METHOD FOR UNDERGROUND RESERVOIR BUILDING IN ROCK SALT Russian patent published in 2005 - IPC

Abstract RU 2264965 C2

FIELD: liquid storage, particularly building underground reservoirs for liquid in soluble rock.

SUBSTANCE: method involves solving rock in several levels, wherein vertical preparation mine is preliminary formed before each layer solving. Natural gas is used as nonsolvent. Gas-brine interface is provided and maintained above top of level to be developed and natural gas is injected in vertical preparation mine. Then interface border is lowered to above top or below it. After level development the interface is increased and maintained above top of next upper level to be developed. All above operations are repeated at the next level.

EFFECT: reduced time of reservoir building and increased reliability.
