Field Development Planning with Operational and Financial Context

Build executable plans for wells, rigs, and crews. Track readiness, sequence development activity, and evaluate the impact of schedule changes on production, capital, OPEX, and cash flow. Integrates with PHDWin and ARIES.

  • Schedule wells, rigs, crews, and related activities in a shared development plan, with schedule changes recalculating dependent work and timing.
  • Track operational readiness, constraints, dependencies, and milestones so planned activity can be sequenced around field and resource availability.
  • Evaluate the production, capital, OPEX, and cash flow impact of schedule changes while keeping operational plans tied to financial context.
  • Compare development scenarios and timing alternatives before committing resources, then carry approved planning assumptions into downstream capital authorization.

Control the Complete AFE Lifecycle

Move beyond spreadsheets, email chains, and basic approval routing with a connected AFE management system that enforces your processes, keeps AFE, well, and financial data aligned across systems, and strengthens control from AFE creation through performance analysis.

  • Configure workflows, approval limits, routing rules, and supplement handling to reflect your approval structure and enforce AFE policies.
  • Create AFEs with cost estimates, economics, and supporting information, then manage revisions and track status in one system.
  • Align AFE and well data across systems by integrating with accounting, production, drilling, reservoir, and other upstream applications.
  • Monitor status, aging, milestones, exposure, and cost variance through dashboards, alerts, lookbacks, and performance reports.

  • Automate invoice capture, indexing, coding, validation, matching, exception handling, and approval routing with configurable workflows and delegation-of-authority rules.
  • Improve operator-supplier collaboration through dedicated portals for invoice submission, supporting documents, communication, dispute resolution, approvals, and invoice and payment status.
  • Link spend to AFEs, accruals, cash forecasts, field estimates, and accounting systems to keep commitments, invoices, accruals, and cash forecasts aligned through payment.
