No. An analysis of historical regulatory records consistently demonstrates that well classification involved considerably more than a single gas-oil ratio (GOR) calculation. Across archived correspondence, regulator interpretations and historical guidance documents, well classification decisions repeatedly considered production history, fluid characteristics, production behaviour and the overall technical context of the well. While GOR remained an important consideration, the archive consistently shows that it was evaluated alongside other engineering and regulatory factors. These recurring findings illustrate that well classification has historically been a technical and regulatory evaluation, requiring professional judgment rather than reliance on a single numerical threshold.
