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
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.
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.
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.
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.
