waterflooding

…lighter conventional crudes are often waterflooded to enhance recovery, this method is essentially ineffective for heavy crudes between 20° and 10° API gravity, and thermal recovery becomes necessary. Heavy crude oils have enough mobility that, given time, they will be producible through a well bore in response to thermal recovery…

…practiced secondary recovery method is waterflooding. After being treated to remove any material that might interfere with its movement in the reservoir, water is injected through some of the wells in an oil field. It then moves through the formation, pushing oil toward the remaining production wells. The wells to…
