ABERDEEN, UK -- BJ Services has released a new line of Dyna-Coil capillary injection systems. The artificial lift technology uses small diameter capillary strings through well tubing. This process feeds specialty chemicals, water, and solvents to aid production. The capillary strings can be run to depths of 22,000 ft (7,000 m).
According to BJ Services, more than 7,000 capillary strings using Dyna-Coil technology have been installed throughout Canada and the US, including Alaska and the Gulf of Mexico.
The product features InjectSafe wireline retrievable or tubing retrievable SCSSVs (surface-controlled subsurface safety valves). Both designs allow operators to feed chemicals through a capillary system without violating the integrity of the SCSSV.
"By using this system offshore we can economically treat wells subject to a number of production-related issues," says Umberto Micheli, region manager of Europe and Africa for BJ Services' well services division. "For example, wells with liquid loading, salting, scaling, or hydrate problems now can be treated with precision, at the perforations, without pulling the tubing to install a capillary string."
