METHODS OF REDUCING WATER PRODUCED WITH HYDROCARBONS FROM WELLS

摘要

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.
