METHOD FOR DETERMINATION OF RESIDUAL GAS CONTENT IN FLUID Russian patent published in 2014 - IPC E21B47/10 E21B43/34 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil producing industry. The method includes procedures for measurement of initial gas content in the fluid and of the volume of gas released from the fluid. At that initial gas content in the fluid is determined for each group of oil producing wells operated in the common pipeline. Remaining gas content in the pipeline liquid is determined after gas extraction from skim pile according to the following formula: $$G=\frac{{\displaystyle \sum _{i=1}^n\left(Gi\cdot Qi\right)}-Qg}{{\displaystyle \sum _{i=1}^{n}Qi}},$$ where Gi is initial gas content in the fluid in the i well; Qi - liquid rate for the i well; n is a number of wells in the group operated in the common pipeline; Qg is volume of gas released from the pipeline liquid in skim pile per a time unit.

EFFECT: determining remaining gas content after degassing of a group of wells in gas separator before further extraction to oil pipeline.
