METHOD OF DUAL-COMPLETION PRODUCTION FACILITY PRODUCTION CURRENT SEPARATE ACCOUNTING Russian patent published in 2017 - IPC E21B47/10 E21B49/08 

FIELD: oil and gas industry.

SUBSTANCE: method involves the selection of wellhead samples of the product, that is, a natural hydrocarbon mixture from each production single-layer object. Subsequent sampling of product wellhead samples from the dual-completion production facility and statistical processing of the data obtained. Investigations of the natural hydrocarbon mixtures (oil) dynamic viscosity of wells are held in which separate product record is carried out by the delves, for example, the first delf in the first well and the second delf in the second well. Then, samples of natural hydrocarbon mixtures are prepared by means of dehydrating, samples of single-layer objects are mixed in specified proportions, and then the dynamic viscosity of the resulting model mixtures are investigated. Studies of the resulting model mixtures dynamic viscosity are carried out, the dependencies between the content of oil of each of the delves in the model mixtures and the dynamic viscosity of the model mixtures are defined in the form of polynomial dependencies and the proportion of each of the delves in the dual-completion object oil is subsequently determined.

EFFECT: increased accuracy of determining the relative capacity by delves and shortened study period.
