How this pay compares

At $80/hr, this role pays more than 48% of the 207 open engineering roles with a listed pay range, the same as the median.

Among platforms with 10 or more priced engineering roles, Mercor has the highest median ($88/hr across 35 roles) and micro1 the lowest ($60/hr across 28).

OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 2 days ago.

Computed from 2,746 open roles we track across Mercor, micro1, Handshake AI, Alignerr, Appen and OpenTrain AI, refreshed daily. Midpoints of listed ranges; “up to” ceilings are left out of medians.

The work

You will help improve AI systems by reviewing subsurface and reservoir engineering content for technical quality and practical accuracy. You will also complete analytical work and data outputs using established reservoir and production workflows.

The work may include building price forecast models, preparing PPA documentation, reviewing reservoir simulations, and producing independent technical outputs with tools such as Techlog, Avocet, Petrel, or ARIES.

  • Evaluate AI-generated subsurface and reservoir engineering content.
  • Build price forecast models and develop PPA documentation in a structured format.
  • Apply reservoir simulation and production forecasting workflows.
  • Complete SEC oil and gas reserves reporting, well test analysis, and interpretation.
  • Calculate production allocation across working interest owners.
  • Produce independent analytical outputs using relevant engineering tools.

What it pays and takes

This is an ongoing, project-based contractor opportunity for professionals who can work independently on technical assignments.

  • Pay: Up to $80 per hour.
  • Location: Fully remote and open to candidates in the United States.
  • Schedule: Flexible and asynchronous, with no minimum hour requirement.
  • Typical workload: Approximately 5 to 20 hours per week during an active project.
  • Experience: At least two years in subsurface engineering, reservoir analysis, production operations, or a comparable energy-industry role.
  • Relevant backgrounds: Reservoir engineering, reservoir modeling, petrophysics, reserves engineering, petroleum production, well testing, or production allocation analysis.
  • Requirements: Ability to complete relevant reservoir and production workflows independently, strong written communication, and close attention to detail.
  • Helpful experience: SEC reporting, reservoir simulation, production forecasting, well test interpretation, production allocation, Techlog, Avocet, Petrel, or ARIES.
