Abstract

fetched live from OpenAlex

Abstract A mature tight gas field in North Louisiana that experienced dwindling performance and erratic predictability spurred the creation of an alternative technology that boosted production rates and minimized completion costs. An average production rate uplift of 108% shown on three wells resulted from modifications to mud logging operations; careful interpretation and integration of data; and the addition of new, proprietary transforms. The resultant technology provided a variety of useful information with little or no additional cost or mechanical risk. When conventional wireline technology proved both technically and economically unsuccessful, an alternative technology was needed to determine reservoir pressure from mud log gas with sufficient resolution to support zone selection, completion design, and the identification of bypassed pay. This document describes the proprietary technology and a variety of specific applications employed by the development team. Production logs and conventional pressure measurements demonstrate the performance increases achieved by incorporating this technology into the development program.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
