Welcome!

Hi, welcome to my site! I started building it as a challenge and it soon developed into a new passion. One of many, that I hope you will see while exploring these pages.

I am an experienced Reservoir Engineer with a Master of Science in Engineering and a Master in Business Administration. I have a particular interest in management and optimisation and my goal is to maximise asset value through integration of people and data. I have 18 years experience in the fields of Oil&Gas, Hydrogeology and Environmental that I gained working in technical and leadership roles for consultant, operators and major companies over seven countries.

What I Do

Reservoir Modelling

18 years experience in reservoir and porous media flow modelling, including Oil&Gas, CCS, groundwater and contaminant diffusion. I developed models for new developments, brown fields, river-aquifer interaction, remediation of contaminated sites, hydrogeological stress and dewatering. I apply uncertainty analysis and statistical approaches to minimise the risk and maximise opportunities. I have an extensive experience in multiphase flow and compositional modelling.

Hydraulic Network Modelling

More than 15 years experience in networks and pipelines simulation, for Oil&Gas systems, production and injection, as well as water distribution systems. I created complex systems that simulated hundreds of wells, with applications to natural flow, thermal systems and artificial lift. I also worked in several projects with pumps, pumping stations and compressors.

Coding and Optimization

I develop workflows using scripts and coding in Python, Visual Basics and C++ to run optimisation loops in a mostly automated way. This allows to integrate Simulators, DataBases and Analytics tools to offer a deep problem analysis, in a fast and effective way that could not be achieved without automation. All the workflows can be applied to groundwater, network and well models. I also integrated these analysis with modern data analytics software like Spotfire.

PTA and Well Testing

I use analytical models to define reservoir extension, properties and connectivity. This allows for a better definition of resources in place, hydraulic barriers and aquifer parameters. I have esperience with Production Logging Tools (PLTs) interpretation. I also simulate PTA and Interference Tests with approximate numerical and full 3D models, and integrate the results in a close-the-loop cycle.

Leadership

I had several experiences as Team Leader in field studies, leading multidisciplinary teams of up to seven technical members. I was also company delegate for Technical Committee Meetings in complex Joint Venture Partnerships. I have good experience in stakeholders management, engaging in my projects directly with CEOs, partners, and regulatory authorities. I lead reservoir reviews and reserves update studies. I also trained and tutored tens of less experienced professionals as well as PhD candidate in many countries spreading across three continents.

Field Engineering

I love the hands-on part of my job: to be able to directly follow and coordinate activities on the field. I coordinated several single and multi well tests, as well as aquifer tests, planned and executed sampling campaigns, managed a remediation plant, and coordinated site activities and contractors. I also participated and lead daily calls for the management of remote sites.
