An oil recovery process utilizes one or more membranes to remove silica and/or oil from produced water. In one method, the process includes separating oil from produced water and precipitating silica. The produced water having the precipitated silica is directed to a membrane, such as a ceramic membrane, which removes the precipitated silica from the produced water. In some cases, residual oil is present and is also removed by the membrane.

L'eau produite contenant la silice précipitée est dirigée vers une membrane, comme une membrane céramique, qui enlève la silice précipitée de l'eau produite.
