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 adding a crosslinker to a polymer solutions used as a fracturing fluid in a hydraulic fracturing operation, comprising the steps of:
- affixing a crosslinking agent to uncoated or resin coated particulates utilized as proppants in said hydraulic fracturing operation;
- placing said particulates affixed with said crosslinking agent in said fracturing fluid to function as said proppants and to add said crosslinking agent;
- and
- conveying said fracturing fluid into a formation to perform said hydraulic fracturing operation.
A method of adding a crosslinker to a polymer solution used as a gravel conveyance fluid in a gravel-packed well completion, comprising the steps of:
- affixing a crosslinking agent to uncoated or resin coated particulates utilized as gravel in said gravel-packed well completion;
- placing said particulates affixed with said crosslinking agent in said gravel conveyance fluid to function as said gravel and to add said crosslinking agent;
- and
- conveying said gravel conveyance fluid into a wellbore to perform said gravel-packed well completion.
