For over 6 years, I have held various positions in the water and wastewater treatment sector. Beyond my core expertise in wastewater treatment process design and advanced treatment steps such as filtration and media treatment design, I have also developed my skills in mechanical engineering, particularly in pipe, valve, and instrument selection, to achieve a high level of professionalism. I also design PV solar energy systems, of which I have led two projects. One of the most important factors distinguishing me from many others in the market is my meticulous approach to my work and the verifiability of my engineering studies. Instead of basing my design and technical decisions solely on experience, I verify them against ATV-DVWK/DWA, EN, DIN, ISO, ASME, ISA, and AWWA standards, as required by the project, using relevant technical literature, manufacturer datasheets, and engineering manuals.

I am a Civil Engineer with 10+ years in hydrology, hydraulics and GIS. I work across two main areas: pressure water distribution networks (EPANET) and flood and hydrological modeling (HEC-RAS, HEC-HMS), supported by strong GIS skills in QGIS, Global Mapper and AutoCAD. On the water supply side, I model distribution networks in EPANET, including DMA sectorization, pressure management, demand allocation and leakage assessment, covering everything from transmission mains to internal pump systems. On the flood and hydraulics side, I build HEC-RAS and HEC-HMS models for floodplain studies, catchment characterization, flood hydrograph construction and the hydraulic design of channels and culverts. I've also worked on FEMA-related studies in the US, including floodplain analysis and a No-Rise certification, so I'm familiar with how those reviews and submittals work. A good part of my background is in the mining sector, working on water management for tailings facilities, hydraulic structure design, and dam breach analysis to assess flood extents and risk to surrounding areas. I've delivered projects across Latin America (Argentina, Brazil, Colombia, Mexico, Chile, Nicaragua), Africa (Ghana, South Africa, Burkina Faso), the Middle East (UAE), Asia (India), Europe (Spain), the US and Australia. That range has made me comfortable adapting to different standards, data sources and project requirements. I move easily between hydraulic modeling, risk assessment and water resource management, and I'm used to integrating georeferenced data from different sources. If you tell me about your project, there's a good chance I can help. Feel free to reach out.

What does a Petroleum engineer do?

A petroleum engineer designs and oversees the technical methods used to extract oil and gas from underground reserves. This role focuses on analyzing reservoir data to maximize recovery rates while maintaining safe drilling operations. Engineers evaluate subsurface characteristics to select the most effective extraction strategies for specific geological conditions. They also monitor well performance to troubleshoot issues and adjust production approaches as needed.

  • Design wells and surface facilities to extract and produce oil and gas from underground reserves. This work involves selecting appropriate drilling methods and equipment based on the specific geological features of the site. Engineers create detailed plans that guide the construction and completion of wells to ensure they meet safety and production standards. These designs serve as the foundational blueprint for all subsequent drilling and extraction activities in the field.
  • Analyze production and reservoir data to improve oil and gas recovery rates. Engineers study subsurface information to identify trends that affect output and determine why certain wells underperform. They use this analysis to recommend changes in drilling techniques or reservoir management strategies. This continuous evaluation helps operators maintain optimal production levels and extend the useful life of the resource field.
  • Research and develop methods to recover additional oil and gas using advanced reservoir recovery approaches. This includes investigating techniques such as hydraulic fracturing or enhanced oil recovery to access resources that standard drilling cannot reach. Engineers test these methods in controlled environments before applying them to active sites. Their work ensures that extraction processes remain efficient and capable of adapting to changing reservoir conditions over time.

How to hire a Petroleum engineer on Upwork

Step 1: Post a job

Define your extraction goals and reservoir challenges clearly to attract qualified engineers. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description from a few sentences about your needs. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify whether you need well design, drilling plans, or reservoir analysis to improve recovery rates.
  • List required expertise with surface facility systems or specific well completion practices like hydraulic fracturing.
  • Clarify if the role involves troubleshooting underperformance or researching methods to combat issues like saltwater encroachment.

Step 2: Evaluate candidates

Look for portfolios that demonstrate concrete experience in oil and gas field development and production optimization. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit.

  • Review well and facility design outputs that show how candidates selected extraction methods based on subsurface characteristics.
  • Check for production and reservoir analysis results that led to measurable improvements in oil or gas recovery.
  • Verify experience with drilling equipment oversight and safety protocols during well execution phases.

Step 3: Interview your top choices

Discuss specific technical approaches to reservoir management and equipment maintenance during your conversations. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session.

  • Ask how they analyze production data to identify causes of underperformance and adjust recovery strategies.
  • Discuss their process for designing drilling plans that balance efficiency with operational safety standards.
  • Explore their experience with installing and maintaining oilfield equipment to ensure proper function.

Step 4: Agree on scope and begin work

Set clear milestones for deliverables such as drilling plans or operational recommendations to increase extracted volumes. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Define specific outputs like technical studies on recovery topics or detailed well placement strategies.
  • Establish timelines for analyzing reservoir data and submitting reports on optimal recovery methods.
  • Agree on criteria for evaluating the success of designed facilities and extraction processes.
