Overview
We’re hiring an Operations Administrator to support drilling and workover operations across multiple locations. This role partners closely with engineers and field/consultant teams to ensure accurate cost tracking, invoice validation, and financial reporting across multiple systems.
What you’ll do (key responsibilities)
- Review and validate vendor invoices: confirm pricing, coding, and backup documentation match billing.
- Verify charges align to agreed MSAs/price books/bids and project requirements.
- Reject/route back discrepancies (coding, pricing, missing backup tickets, etc.) to AP and/or vendors for correction.
- Enter and reconcile cost data as invoices are approved (including entry into WellView).
- Partner with engineers to confirm services/goods belong to the correct work scope and ensure all related costs are captured.
- Track water tickets in an Excel tracker to prevent overcharges and duplicate billing.
- Coordinate with consultants/vendors to resolve missing data/signatures and validate costs not reflected in WellView.
- Support cost control activities such as invoice tracking, PO/change order tracking, budget vs. actuals, forecasting, and variance reporting.
- Help respond to internal inquiries related to open/closed invoices, audits, and vendor cost questions.
- Prepare audit support and request refunds/credit memos for overpayments/duplicate charges.
- Assist with employee expense reports in Concur.
- Conduct research, compile data, and produce basic reporting/statistical summaries.
- Maintain workflow target of keeping the invoice queue in Ariba under 100 on a running basis.
- Travel to field locations/vendor offices as needed (occasional).
Required qualifications (must-haves)
- Hands-on experience with invoice review/processing, including discrepancy resolution and documentation validation.
- Comfort working across multiple systems and spreadsheets; strong Excel skills for tracking and reconciliation.
- Strong attention to detail and ability to manage multiple priorities with minimal supervision.
- Ability to partner with engineers/operations teams and communicate clearly with vendors and internal stakeholders.
Preferred qualifications
- Ariba experience strongly preferred (candidates with strong similar-system experience such as SAP will be considered).
- Associate degree in business/technical field (or equivalent experience).
- Experience supporting drilling/workover or familiarity with oilfield terminology/well construction (preferred).
- Cost control exposure (POs, change orders, forecasting, accruals, variance reporting).
- Exposure to data visualization tools such as Power BI or Spotfire (nice to have).
