• Exposure to different technical groups across the company.
• Technical and software training.

About the Role

The Production Allocation Engineering Intern will support the daily and monthly processes used to track, validate, allocate, and report oil, gas, and water production across the asset. This role provides handson exposure to the full productionvolume lifecycle-from wellhead measurement through gathering systems and facility balances to final sales reporting.

The intern will work closely with Production Engineers, Field Operations, Measurement, and Production Accounting to ensure production data is accurate, timely, and aligned with operational realities in the field.

This is an excellent opportunity for an engineering student interested in production engineering, operations optimization, petroleum engineering data workflows, or production accounting systems in the upstream oil & gas industry.

What the Intern Will Learn

• How volumes move from the wellhead to sales and how allocation ties the two together.
• The relationship between allocation engineering,production engineering, measurement, operations, and accounting.
• Production reconciliation, facility balancing, and troubleshooting data discrepancies.
• How allocation accuracy impacts financial reporting, regulatory filings, and engineering analysis.
• Handson exposure to real operational challenges in a producing asset.

Key Responsibilities

Daily + Monthly Allocation Support

• Assist with daily welllevel production allocation for oil, gas, and water volumes.
• Support monthly close activities, including comparing allocated volumes to tank strapping, meter readings, SCADA data, and production accounting system totals.
• Help identify and reconcile discrepancies in production data (e.g., well tests, theoretical to allocated analysis, tank measurement errors, facility imbalances).
• Validate PVT data and assist in generating updated well test inputs for allocation engines.

Data Quality & Systems

• Update and maintain production data in allocation systems (e.g., Energy Components, ProCount, Avocet, Aries, TOW, P2 Merrick, or internal equivalents).
• Review facility balancing issues and support corrections to allow monthly allocation to close.
• Assist in building or improving Power BI dashboards for visualization of production trends or allocation accuracy.
• Help maintain allocation network diagrams (well facility battery sales point).

Operations & Engineering Support

• Work with Allocation Engineers to monitor performance trends, identify unusual production behavior, or flag potential well or facility issues.
• Support analysis on flaring, venting, downtime coding, and production loss categorization.
• Collaborate with Measurement and Field Operations to verify meter performance, test separator data, tank gauging, and equipment limits.

Special Projects (depending on timing and asset needs)

• Assist with creating or updating Standard Operating Procedures (SOPs) related to allocation and production data workflows.
• Participate in allocation model improvements (e.g., new well setups, route modeling, facility optimization).
• Help support regulatory reporting inputs (state production reporting, environmental volumes, emissionsrelated data).

Required Qualifications

• Fully authorized to work for any employer in the US without sponsorship now or in the future. Additionally, we are not authorized for employment under OPT/CPT/F1 visa programs.
• Currently pursuing a Bachelor's degree in Petroleum Engineering, Chemical Engineering, Mechanical Engineering, Data Engineering, or a related technical field.
• Students with an expected graduation 2028-2029 are encouraged to apply (juniors or sophomores). May 2027 graduates may only be considered if enrolled in a post-graduate program.
• Must have cumulative and major GPA of 3.3 or higher, to be confirmed with transcript (unofficial transcript is acceptable)
• Must be available for a continuous 12-week period for the duration of the 2027 summer intern program, starting May 17th and ending on August 6th.

Technical Skills

• Strong analytical and problemsolving abilities.
• Proficiency with Excel (pivot tables, lookups, basic analytics).
• Familiarity with production systems, SCADA, or engineering software is a plus (Spotfire, Power BI, Energy Components, ProCount, Avocet, Merrick, Aries, or similar).
• Basic understanding of oil & gas production operations preferred.

Soft Skills

• Strong attention to detail and data accuracy.
• Ability to communicate effectively with engineers, field personnel, and accounting teams.
• Selfdriven and able to work both independently and collaboratively.

Internship Details:

• Position will be based out of our office in The Woodlands, TX. Interns are expected onsite Monday-Friday, with the exception of 9/80's. The 9/80 schedule is optional per the manager's discretion, based on intern project scope and timeline.
• Non-local candidates may be considered but must arrange their own travel and temporary accommodations. A summer stipend will be provided to help offset out of pocket expenses.
• Students must be available for the full duration of the internship from May 17-Aug 6. Any personal time off must be approved by the supervisor as unpaid leave and should be noted with the recruiter as early as possible.
• Interns will receive an hourly wage but are not eligible for benefits or paid time off. Interns will be compensated for observed company holidays.
