BJ Services announced it has enhanced its well production services portfolio with Dyna-Coil™ capillary injection systems. BJ now offers effective artificial lift technology that uses small diameter capillary strings through well tubing to feed specialty chemicals, water and solvents to enhance production. The capillary strings can be run to depths of 22,000 ft (7,000 meters). Custom software is used to help operators select the most appropriate wells for these applications.

To date, more than 7,000 capillary strings using technology have been installed throughout Canada and the USA, including Alaska and the Gulf of Mexico. This technology has helped operators to maintain production and increase recovery from mature fields, particularly in lowpressure gas reservoirs. This emerging technology represents the first step toward changing methods of artificial lift for offshore wells.
