Target class: unconventional gas reservoir Context triple: [Marcellus Shale, instanceOf, unconventional gas reservoir]
-
A.
unconventional hydrocarbon reservoir
chosen
An unconventional hydrocarbon reservoir is a geologic formation that stores oil or gas in low-permeability rocks or complex settings requiring specialized extraction techniques beyond traditional vertical drilling.
-
B.
natural gas field
A natural gas field is a subsurface accumulation of natural gas trapped in porous rock formations, typically exploited through drilling and production infrastructure for commercial energy use.
-
C.
hydrocarbon-bearing formation
A hydrocarbon-bearing formation is a subsurface rock unit with sufficient porosity and permeability to store and transmit economically recoverable quantities of oil and/or natural gas.
-
D.
natural gas crater
A natural gas crater is a large, often circular depression in the ground formed when a pocket of natural gas ignites or collapses, sometimes burning continuously and creating a dramatic fiery landscape feature.
-
E.
hydrocarbon accumulation
Hydrocarbon accumulation is the natural concentration of oil and/or gas in a porous and permeable subsurface trap where they are retained by a sealing formation.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
