    "abstract": "The ability to monitore bottomhole flowing pressure in pumping oil wells\nprovides important information regarding both reservoir and artificial lift\nperformance. Converting surface pressure measurements to bottomhole is\ncurrently accomplished by locating the fluid level in the annulus using a sonic\ndevice and then applying a correlation to estimate the density of the gas-cut\nliquid column above the perforations. This work proposes a flowing bottomhole\npressure calculation procedure from fluid level measurements. The model is\ndeveloped from experimental work and from theoretical arguments. The\ncalculation procedure developed allows to calculate BHP without shutting the\nwell, which is common for fluid level casinghead pressure measurements. Also\nthis method allows to take into account real geometry of the The comparison of\nthe calculated and measured pump intake pressure shows good accuracy of a\ntechnique. It allows to draw a conclusion for an opportunity to use this method\nin practice.",
