DIFFERENTIATION OF WELL PRODUCTION AT MIXING OF TWO SEAM PRODUCTS Russian patent published in 2014 - IPC E21B47/00 

FIELD: oil-and-gas industry.

SUBSTANCE: well production at mixing of two well products by preliminary sampling of every productive seam with determination of reference component, subsequent sampling of representative product and determination of desired production quantity for every seam by computation. Note here that said reference component for differentiation of extracted oil and formation waters represents an arbitrary stable reference component including total content of definite (particular) hydrocarbons in extracted products the content of which differs notably for oils, while differentiation of formation fluids is executed by stable reference component, that is, total mineralisation. Formation fluid total mineralisation is evaluated after its complete removal from mouth sample with subsequent water evaporation from standard weight, dry residue is weighed and dissolved in distilled water. Mechanical impurities not dissolved therein are separated the weight of which are not allowed for in determination of total water mineralisation.

EFFECT: higher accuracy.
