Oil and gas Water treatment in oil and gas production. The water used for this process is usually brine but can also be produced water from the well. Filtration is often necessary to ensure that no materials clog the well pores and needs to be treated to reduce any bacteria growth. Primary production usually only recovers 30-35% of the oil. Water injection can recover 5-50% of the oil remaining in, Well injectivity which describes the well-to-reservoir connection, is a central factor in any water injection operation. The formation characteristics, water properties, well configuration and the injection water pressure determine this. Injection well behaviour is dominated by fracture geometry if the well is operated at sufficiently high.

(PDF) Water Injection for Oil Recovery by using Reservoir. • It is the injection of water into a wellbore to push, or “drive” oil to another well where it can be produced • Recognized enhanced oil recovery technique since early 1900’s • Some oil reservoirs have natural water influx, which increases oil production – Called “water drive” reservoirs, Water injection (aka waterflooding), a form of secondary enhanced oil recovery (EOR), was first applied by oil producers in Pennsylvania in the early 1920s. In addition to restoring depleted pressure within the reservoir, it also helped transport the remaining oil to the production wells, where it could be recovered..

an advantage, but the wells are perforated high in the oil zone to delay the water breakthrough. When water breakthrough does occur the well can either be shut-down, or assisted using gas lift. Reinjection of water into the aquifer is seldom done because the injected water usually just disappears into the aquifer with no effect on aquifer pressure. 26/05/2017 · In order to slow down production decline rate and control the rising rate of water cut, it is necessary to control water injection rate.
