FORSA PAO23 Paraffin Inhibitor Eliminated Paraffin Deposition and Increased Production
An independent operator in the Eagle Ford Shale region of Texas flowed back several new wells, producing 50º API gravity oil. Paraffin deposition was extremely severe in the sales tanks and production was rejected numerous times. Tanks had to be hot oiled to sell the oil. The paraffin characteristics varied from 60-20º API gravity oil, and cloud point ranges of 70°F to 115°F, which led to flowline plugging. Surface vessels malfunctioned, tank bottom deposits increased, and oil sales tanks were rejected.
After being contacted to solve these production challenges, Baker Hughes, a GE company (BHGE) recommended a FORSA™ paraffin management program to help the operator overcome the severe paraffin deposition within the sales tanks. Application of FORSA PAO23 paraffin inhibitor reduced tank bottom deposits, lowered cold crude viscosity, and controlled paraffin deposition. The operator was able to increase tank capacity, decrease pumping costs, and reduce line maintenance. The BHGE FORSA paraffin management program increased revenue and eliminated costly shutdowns for the operator.
- Paraffin deposition was extremely severe in each flowline and all surface equipment, which led to downtime and costly cleanout jobs
- Cloud point ranges of 70°F to 115°F led to flowline plugging
- Unacceptable crude oil viscosity levels
- Tanks had to be hot oiled
- No pads or tank bottoms have been noted since initial treatment began
- Allowed optimum production rates without hot oil treatment of tanks
- Eliminated sales tank rejections
- Improved post-treatment production to 2,200 BPD at USD 100 per barrel
