Single rules on rational and complex use of subsoil in case of exploration and production of minerals

1. General provisions

1. Single Rules on rational and complex use of subsoil in case of exploration and production of minerals in the Republic of Kazakhstan (further - Rules) are developed according to the subitem 3) of article 16 of the Law of the Republic of Kazakhstan of June 24, 2010 "About subsoil and subsurface use".

2. These rules determine single procedure by rational and complex use in case of exploration and production of minerals.

3. In these rules the following basic concepts are used:

sewage - the waters which are taken away after use in household and productive activity of the person or the contaminated waters which are subject to removal from the territory of settlements and industrial bodies;

geological inventories - the inventories of hydrocarbonic raw material which are in deposits;

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

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;

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 °C) to conditions;

test operation of deposits of hydrocarbonic raw material - the operations performed on oil and oil and gas fields and providing temporary operation of the drilled exploratory wells;

regulation of development of deposits of hydrocarbonic raw material - process control of extraction of hydrocarbonic raw material by means of complex of different technological and technical actions;

the fields having complex geological structure - fields which more than seventy percent of inventories are characterized by variability of capacity or the broken bedding of bodies of mineral or unrestrained quality of mineral and uneven distribution of the main valuable components, or heterogeneity of collector or collection properties of productive layers, or abnormally high reservoir pressure;

extraction unit - the smallest economically and technologically optimum site of the field with reliable calculation of initial inventories (the block, the panel, lava, part of ledge) which working off is performed by single system of development and the technological scheme of dredging, by which the most exact separate production accounting by quantity and quality of mineral can be performed; 

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;

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;

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 can correspond, to amount of productive layers or to be less it.
