Key Responsibilities

Town Runs & Operational Support Duties

• Perform regular town runs for picking up supplies, chemicals, tools, spare parts, fuel, and equipment needed for field operations.
• Coordinate with local vendors, suppliers, and service providers in town (e.g., hardware stores, oilfield suppliers, welding shops, or delivery services) to arrange pickups or deliveries.
• Deliver field documents, mail, or small equipment between the field office and town locations.
• Assist with basic inventory management: track stock levels, receive deliveries in town, and transport items back to well sites or facilities as needed.
• Provide light operational support, such as dropping off or collecting field tickets, maintenance logs, or safety equipment during town runs.
• Handle miscellaneous errands, shipping runs, or transporting personnel/tools between locations.

Admin & Front-End Invoicing / Work Order Duties

• Process and manage work orders for field services, maintenance, repairs, equipment usage, or material requisitions.
• Collect field data and tickets from crews or operators, then enter and verify details for accuracy.
• Prepare and generate client invoices using billing software (IMS, SAP ect….) for completed jobs, materials supplied, labor, and services rendered.
• Handle front-end billing tasks: data entry, attaching backup files, printing/sending invoices to clients via email or mail, and tracking invoice status.
• Follow up on open work orders or billing discrepancies with field teams or vendors; resolve issues to prevent delays in invoicing.
• Support general administrative duties, including filing, scanning documents, updating spreadsheets, answering phones, and maintaining organized records of errands, purchases, and invoices.
• Assist with month-end close by reconciling town-run receipts, work orders, and invoices; flag any unbilled items or outstanding issues.

• Excellent attention to detail for accurate data entry, invoice preparation, and receipt reconciliation.
• Valid driver’s license with a clean driving record and reliable vehicle (or company vehicle provided); comfort with frequent town/field travel.
• Good communication skills for dealing with vendors, field crews, and clients.
• High school diploma or equivalent required; additional training in safety, bookkeeping, or oilfield admin preferred.

Typical Work Environment & Schedule

Primarily office-based with frequent town runs (daily or as needed) and occasional light field visits. Standard daytime hours with some flexibility for urgent errands or month-end deadlines. This role is well-suited for smaller teams where one person keeps operations running smoothly through reliable support and timely billing.

This version emphasizes the “go-to person” aspect — handling town logistics and admin while ensuring work orders turn into paid invoices without delays.
