HFTS-1 Midland Basin Wolfcamp core-through-frac

Per-stage propped half-length, fracture count, and vertical containment from HFTS-1 through-fracture cores. Use to validate propped extent and height-growth in bounded Wolfcamp stacks.

Aggregate metrics

This dataset is published as inputs + assumptions evidence; no scored solver adapter is wired yet, so observed vs modeled metrics are not available.

Modeling assumptions

Evidence-only entry: through-fracture core observations of propped half-length, fracture count, and vertical containment published as reference inputs (no scored solver adapter wired yet).

Assumed

Propped half-length and fracture counts are core-derived observations, not inverted model outputs.
Vertical containment reported relative to the stimulated Wolfcamp bench boundaries.
Per-stage values represent published averages across the cored interval.

Out of scope

Scored observed vs modeled comparison (pending propped-extent adapter)
Natural fracture reactivation statistics and proppant-transport modeling
Stage-level pressure history matching

Scoring breakdown

Grade bands (worst-metric rollup)

A · MAPE ≤ 10%
