URLReserves Life

Proved reserves / annual production (years) for {legal_name}. EXTRACTION RULES: Extract proved reserves AND annual production as explicit primary-filing numbers (SEC 10-K reserves table / Wood Mackenzie) and report their ratio in years. ZERO-IS-ABSENT: if either reserves OR production is missing / not broken out in a readable way, return absent (not_disclosed) — NEVER return 0 and never compute a reserves-life from a guessed/assumed denominator (a 0-year read means the reserves or production figure was not found, not a real worst-case resilience). Return exact_numerical{value: <years>}. Ratio_band (<5→25, 5-10→55, 10-15→75, 15-25→88, 25+→95).
