DOUBLE HYDROPHILIC BLOCK COPOLYMER ON PARTICULATE SURFACE IN WELLS TO REDUCE SCALE.

摘要

Methods or systems of protecting against scale formation in a well. The methods or systems include: coating a coating material onto the surface of a particulate, wherein the coating material includes a double hydrophilic block copolymer; and contacting a fluid comprising scale-forming ions with the particulate. The coated particulate can be positioned in the well or a well servicing fluid can be flowed through the coated particulate prior to introducing the fluid into the well.
