Section 1. General provisions

1. This Technique is developed according to subitem 16-1) of article 64 of the Code of the Republic of Kazakhstan "About subsoil and subsurface use" and establishes the single principles to classification of inventories of fields and forecast resources of minerals, the state accounting by degree of study and development.

2. Classification of inventories of the fields and forecast hydrocarbon resources including relating to nonconventional provides differentiation of inventories and hydrocarbon resources on groups, categories, on size, complexity of structure and extent of development of fields at development of fields of hydrocarbons and passing components.

3. Classification of inventories of fields and forecast resources of underground waters establishes single valuation principles and the state accounting of operational inventories and forecast resources of underground waters on degree of their study and readiness of fields for further studying and use taking into account nature protection and other restrictions according to requirements of the Code of the Republic of Kazakhstan "About subsoil and subsurface use" and the Water Code of the Republic of Kazakhstan (further – the Water code).

6) Off-balance inventories of solid minerals – inventories of solid minerals which use according to the approved standards, for count date, is economically inexpedient or technically and it is technologically impossible.

7) Off-balance inventories of hydrocarbons – not taken it is profitable from subsoil in case of the modern level of the equipment and technologies. Also inventories which in case of low-quality hydrocarbons, small performance of wells, limitations of inventories or special complexity of operation are not brought into development now belong to off-balance, but are considered as object for industrial development further.

8) Off-balance inventories of underground waters – inventories of underground waters use, which for assessment not acknowledged reasonable for the technical and economic, technological and ecological reasons which are directly not connected with the project of water intake (impossibility of alienation of lands, difficult mining-and-geological conditions, nature protection restrictions, lack of rational technology of preliminary water treatment or extraction of valuable components, change of social and economic environment, need of regulation of superficial drain, etc.).

9) the Deposit of hydrocarbons – the part of subsoil containing the isolated natural accumulation of hydrocarbons in the trap formed by breed collector and tire of impermeable rocks.

10) Inventories of hydrocarbons – the amount of hydrocarbons and the passing components containing in them in the revealed, reconnoitered and developed deposits given to standard (0,1 of MPa and 2 °C) to conditions.

11) the Preserved fields (deposits) of hydrocarbons – fields where prospecting or mining works, and the reconnoitered fields where carrying out development during certain period of time it is economically inexpedient are temporarily stopped.

12) Testing of well – the temporary operation of wells in the research purposes providing complex of the works providing inflow challenge, sampling of reservoir liquid and gas, layer oil and gas content identification, determination of the main hydrodynamic characteristics of layer (reservoir pressure, hydraulic conductivity, the productivity coefficient) confirmed with the Act of testing of well in any form.

13) Coefficients of oil recovery, gas and condensate – the sizes showing what part of inventories or resources is taken from subsoil in case of the optimum mode of development of deposits to limit of economic profitability.;

14) the Field of hydrocarbons – set of deposits of the hydrocarbons dated for one or several traps controlled by single structural element and located on one local square.

15) Inactive balance sheet inventories – inventories which do not provide return from investments, but working off of which is not unprofitable.

16) layer Approbation – the complex of works which is carried out for the purpose of challenge of inflow from layer, sampling of reservoir liquid, assessment of nature of saturation of layer and determination of the approximate output confirmed with the Act of approbation of layer in any form.

17) the Formation tester is set of the tools, devices and devices grouped together for accomplishment of number of functions when testing and carrying out measurements in layer.

18) Prepared for mining (deposit) of hydrocarbons – fields where study provides creation of the project of mining of oil or gas.

19) Forecast resources of underground waters is amount of underground waters of certain quality and target, assignment which is given within the hydrogeological region, river basin and the administrative area and reflecting potential opportunities of their use.

20) Hydrocarbon resources – amount of hydrocarbons and the passing components containing in them for date of assessment of the expected deposits which are not opened with drilling on the established structures or on the squares prepared for drilling in litologo-stratigrafichesky complexes with the proved or expected oil-and-gas content within large geostructural elements.

Contents in minerals of passing valuable, toxic and harmful components, forms of stay and feature of distribution in products of enrichment and factory repartition are at the same time determined.

8. On complex fields inventories of the main and together with them the lying passing minerals (minerals, chemical elements and their connections), economically reasonable for extraction are subject to calculation and accounting. For the valuable passing components accumulating in case of enrichment in saleable concentrates or products of metallurgical conversion both gross, and recoverable reserves are counted and considered.

