ABSTRACT:
The present invention relates to resin coated particulates, the process of forming the particulates, and the particulates, utilization in petroleum well completions. More particularly, the present invention comprises the resin coated particulates and the process whereby the high strength particulate substrates are coated with a heat curable resin which is reacted with a formaldehyde source-metal compound (FS-MC) complex. The resultant resin coated particulates are less reactive or interactive with the fluids employed to convey those particulates during petroleum well completion operations.
