The experience of application of new composition for lifting of mechanical impurities to the surface
G.M. GafarovaOne of the most effective methods against sand production is the continous addition of liquid to the hole annulus of well. For prevention of sand deposition and providing its lifting to the surface in wells with sand production, a new composition was applied. The developed composition is the concentration of SNKH-04 reagent in water. The suggested method was applied in 18 wells in Neft Dashlary Oil and Gas Development Board in 2012. As a result of injection of composition, it was managed to reduce the volume of formed sand plug, to acheieve decrease of risk of contamination of the territory.
