Abstract

An oil production well comprises an upwardly dipping or substantially horizontal inflow section such that a J--or L-shaped well is created. Hot fluid, such as steam, is injected in the region of the toe of the well such that the injected hot fluid is induced to flow together with the produced crude oil into the well, thereby heating up the inflow section of the well and stimulating the flow of crude oil into and through said inflow section.
