METHOD OF BURIAL OF DRILLING AND PROCESS WASTES DURING OPERATION OF OIL AND GAS CONDENSATE, OIL AND GAS DEPOSITS Russian patent published in 2024 - IPC B65G5/00 E21F17/16 B09B1/00 

FIELD: processing and recycling of wastes.

SUBSTANCE: invention relates mainly to oil and gas industry and can be used in burial of drilling wastes and other process wastes in underground reservoirs, created, in particular, on offshore fields and/or in conditions of the Far North. Method of burial of drilling and process wastes during operation of oil and gas condensate, oil and gas deposits by their injection into the well includes determination of strength properties of fluid seals on the basis of petrophysical investigations and geomechanical data in at least one formation of deposits. Method is implemented with subsequent monitoring of fracture closure pressure at least in one point of bottomhole formation zone with subsequent comparison of current stress in the formation after each cycle "injection–shutdown" during shutdown, with limits of strength of fluid seals, determined before the beginning of injection. At that, pumping of drilling and process wastes is carried out till the moment of achievement of strength properties of fluid seals determined before the beginning of pumping.

EFFECT: improving reliability and safety of operation of deposits due to continuous monitoring and control of integrity of fluid seals.
