• Division & Region Management: Create and manage divisions and regions within your organization. Assign users and wells to specific divisions so each team only sees the data relevant to them. Useful for companies operating across multiple basins or business units.
• Role Permissions Overview: A dedicated page showing exactly what each role (Admin, Engineer, Reviewer, Advisor) can and cannot do - helpful when assigning roles to team members.
• Organization Settings: Configure your organization's name, contact details, and default preferences from one central page. Changes apply across the platform for all users in your organization.

PetroBench Platform v2

A complete rebuild of the PetroBench platform from the ground up. After over a year of dedicated development, v2 replaces the legacy system with a modern architecture designed for multi-tenant organizations, international teams, and enterprise-scale deployments.

Platform

• Modern Architecture: Completely rebuilt for faster performance, better reliability, and a smoother user experience. Pages load faster, simulations process quicker, and the entire interface feels more responsive.
• Multi-Tenant Organizations: Full organizational hierarchy with HQ, Division, Region, and User levels. Each level has isolated data access and separate branding, so a parent company can manage multiple divisions while keeping well data and user access completely separate.
• Role-Based Access Control: Granular permissions with multiple user roles including Admin, Engineer, Reviewer, and Advisor. Control who can create wells, run simulations, manage users, and access organization settings.
• Real-Time Notifications: In-app notifications for simulation completions, user invitations, and system events. No more refreshing the page to check if your simulation finished.
• Activity Logs: Track all user actions across your organization - who ran which simulation, who edited a well, who created a comparison. Filter by user, action type, or date range.

Navigation & UI

• Sidebar Navigation: New contextual sidebar replacing the legacy top navigation bar. The sidebar adapts to show relevant options based on where you are - well data tabs when viewing a well, simulation options when working on a design.
• Quick Search: Instantly find wells and simulations across your organization from any page. Start typing a well name, API number, or simulation title and results appear in real time.
• User Profiles: Full profile management with security settings, organization switching, and activity history. Users who belong to multiple organizations can switch between them without logging out.
• Welcome Tours: Guided walkthroughs for new users to get familiar with the platform. Tours highlight key features and walk through common workflows step by step.
• In-App Feedback: Report bugs or request features directly from any page without leaving PetroBench. Your feedback includes context about which page you're on and what you were doing.

Engineering Tools

• Redesigned Well Management: New well overview with status tracking, improved data entry, and the ability to edit well details inline. Wells display color-coded status badges and show who last updated them.
• Improved RodSim Workflow: Faster simulation creation with better rod data configuration. The rod input table has fewer steps to build a rod string, and simulations process noticeably faster than v1.
• Redesigned PDF Reports: Improved formatting with cleaner layouts, faster generation, and smaller file sizes. Reports include all simulation output data in a format that's easy to share with field teams.
• Rebuilt Calculators: All seven calculators redesigned with improved UI and interactive graphs. Adjust inputs and see results update in real time on the graph.
• Enhanced Comparisons: Compare up to five simulation designs side by side. Save multiple comparisons per well and export comparison data for offline review.
