Meeting the challenge of enhanced oil recovery

Silverwell, a provider of innovative solutions to the oil and gas industry, today unveils a new technology that is designed to meet the challenge of Enhanced Oil Recovery (EOR) head-on.

The DIAL (Digital Intelligent Artificial Lift) 350 is the first tool developed by Silverwell and delivers significant operational advantages. The real time gas injection technology is installed directly in the production tubing and with full digital, intelligent electronic control from the surface via permanent cable. Among its many benefits, it eliminates the need to use side pocket mandrels, wire line retrievals or well intervention techniques.

Not only does the DIAL 350 eliminate intervention costs it also provides continuous, more stable production. Six injection orifices, fitted with V0 reverse flow check valves, each individually controlled from the surface have a full spectrum of injection rate options. This means it is not reliant on a specific annulus pressure to maintain gas injection rates. Pressure sensors are included in the unit configuration at the point of gas injection to provide annulus and production tubing pressure and temperature data.

The actuators controlling the gas injection points are capable of operating at pressures up to 3600 psi, so even during modification to gas injection rates, the well maintains continuous production.

Peter Watson, chief technology officer for Silverwell said: “New technology and more intelligent approaches will define the future of our industry. We must be bold enough to invest what we can in new techniques to improve efficiencies across the board.

“Our DIAL 350 technology addresses this in the field of EOR. Using our patented, ultra-low energy Binary Actuation Technology (BAT) we can address the challenges of oil recovery lift and deliver continuous, more stable production. DIAL 350, delivers results from day one, with a return on investment from the first gas injection rate change.”
