The principal reason for waterflooding an oil reservoir is to increase production rate and, ultimately, oil recovery. Water flooding is the practice of pumping (injecting) water into selected wells in an oil field, in order to sweep the remaining oil from the rock formation and push it towards producing wells were it can be pumped to the surface.
Waterflooding is the most commonly used secondary oil recovery method as water is inexpensive, readily available in large volumes and very effective at substantially increasing oil recovery.
Typically (but not always) waterflooding is initiated some time after a field has been significantly depleted under the primary production phase. Water for this type of Enhanced Oil Recovery must be treated before and after use. This package could include any or all of the water flood products built by EN-FAB, Inc.
EN-FAB, Inc. has been in the Steam Flood business for over thirty years, and has designed and fabricated water treatment equipment using river, water, sea, produced, and well water for high pressure steam generators. It was a logical step to move into the water flood business where similar equipment is also used.
Seawater Water Feed
Typically such a system will consist of a Coarse Filter (to remove debris), a Deep Bed Multimedia Filter (to remove suspended solids), Disposable Cartridge Filters (to remove particles above a certain micron size e.g. 1-2 microns), a Vacuum Tower (to remove dissolved gases, particularly oxygen), Chemical feeds, such as polyelectrolytes for coagulation (for the filters), chlorine to kill bugs etc. in the water, scale inhibitor to prevent scaling, corrosion inhibitor to prevent corrosion, etc.
Generally the system will consist of Separators, (to remove the bulk of suspended solids), Gas Flotation units (to remove oil to an acceptable level for filtration), Multimedia Filters (to remove remaining suspended solids to about 2 ppm), Cartridge Filters (to remove particles larger than 2 microns), Vacuum Towers to remove dissolved gases, particularly oxygen), Chemical Feeds, etc.
River Water Feed
This system generally consists of a Clarifier, Multimedia Filter, Cartridge Filters for removing particles 2 microns and larger, Chemical Feeds, etc. EN-FAB, Inc. engineering staff is capable to design the entire water flood system from the customer specifications.
