METHOD DETERMINING QUANTITY OF HYDROCARBON STARTING MATERIAL IN RESERVOIR Russian patent published in 1998 - IPC

FIELD: oil and gas industry, petroleum refining industry. SUBSTANCE: given method includes measurement of hydrostatic pressures P₁ and P₂ by transmitters installed at level of water and oil levels with subsequent calculation of oil mass by dependence M_oil= C₀+C₁P₂-C₂P₁. Correction of measured pressures P₁ and P₂ depending on change of densities of water and oil is carried out by calculation formulas. Method makes it possible to exclude measurement error caused by change of densities of water and oil. EFFECT: improved accuracy of method. 4 dwg
