk of the performed investments. In the absence of reasons for discount rate it is offered to use discount rate in the amount of 10% (ten percent);

9) simple payback period of investment of the subsoil user – the period since the beginning of assessment to the first year of assessment in case of which the total cash flow of the subsoil user becomes positive;

10) internal regulation of profitability of the subsoil user – value of discount rate in case of which the discount cash flow of the subsoil user for the profitable period of assessment is equal to zero;

11) index of profitability of the subsoil user – the relation of the net total discounted revenue to the total discounted amount of capital investments for the profitable period of assessment;

12) breed collector – the breeds capable to contain oil, gas, water and to give them in case of development even insignificant quantities;

13) porosity of breed is property which determines reservoir of breed, and represents the relation of amount of all emptiness to the total amount of breed;

14) permeability of breed – capability of breeds of layer to pass liquid and gas in case of pressure difference;

15) filtration-capacitive properties of breeds are properties which are determined by means of the key physical parameters: porosity, permeability and water saturation. They determine capability of collectors to contain and filter fluids which movement happens or owing to natural processes (migration of hydrocarbons), or as a result of the activities of the person connected with extraction of minerals;

16) the settlement term (period) of development – time which passed since the beginning of commissioning of the field (operational object, deposit) before shutdown of the last production wells of operational fund for the limiting criteria in case of the most complete scope of deposits replacement process;

17) mathematical models of isothermal single-phase filtering in the isotropic porous circle consider the mass conservation law, law of conservation of momentum (in the form of the law of filtering Darci) and the determining equations in the form of dependence of density, porosity, permeability, viscosity on pressure;

18) inflation – indicator the considering growth of overall price level and costs which is followed by loss of purchasing power of monetary unit. Measure calculation of assessment is offered to be made in current prices, that is with inflation indexation. Inflation is applied as to project revenues (staple price less transportation expenses), and to account part of the project (the capital investments, operating costs, taxes attributable to deductions). The coefficient of inflation is accepted as average on historical values for the last 3 years prior to year of assessment;

19) geological and hydrodynamic model of the field – the set of digital three-dimensional array of geological and physical parameters characterizing the modelled field (deposit, operational object) and corrective actions on it in the course of development describing the main patterns of filtering formation fluids under the influence of these impacts and the applied technical technology solutions;

20) deposit – accumulation of hydrocarbonic raw material in the natural single hydrogasdynamic reservoir dated for one layer collector, two-three and more reported layers collectors of section or for big thickness of breeds collectors of the field. The quantity of deposits in geological section of the field corresponds to amount of productive layers or to be less it;

21) the water saturation of collectors – characterizes content of reservoir water in collector. When forming deposit part of water remains in hollow space of collector. This water containing together with oil or gas in deposit is called residual water. The amount of residual water in deposits depends from FES of breeds: the extent of emptiness and permeability of collectors is less, the its is more;

22) condensate – natural mix of generally easy hydrocarbon compounds which are in gas in dissolved condition under certain thermobaric conditions and passing into liquid phase in case of pressure decrease is lower than condensation pressure;

23) hydrocarbonic raw material – crude oil, gas condensate, natural gas and associated gas, natural bitumen, and also the hydrocarbons received after purification of crude oil, natural gas, processing of combustible slates and resinous sands;

24) the field of hydrocarbonic raw material – part of the subsoil containing natural accumulation of hydrocarbonic raw material in one or several delineated deposits dated territorially for one area and connected with favorable tectonic structure or with other types of traps;

25) inventories of hydrocarbonic raw material – the mass of oil, condensate, and also the gas amount in the revealed, reconnoitered and developed deposits provided to standard (0,1 of MPa and 20 0C) to conditions;

26) multicomponent (composition) model of filtering - composition models of filtering are used in case of detailed modeling of deposit, containing light hydrocarbons (condensate and gas) in that case when it is necessary to describe mass exchange between phases when formation fluids contain not hydrocarbon components. Fluids are in layer not to the isothermal circle (temperature not constant and change in process of conducting development of deposit);

27) contact oil-water represents the surface close to horizontal or inclined plane. The surface of gas-water contact (further – GVK) often horizontal, however, cases and inclined contacts are available;

28) the profitable geological inventories (taken) – part of geological inventories which extraction is economically reasonable when using of the modern approved technologies and the equipment with observance of requirements for protection of subsoil and the environment;

29) unprofitable geological inventories – inventories which extraction when using of the modern approved technologies and the equipment with observance of requirements for protection of subsoil and the surrounding environment is economically inexpedient;

30) natural bitumen – the minerals of organic origin with primary hydrocarbon basis lying in subsoil in firm, viscous and viscoplastic condition;

31) slate gas – the multi-component mixture of hydrocarbons and not hydrocarbon gases with the prevailing methane content which is in gaseous state at normal atmospheric temperature and pressure, containing in slate breeds;

32) slate oil – the crude oil containing in slate breeds;

33) the transportation price – the transportation cost of hydrocarbons is determined proceeding from the actual transit fares (pipeline, railway and others) on date of assessment. When calculating clean price (net back) of staple price decrease by transportation cost;

34) technological losses – the irretrievable losses of hydrocarbons connected with implementable engineering designs of arrangement of fields, caused by technological features of production cycle, and also physical and chemical characteristics of the extracted hydrocarbons. Value of percent of technological losses will be determined on the basis of actual data of the subsoil user. When calculating net profit technological losses of hydrocarbons are subtracted from the total amount of the extracted raw materials;

35) geophysical surveys of wells (further – GIS) – complex of the methods of prospecting geophysics used for studying of properties of rocks in okoloskvazhinny and interborehole spaces. And also for control of technical condition of wells. GIS are carried out for studying of geological structure of section, release of productive layers (first of all, on oil and gas), determinations of collection properties of layers;

36) three-dimensional geological model – creation of three-dimensional structural maps, cubes of subcalculating parameters based on seismic yielded and results of well-drilling (GIS, core, testing, etc.), with automatic interpolation between wells by different statistical techniques (continuous, stochastic and others). Calculation of initial amounts of hydrocarbons in bedded conditions happens directly on cells of three-dimensional model. Modeling to be carried out on the specialized software;

37) model of three-phase filtering – in case of finding of oil in layer in mix with free water, in case of pressure decrease lower than pressure of saturation is initiated liberation of gas, and in layer the mobile three-phase system "oil-water-gas" is formed;

38) raw materials sales prices – the prices of hydrocarbons in the external and internal markets needs to be determined on the basis of actual data of the subsoil user on date of assessment or the forecast macroeconomic indicators represented by authorized state bodies or the statistical agencies;

39) economic criteria – efficiency of the project is estimated by system of the calculated indicators acting as economic criteria.
