METHOD OF YIELD DETERMINATION OF WATER, OIL, GAS USING FLOW METER Russian patent published in 2015 - IPC E21B47/11 

FIELD: chemistry.

SUBSTANCE: invention relates to oil and gas industry, in particular to production wells operation, and can be used during development of oil, gas and gas condensate fields. Upon the method implementation on the well at least one chamber is installed, it contains tracer-marks with further quantitative monitoring of the well fluid for the tracer-mark content in the well fluid flow. The chamber is made with possibility to release the tracer-mark under external effect. The chamber is installed on the completion equipment and/or at wellhead through them the well fluid flows. In chamber at least one tank is installed, it has form of container or matrix, at that the container or matrix are made with possibility of destruction under action of water, or hydrocarbon medium, or hydrocarbon gas. The container or matrix of each type contains non-soluble particle 1-100 mcm and/or substances with high dielectric permeability as the tracer-marks.

EFFECT: increasing of the obtained information about reservoir filtration and actual processes in well with time and place specification.
