Hydroacoustics Inc. (HAI) has developed and successfully deployed a simple, rugged, well-designed system that uses very low frequency sound technology to recover additional oil from developed oilfields.
The system, known as the Oil Recovery Tool System (ORTS) employs very low frequency (VLF) sound waves of 100 hertz or less to stimulate or otherwise increase the flow of trapped oil. VLF stimulation enhances oil recovery by creating pulsed pressure waves that coalesce and mobilize oil droplets at a molecular level.
The ORTS is comprised of three major components:
- A down-hole tool (ORT) which is the acoustic generation unit. It is deployed into a wellbore across the productive interval to be stimulated. It utilizes high-pressure water to generate the pulsed pressure waves
- A Control, Diagnostic and Telemetry (CDT) manifold that operates and monitors the system. The CDT sends alerts and data to a remote receiving station via satellite uplink and/or the Internet
- An optional Topside Power Supply (TSPS) that allows the ORTS to operate on a stand-alone basis. The TSPS includes power generation, power distribution, a high-pressure pump, and water filtration system. The TSPS operates with on-site water storage to drive the ORT unit with high-pressure water
