Enhanced onshore oil recovery through novel combine heat and power stirling technology

Island Gas Ltd (IGas) and Landfill Systems Maintenance Ltd (LSL) have developed a novel process to generateheat & power at onshore conventional oil wellsites. The process utilises low volume gas flows common to UKonshore extraction sites to power a novel combined heat and power (CHP) stirling engine. This will eliminateneed for grid electricity for pumping oil, with the heat used to separate oil & water at the wellhead (currentlytransported, collated and de-watered at remote processing centres). Gas utilisation will reduce back pressureat the well bore allowing for increased flow rates, enhancing production and extending reservoir life. This lowcost enhanced oil recovery process provides timely benefits for the operator and the environment in reducingmethane gas vented to atmosphere. Technology integration and validation will be carried out at IGas’sScampton wellsite, with engine modifications and monitoring being undertaken by specialist gas extraction andmangement firm, LSL. Demonstration of the system is scheduled 2016 with commercial deployment likely tocommence end-2017.
