Proppants

A proppant particle 1 comprises a proppant core 2 (which may be sintered ceramic or sand particle) and a resin coating 3, and the coating 3 comprises an oligonucleotide-based tracer. The oligonucleotide-based tracer may be DNA. Also shown is a method of making a proppant 1 which comprises providing...

Beschreibung
Zusammenfassung:	A proppant particle 1 comprises a proppant core 2 (which may be sintered ceramic or sand particle) and a resin coating 3, and the coating 3 comprises an oligonucleotide-based tracer. The oligonucleotide-based tracer may be DNA. Also shown is a method of making a proppant 1 which comprises providing a proppant core 2; and forming a resin coating 3 on the proppant core 2, and the method comprises providing an oligonucleotide-based tracer on the proppant. Further shown is a method of manufacturing traced proppant which comprises generating an oligonucleotide sequence of between 60 and 90 bases; checking that the sequence is unique; checking that the melting temperature is 70ºC or above; synthesising the sequence to form a tracer; and applying the tracer to proppant particles destined for a first production region.
