Petroleum Engineer
Designs and optimizes extraction strategies in unconventional reservoirs. Key to Vaca Muerta's expansion.
What does a Petroleum Engineer do?
- Designs completion and stimulation programs for horizontal wells in unconventional formations
- Analyzes decline curves and pressure data to adjust production forecasts for each well
- Runs reservoir simulations to compare development scenarios and well spacing options
- Builds the technical and economic case for each new well and defends it before the investment committee
- Coordinates with service companies on the execution of fracturing jobs, testing, and well interventions
- Monitors active well performance and defines remediation actions when production deviates from forecast
Ideal OCEAN+ Profile
Ability to integrate geological, engineering, and operational data to design unconventional solutions in complex reservoirs
Technical rigor in well design, reservoir simulations, and compliance with safety and environmental regulations
Coordination with cross-functional teams and ability to communicate technical findings to non-specialists
Collaborative work with geologists, operators, and contractors on projects with high technical interdependency
Stability under technical uncertainty, changing reservoir conditions, and production pressure in 24/7 operations
Well design and operation demand following standardized technical procedures, reservoir safety protocols, and defined operational sequences; improvisation in well completion has catastrophic consequences
Strengths and Red Flags
Strengths
- Reservoir modeling and production strategy optimization
- Interpretation of integrated seismic data and well logs
- Economic evaluation of drilling and completion projects
- Technical management of specialized field vendors and services
Red Flags
- Disconnect between technical models and actual field operations
- Underestimates safety risks under production-target pressure
- Difficulty communicating technical uncertainty to management without losing credibility
- Methodological rigidity when reservoir conditions deviate from expectations
What does a successful Petroleum Engineer do?
The behaviors that separate top performers from average in this role, and the OCEAN+ profile dimension that explains them.
Personally verifies the assumptions behind each simulation run before presenting it to the committee, even when the software delivers plausible results
ConscientiousnessWith Conscientiousness in this range, the profile doesn't delegate validation to the tool: they know a poorly loaded assumption becomes misallocated capital
Follows the completion program's approval sequence even when a favorable operating window tempts skipping steps
Structure & RhythmHigh Structure & Rhythm sustains process discipline precisely when the schedule pushes the other way, which is when it matters most
Reports to the committee that the well is underperforming forecast using raw data, without dressing up the curve or becoming defensive
Emotional StabilityEmotional Stability at this range lets them separate professional standing from well outcomes, and that separation is the foundation of their technical credibility
Designs small-scale pilots to test a new completion variable rather than changing the entire campaign's design at once
OpennessOpenness at this range pursues improvement through experimental control: curiosity with method, not novelty for its own sake
Incorporates field personnel's observations into the design instead of imposing the office model without discussion
AgreeablenessMedium-high Agreeableness lets field knowledge into the design, whereas more imposing profiles produce plans the field can't execute
Requirements and Skills
- Degree in Petroleum, Chemical, or Mechanical Engineering with a reservoir focus
- Prior experience in unconventional reservoirs or in completion and stimulation operations
- Proficiency with reservoir simulation and production analysis software
- Ability to build and defend drilling economic cases before non-technical audiences
- Availability for periodic site visits and joint work with operations teams
- Technical English for interacting with service companies and specialized documentation

Illustrative Example
Adapting stimulation techniques from other basins to Vaca Muerta's local context
An O&G operator uses this profile to select petroleum engineers with the openness to learn from other basins and the rigor to adapt rather than simply copy. For example: an engineer leads the review of multistage completion design across a set of horizontal wells. Their Conscientiousness lets them identify underperformance patterns in pressure and production data that others had overlooked. Their Openness leads them to incorporate stimulation techniques proven in other basins, adapted to the local formation's context. The redesigned wells show improved initial production and lower cost per barrel. This pattern illustrates that completion innovation doesn't come from new technology: it comes from engineers willing to question the baseline design.
