This paper examines the uneven distribution of major hydrocarbon accumulations across Earth's sedimentary basins. Conventional petroleum geology explains hydrocarbon concentration through source rock quality, maturation history, migration pathways, reservoir conditions, trap formation, and preservation.
Those explanations remain essential. The narrower question here is whether hydrocarbon-rich basins also display regional structural concentration patterns that can be evaluated independently of individual reservoir histories.
The analysis focuses on basin geometry, clustering, depth, continuity, and the spatial relationship between hydrocarbon provinces and larger tectonic architecture. Instead of treating each basin only as a local petroleum system, the paper evaluates hydrocarbon concentration as a large-scale observable distribution.
Under the ABC Sequencing frame, resource-bearing basins are treated as structural outcomes that may preserve information about long-duration geological organization. The purpose is not to replace petroleum geology, but to examine whether basin concentration contains additional constraint information.
This paper expands the series from regional orientation into resource concentration, introducing an economically measurable geological outcome that can be compared against later basin, trench, and global extreme analyses.
This is Paper 5 in the sequence. It follows Arabian Peninsula structural orientation and introduces resource concentration as a structural distribution problem.
