Target class: hydrocarbon basin Context triple: [Kutei Basin, instanceOf, hydrocarbon basin]
-
A.
geological basin
A geological basin is a large, low-lying structural depression in the Earth's crust where sediments accumulate over time, often forming significant stratigraphic and resource-bearing sequences.
-
B.
sedimentary basin
chosen
A sedimentary basin is a low-lying region of the Earth's crust where sediments accumulate over long periods, often forming thick sequences of sedimentary rocks.
-
C.
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.
-
D.
oil-producing region
An oil-producing region is a geographic area where significant quantities of crude oil are extracted, often characterized by specialized infrastructure, economic dependence on petroleum, and associated environmental and geopolitical impacts.
-
E.
unconventional hydrocarbon reservoir
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.
- 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.
