Extraction of heavy oil often involves the production of steam for injection into the formation (steam flooding,
cyclic steam, SAGD). In order to minimize or eliminate the consumption of fresh water to feed steam generators,
produced water (the water which comes to the surface along with the oil) is often treated and conditioned to a
quality suitable for feed to a steam generator.
Once-through-steam-generators (OTSG) can generally be fed produced water which has been filtered and softened.
In some cases, initial treatment for silica is also employed.
Problem
Produced water filtration and softening systems which have been used over the past several years often encounter various problems such as:
• Poor Filtration Quality
• High chemical (salt, acid, caustic) consumption
• Safety concerns and costs related to handling hydrochloric acid and caustic
• Large waste volumes produced during regeneration require disposal.
• Large equipment which requires considerable space and site assembly.
Solution
Eco-Tec’s Spectrum Micro-Media Filtration
Greatly improves the quality of filtered produced water to eliminate many of the problems related to softener
fouling.
