Steam drive Definition
A method of improved recovery in which steam is injected into a reservoir through injection wells and driven toward production wells. the steam reduces the viscosity of crude off, causing it to flow more freely. the heat vaporizes lighter hydrocarbons; as they move ahead of the steam, they cool and condense into liquids that dissolve and displace crude oil the steam provides additional gas drive. this method is used to recover viscous oils. also called continuous steam injection or steam flooding.

Waterflooding
1. a method of improved recovery in which water is injected into a reservoir to remove additional quantities of oil that have been left behind after primary recovery. waterflooding usually involves the injection of water through wells specially set up for water injection and the removal of water and oil from production wells drilled adjacent...

Micellar-polymer flooding
A method of improved oil recovery in which chemicals dissolved in water are pumped into a reservoir through injection wells to mobilize off left behind after primary or secondary recovery and to move it toward production wells. the chemical solution includes surfactants or surfactant-forming chemicals that reduce the interfacial and capillary forces between oil and...
Miscible gas drive
Injection of a large volume of gas from an injection well where the gas is designed to lower the viscosity of the oil and help displace it towards the wellbore....
