PROCESS DESCRIPTION: Oil and gas products are brought to the surface. These products
go through a separator where the oil and any water products are
sent to storage tanks and the gas is used to power equipment on
site (pump jack engine, tank heater, separator, flare, combustor,
etc.) Any remaining gas is sent to a pipeline that feeds a local gas
plant. The oil and process water in the storage tanks is loaded
into tanker trucks and hauled off-site for processing and disposal.
