AFE estimate & variance control

Can we produce a cited bottoms-up drill-&-complete AFE estimate, keep it current with market service costs, track in-flight estimate-at-completion, review non-op cash-call billing against WI x gross request, true up owner advances against JIB actuals, and budget-vs-actual variance across the program? Trigger phrases: afe estimate and control, afe estimate & variance control. Produces: cited afe estimate & variance control workpaper and decision flags.

Known limitations

Preview capability: useful but incomplete eval or SME coverage; human review required.
Do not use for reserve valuation or an acquisition bid. Use afe-inbox-triage for intake/authorization classification, audit-jib for post-bill charge scrutiny, and operator-capital-budget-variance for a portfolio capital-plan variance. This workflow never approves a change order, AFE supplement, cash call, refund, or JIB true-up.
