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.
Claims2
A method of hydraulically fracturing and propping a subterranean formation using proppants comprised of particulate substrates coated with a heat curable resin reacted with a formaldehyde source-metal compound (FS-MC) complex, comprising the steps of:
- fracturing said subterranean formation using a fracturing fluid;
- conveying said particulate substrates coated with said heat curable resin reacted with said FS-MC complex to said fractured formation using said fracturing fluid;
- causing the coating of said heat curable resin reacted with said FS-MC complex on said particulate substrates to fuse and cure into a permeable mass;
- and
- removing said fracturing fluid from said fractured formation, thereby leaving said permeable mass to prop said fractured formation.
A gravel-packed well completion method, wherein the gravel comprises a particulate substrate coated with a heat curable resin reacted with a formaldehyde source-metal compound (FS-MC) complex, comprising the step of placing said particulate substrates coated with said heat curable resin reacted with said FS-MC complex in the annular region of a wellbore between a hydrocarbon bearing formation and a porous wire wrapped mandrel.
