METHOD TO MEASURE OIL WELL CAPACITY ON GROUP METER STATIONS Russian patent published in 2015 - IPC E21B47/10 

FIELD: measurement equipment.

SUBSTANCE: measurement of capacity of oil wells connected to a group meter station is carried out by a well switch simultaneously in all connected wells without one in turns and serially, further they determine results of calculation of each well capacity using the formula:

Q_i=Q_Σ-Q_Σ-1,

Q_i - debit of "i" well, connected to the group meter station; Q_∑ - total capacity of all wells connected to the group meter station; Q_∑-i - readings of flow meter of the total capacity without one (i) well; $${\displaystyle \sum _1^n{Q}_{{\displaystyle \sum -i}}}$$ - measured total capacity of wells in turns without one "i" well; n - number of wells connected to the group meter station.

EFFECT: increased accuracy and quality of measurement of capacity in oil wells connected to a group meter station due to efficiency of summary and alternate measurement of each well capacity, provision of sufficient time for true measurement of each well capacity.
