Well Enhancement Strategy Inhibits Scale, Increases Production by 354.9 Mscfd
- Increased production by 354.9 Mscfd, resulting from a complex solution that was identified, designed and applied by Clariant Oil Services
- Enhanced production and management of a multitude of flow assurance challenges through product innovation
- Customized chemical delivery strategy with a value-added, service-driven approach
A low pressure, low rate gas well in Northern Alberta was sensitive to water production, and accumulation of produced water in the tubing would kill production.
Clariant Oil Services was successfully treating this well with a batch treatment program of WellBoost 131**, a high concentration, liquid chemical foamer and solvent combination. WellBoost 131 would bring the well back from a no-flow situation, and subsequent backside flushes and blowdowns kept the well producing, but eventually it would die off and the cycle would need to be repeated. Clariant Oil Services decided to take a fresh look at this well and re-evaluate the program being applied.
Clariant Oil Services Solutions and Value Delivered
After Clariant Oil Services’ investigation identified scale as a root cause of flow assurance failure, the well was batch treated with one drum of SCALETREAT SD 12900*** (a synergistic blend of inhibited acid and solvents) with a 6-hour soak. It was then brought back online with a continuous injection of 5 liters per day of WellBoost™ 302, a combined deliquification foam generation and scale inhibitor product. Production subsequently increased from the intermittent rates of 2 to 3 e3m3 (70.98 to 106.48 Mscfd) to initially 13.9 e3m3 (461.4 Mscfd) and a now stable 10.1 e3m3 (358.5 Mscfd) for at least four months. Clariant Oil Services’ commitment to continual improvement significantly benefited this operator with optimized chemical delivery yielding increased production.