Chapter 3. Grouping of fields (sites) of solid minerals on complexity of geological structure for the purposes of investigation

25. Reasonable extent of studying of fields (sites) prepared for industrial development is determined depending on complexity of geological structure and distribution of minerals, and also economic factors depending on them – the costs of means and time required on production of exploration works. Taking into account this field or the sites of large-scale deposits planned to working off by the independent companies for mining are subdivided into three groups.

The first group - fields (sites) of simple geological structure which prevailing part of inventories (more than 70%) contains in mineral bodies with undisturbed or slabonarushenny bedding, the sustained capacities, internal structure and quality of mineral with uniform distribution in them the main valuable components.

Features of geological structure of fields of the first group determine possibility of identification in the course of exploration of reserves of categories A, B, C1 and C2.

The second group - fields (sites) of complex geological structure which prevailing part of inventories (more than 70%) are characterized by changeable capacity and the internal structure of bodies of mineral broken by bedding, unrestrained quality of mineral, uneven distribution of the main valuable components, fields of simple geological structure, but with difficult mining-and-geological conditions of development.

Features of geological structure of fields of this group determine possibility of identification in the course of exploration of reserves of categories B, C1 and C2.

The third group - fields (sites) very much and very complex geological structure which main part of inventories (more than 70%) are characterized by sharp variability of capacity and internal structure, or intensively broken bedding of bodies of mineral or unrestrained quality of mineral and very uneven distribution of the main valuable components. On fields of the third group identification in case of exploration of reserves of categories A and B is inexpedient owing to the high cost of investigation and its low performance. Inventories of fields (sites) of this group razvedutsya generally on categories C1 and C2.

Chapter 4. Grouping of fields of solid minerals on study degree

26. Mineral deposits on degree of study are subdivided on: estimated, reconnoitered and operated.

Fields quality, technological properties, hydrogeological and mining conditions of development belong to estimated, inventories are studied in the degree allowing to prove feasibility of further investigation.

Fields, quality, technological properties which hydrogeological and mining conditions of development of inventories are studied with the completeness sufficient for the solution of questions of procedure and conditions of involvement of inventories in industrial development, designing of construction or reconstruction based on the mining company belong to reconnoitered.

The fields involved in industrial development belong to operated.

Chapter 5. Grouping of inventories of solid minerals on their economic value

27. Inventories of solid minerals and useful components containing in them on their economic value are subdivided into two groups which are subject to separate calculation and accounting: balance sheet and off-balance.

Balance sheet inventories are subdivided into two subgroups: active and inactive.

Off-balance inventories are counted and considered according to feasibility statements on standards where the possibility of their preserving in subsoil for the subsequent extraction or feasibility of passing production, warehousing and preserving for future reference is established. In case of calculation of off-balance inventories their division depending on the reasons of reference of inventories to off-balance is made (economic, technological, hydrogeological or mining conditions).

28. The inventories of solid minerals concluded in ore bodies, deposits of minerals, left for prevention of collapse of roof of clearing developments, tselika of large reservoirs and water currents, settlements, capital constructions and agricultural objects, reserves, nature sanctuaries, stories and cultures belong to balance sheet or off-balance based on special technical and economic calculations. In technical and economic calculations costs for transfer of constructions or special methods of working off of inventories are considered.

29. Balance sheet accessory of field reserves is established by the feasibility statement on standards for stock counting of minerals by results of state examination.

30. The inventories which passed state examination and positive are put on the state balance, including: balance sheet inventories on categories A, B, C1, C2, off-balance inventories without separation into categories.

Chapter 6. The formulas used in case of stock counting of solid minerals

31. The minimum industrial content is used as criterion for determination of balance sheet accessory of inventories in subcalculating blocks and determined analytically on the basis of the following ratio:  

 

where Smin - the minimum industrial content of useful component, % (if it is determined in grams (further –) on ton or cubic meter (further – m 3), the multiplier 100 of numerator is excluded); З - complete operating costs on production and conversion of 1 t of ore, $; C - sales price of unit of the products received in case of conversion of ores, $); And - end-to-end extraction of useful component in products from mineral raw materials, unit share; p - the coefficient considering impoverishment in case of production, unit shares.

The minimum industrial content, depending on type of the received products, is determined by the following formulas:

for the ores processed to saleable concentrates in case of the prices of concentrates with the established content of useful component

 

in case of the prices of the useful component containing in concentrates

 

for the ores processed to commodity metals with inclusion of enrichment repartition

 

for the ores processed to commodity metals without enrichment
