Well Unloading & Blow Down

Well Unloading & Blow Down Picture Objective: Increase production from idle wells by flowing multiple low pressure or idle wells to surface using portable production equipment and using pumps to re-inject into the pipe line both liquids and gas. Can operate in conjunction with both gas lift and water injection to further increase production. Package can be operated to ensure no overboard emissions.

The well unloading packages handle low pressure production, boosting the oil and gas flow rates and processing them for re- introduction into the operator’s process plant facilities. The Production Solutions’ Low Pressure System is a system that utilises the well test unloading concept, using the common well testing equipment package, modified to reduced footprints. Packages are simple to assemble and designed to be quickly be mobilised between platforms.
