Production Pipe Recovery SAG-01
Case In Brief
8” Production Pipeline:
- The problem started since Oct. 2006 during workover for well SE-5A.
- Partial plugging for the 8” production line from May 2007 till Nov. 2010.
- On Nov. 2007 using EDTA + HCl for cleaning 100 m led to incremental increase in production (Temporary Solution).
- On Nov. 2009 using soda ash + HCl for cleaning 3 Km led to incremental increase in production (Temporary Solution).
- The operating company assigned SAPESCO Company for cleaning the production line by new scale dissolver SAG-01 for the 1st time in the world.
- On Nov. 2010 using SAG-01 for cleaning 11.5 Km and the incremental increased in production about ± 2,000 BOPD and return the production line to original size. Launch many 8” pigs and received successfully
Challenge
- SAPESCO rigged up its equipment in the onshore process area, saving the cost of barge and logistics overhead expenses.
- Continuous precipitation of caso4 caused partial plugging of the pipeline; this created a back pressure on the production wells and has decreased the productivity. Problem solution is a great challenge.
Solution
- SAG-01 formula, one of SCS innovative solutions, can achieve
- high dissolution capacity upon calcium sulfate scale.
- SAG-01 was tested and applied through an effective treatment strategy to remove the scale efficiently; the program was taking into consideration the nature of the Scale
- SAG-01 is a powerful scale dissolver than other dissolvers.
- SAG-01 solution is considered to be an innovation & new Scale dissolver solution for the hard scale especially the calcium sulphate scale.
Results
SAG-01 was used effectively to remove the scale that resulted in significant increase in oil production and the job results were outstanding as follows:
- Production increased by about 2,000 BOPD.
- Launcher pressure dropped by about 350 psi.
- Producing wells’ backpressure decreased.
- Efficient cost /bbl.
Conclusion
- SAG-01 is a Strong & powerful chelating dissolver used for the hardness calcium sulfate scale.
- SAG-01 recorded an outstanding results and return the production to its original level.
