The Decisive Role of Microdispersion Formation in Improved Oil Recovery by Low-Salinity-Water Injection in Sandstone Formations

SPE Journal, 2019
Efficiency of low–salinity–water injection primarily depends on oil/brine/rock interactions. Microdispersion formation (as the dominant interfacial interaction between oil and low–salinity water) is one of the mechanisms proposed for the reported ...

Enhanced Oil Recovery Injection Waters

SPE International Oilfield and Geothermal Chemistry Symposium, 1977
A survey was made of the types of waters, chemicals, and water treatment methods used in enhanced oil recovery operations. The study indicated that numerous types of waters, chemicals, and water treatment methods are used. Chemical and biochemical reactions can occur when different types of waters are mixed or when enhanced oil recovery chemicals are ...

Optimising Water Injection Performance

Proceedings of Middle East Oil Show, 1995
ABSTRACT In recent years, major advances have been made in understanding injection well performance. In particular, the impact of fracturing, thermal stress effects and water quality are far better understood, as a result of both improved theoretical understanding and from detailed analyses of field data.
