Abstract: Sizing the correct tubing diameters to exceed critical flow velocities to lift fluid, while utilizing polymers to dramatically reduce the pressure drop created by the high velocity flow rates allows low pressure wells to continuously lift fluid without the need for artificial lift technologies. The oil and gas industry experience with polymers has primarily focused on low pressure polyethylene tubing for gathering lines and gas distribution. The benefits include excellent corrosion resistance, low cost installation and reduced pressure drops versus steel. Polyflow Inc has expanded upon these benefits with higher strength polymers, reinforcement braiding and well modeling capabilities to provide tubing sized to lift both fluid and gas in marginal wells without creating excessive backpressure against the formation. The constant flow of gas and fluid mist results in very stable gas production and fluid removal without continual well operator intervention.
