METHOD FOR DETERMINATION OF BOTTOMHOLE PRESSURE IN OIL WELL EQUIPPED WITH ELECTRIC SUBMERSIBLE PUMP Russian patent published in 2014 - IPC E21B47/06

Abstract RU 2515666 C1

FIELD: oil and gas industry.

SUBSTANCE: method lies in measurement of the maximum dynamic head depth for the known well-killing fluid with homogeneous density when bringing the well on to stable production after killing according to the following formula P_bthp=ρ_kf.·g·(H_perf-H_DHmax), where ρ_kf - density of the well-killing fluid, kg/m³; g - acceleration of free fall, m/s²; H_perf - height of the upper perforated openings, m; H_DHmax- maximum dynamic head depth in the well when bringing the well on to stable production after killing, m.

EFFECT: reducing downtime during well surveys, improving accuracy and reliability while determining the bottomhole pressure and simplifying of the bottomhole pressure measurement when bringing the well on to stable production after killing.
