⚠ Participant type(s) not in COPI vocabulary
DownholeToolStringWellborePressure
Participant types are hand-authored in
copi-vocab, not produced by the pipeline.
Replace each with an existing vocab type, redirect it to a BFO / IOF-Core class in copi-iri-map.tsv,
or add it to copi-vocab.ttl first.
This entry cannot be saved as validated until then.
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
The lubricator provides a pressurised chamber above the wellhead that allows the tool string to be inserted under full well pressure; the stuffing box seals around the wire or tubing and the lower valve separates the lubricator from the wellbore during rigging up.
