Scientists from Perm Polytechnic University (PNIPU) have developed a method for predicting hydrate formation in oil wells.
During the development of oil and gas fields, deposits form in the wells – hydrates, which clog equipment and reduce flow rates.
Specialists from PNIPU have developed a methodology for predicting hydrate formation intervals under conditions of constant and periodic operation of electric submersible pumps. The methodology proposed by the scientists allows predicting the depth of the onset of deposition with an accuracy of up to 90%.
During the analysis, we identified parameters that affect the intensity of hydrate formation: a high gas factor, pressure at the intake of electric submersible pumps below the saturation pressure, and high water cut of the oil.
Earlier www1.ru reported that scientists from KFU have created effective inhibitors — substances that slow down chemical reactions. They will help prevent the formation of hydrate plugs in gas pipelines and technological systems during the extraction and transportation of oil and gas.
