Tundra's Capillary Injection Solution - Artificial Lift in Monobore Wells
Field: Princess Field, Alberta
Casing: 4½”
Tubing: None
Pre-Capillary Production: 15 MCF/D
Post Capillary Production: 131 MCF/D
This commingled Milk River, Medicine Hat, Second White Speck well is completed with multiple perfs ranging from 415 to 677 mKB. The wellbore has no production tubing installed and therefore flows up the casing. The well was experiencing liquid loading problems as well as mud, silt and sand production issues when the client approached Tundra. The well was on a monthly swab program with a constant fluid level prior to capillary string install. On July 31, 2009 a capillary string was installed with the injection valve landed at the mid- point of the lowest perf interval, 675 mKB for continuous artificial lift. Injection rate started at 1 L/d and has been decreased to an optimized rate of 0.5 L/d.
The capillary foam system has lightened the hydrostatic head, enabling regular gas production to lift the fluid from the well which has eliminated the need to swab. The well has increased recoverable reserves significantly using 0.5 liters of surfactant per day; approximately $86/month in operating costs.
