Wells with scale or corrosion issues often require the continuous injection of treatment chemicals. The most common method employs the use of control lines to place the chemicals at the desired injection point in the well. Issues associated with the stable flow of chemicals through the control lines (no u-tubing), testing of control lines and well integrity have plagued the industry for decades..
Petroleum Technology Company’s SureFloTM chemical injection sub has a unique design, which utilizes the barrier technology from the PTC’s SafeLift valve. The SureFloTM sub facilitates testing of control lines, stable flow of chemicals (no u-tubing) and maintains well integrity.
