METHOD FOR RECOVERY OF GASEOUS HYDROCARBONS AND/OR LIQUID HYDROCARBONS FROM UNDERGROUND Russian patent published in 2018 - IPC E21B43/267 C09K8/90 C09K8/92 

Abstract RU 2658953 C2

FIELD: mining.

SUBSTANCE: invention relates to the recovery of gaseous hydrocarbons and/or liquid hydrocarbons from subterranean formations. Method for recovery of gaseous hydrocarbons and/or liquid hydrocarbons from subterranean formations, characterised by the use of a polylactic acid resin comprising a component, which is a poly-L-lactic acid, and a component which is poly-D-lactic acid, while also having a specific heat of fusion at 190°C or higher, as measured by differential scanning calorimetry, of 20 J/g or more.

EFFECT: technical result is ensuring efficient extraction of shale gas, shale oil.
