ABSTRACT:
The present invention relates to methods of reducing water produced with hydrocarbons from subterranean formations penetrated by well bores. The methods basically comprise the steps of coating a particulate solid material with an organic polymer which reacts with water and swells when contacted therewith whereby the flow of water through a pack of the resulting polymer coated particulate solid material is reduced or prevented, and thereafter, placing a pack of the polymer coated particulate solid material in or adjacent to the formation whereby water and hydrocarbons produced from the formation are caused to flow through the pack.
