Solutions for Today's Chemical Injection Challenges
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 have plagued the industry for decades.
Chemical injection systems have historically had issues when reservoir pressures fall or are below the threshold required to maintain a stable column of chemical injection fluid in the control line. This U tubing effect is often the root cause of chemical injection system failure. Failure to properly size the control line based on fluid, hardware and well environment constraints has also been an issue.
To address these challenges, PTC has developed their SureFloTM TR2385 range of barrier certified chemical injection systems.
PTC's SureFloTM range of chemical injection systems provide:
- Anti U-Tubing protection
- Barrier qualified dual back check systems
- Shear disc to facilitate testing of control lines
- Shearable filter system
PTC has also developed their own proprietary software to simulate the entire chemical injection systems performance over the life of the well.
Life of Field Chemical Injection Design
PTC’s Life of Field chemical injection design software can simulate the entire chemical injection system and determine the optimum control line size, anti-u tubing setting and control line test pressure.
PTC has developed a unique Chemical Injection well design work-flow, which employs a combination of proprietary and industry recognized software tools. These tools cater for uncertainties and changes in key parameters over the life of the well. PTC’s design tools provide operators with all the information they require, to make the best Chemical Injection design selection decisions.
