Platform
Replace spreadsheets with a collaborative, cloud-native platform trusted by engineers.
Upload monthly production data and auto-fit exponential or hyperbolic Arps decline parameters. Fine-tune qi, Di, and b-factor with visual feedback.
Your entire team works from one source of truth. Role-based access keeps data secure while enabling real-time collaboration across offices.
Roll up forecasts across wells and leases. Compare P10/P50/P90 scenarios, track total EUR, and see aggregate economics at a glance.
Run full-cycle economics with custom price decks. Calculate NPV, IRR, payout, and cash flow projections — single wells or entire portfolios.
Create organizations, invite team members, and assign roles. Track who created forecasts, approved reports, and maintain full audit trails.
Generate reserve reports aligned with SEC and PRMS guidelines. Export PDF summaries with production charts, type curves, and economic tables.
