H2Ocean Spectrum - Low Salinity Injection Packages
Changes the wettability characteristics of the reservoir rock, shifting the properties of a reservoir and increasing oil recovery. Low Salinity water injection shifts the properties of a reservoir to a state of water wetness, increasing microscopic sweep efficiency and consequently, increasing oil recovery. Low salinity water also provides sulphate-free water, thereby reducing souring potential and preventing scaling as it increases oil recovery. Water Standard’s low salinity packages use compact membrane technologies to optimize the design for offshore and onshore applications.
Step 1
Polar molecules in oil are attracted to the negatively charged clay surface. Divalent cations (calcium, magnesium) act as bridges between negatively charged molecules in the oil and the negatively charged clay surface.
The low salinity water breaks the oil-wet-bond, by replacing the divalent cations with monovalent cations, resulting in the release of oil from the rock surface.
When low salinity water is injected, the ion exchange equilibrium changes and bound oil becomes mobile, resulting in increased oil recovery.
Water Standard recommends compact membrane technologies for filtration, desalination and deaeration in order to compress overall footprint and weight demands and ensure high injectivity and low maintenance through the facility life.
Our compact design saves 5-20% space and weight; it can eliminate injector booster pumps, and with our optional MDA Torrnado™ technology, deaeration vacuum pumps can be eliminated.
The result is best in class performance.
