SEPCOR’s SE-300 solvent is a complex blend of broad range solvents for use in removing and controlling paraffin and asphaltene deposits in production operations. SE-300 is an oil soluble, non-ionic liquid that will effectively remove and help prevent paraffin and asphaltene deposits in crude oil production wells, equipment and storage facilities. SE-300 will aid in the demulsification of paraffin stabilized emulsions by reducing the organic solids content of the interface in treaters and tank bottoms. SE-300 is non-emulsifying in most systems.

Application

SE-300 can be applied by either batch or continuous treatment. Batch treatment is the most effective application for paraffin and asphaltene clean up in wells, flow-lines, and storage tanks.

To remove parafin and asphaltene deposits from the formation and down-hole area, SE-300 can be applied as batch and soak treatment, circulated, or as a squeeze. For most applications, 1 to 8 drums is used and needs 12 to 24 hours soak time or can be circulated for 8 to 12 hours to remove deposits through the perforations and in the near well-bore formation area, the product should be displaced with at least a tubing volume of clean crude. Allow this treatment to soak for 12 to 24 hours. After the soak or circulation period, the well is returned to production.

Case Histories SE-300

Case 1

A Wind River Basin well in Fremont County, Wyoming. The well produces from the Frontier Formation making 20 bbls of 7-8% paraffinic oil and 70 mcsf of gas. Production was decreasing due to paraffinic sludge in the near wellbore area. The producer hot oiled the well monthly resulting in a 20 Bbl./day increase. The well would gradually drop back to the original production level over the next 3-4 weeks.

Case 2

SE-300 was pumped down backside and circulated for 24 hours before the well was put back into production. SE-300 treatment volume was 220 gallons. Initial returns contained significant amounts of sludge and paraffin. Production increased from 20 bbl/day to 80 bbl/day. There was an increase in gas from 70 mscf/day to 125 mscf/day.

Case 3

The subject well is in the Wyoming Big Horn Basin completed in the Tensleep formation. Production rates were 32 bbl oil and water. Suspected damage from completion fluids and/or drilling muds. Past attempts to cleanout damage by other venders and service companies failed with one attempt actually creating a heavy asphaltene sludge thus reducing production rates further. Using a selective perf wash tool, the well was treated with 20 gal/ft of SE-300 and displaced with 15 gal/ft of xylene. Following the workover, the well peaked at 145 bbl/day before stabilizing at 112 bbl/day and 0 water. Our target of 52 bbl/day was doubled.
