WIPO Patent Application WO/2023/163154

A1

The present disclosure provides a joint assembly for selectively isolating an isolation target layer in an open hole drilled into a stratum comprising a hydrocarbon-impregnated layer and the isolation target layer, and a production well manufacturing method and a gas production method that use said joint assembly. A joint assembly 110 comprises a tubular body section 111 inserted into an open hole 210 and installed in a position of passing through an isolation target layer ITL, and a light-emitting device 112 that is provided over the entire circumference of the outer peripheral portion of the body section 111 and that emits light for curing an uncured photocurable resin LCR introduced between the body section 111 and a hole wall 211 of the open hole 210.
