VOLUME OF NATURAL GAS LOSS IN GAS AND GAS CONDENSATE FIELD WELLS

Abstract

Recently, the number of hard-to-recover gas reserves has been
increasing worldwide. At the same time, issues related to water encroachment
and the efficient operation of productive wells under complex conditions have
become increasingly relevant. Water influx in gas and gas condensate wells causes
serious operational challenges. In the final stages of development of gas and gas
condensate fields, due to declining in reservoir pressure and inflow rates, fluid
accumulates in the bottomhole zone of wells. This, in turn, leads to increased
pressure loss, reduced well flow rates, and decreased reservoir capacity to yield
hydrocarbon components. Currently, the blowdown method is used to address
this issue. This method, based on the direct release of gas into the atmosphere,
results in gas losses and has a negative impact on the environment and areas
surrounding the well. This article analyzes the blowdown method used to remove
fluid accumulation from the bottom of gas and gas condensate wells in the
Republic of Uzbekistan, as well as the volume of natural gas losses resulting from
the spontaneous shutdown of wells.
