If your company requires technical accuracy and in-depth analysis of geological formations, hiring an independent petrophysical consultant can make all the difference. At JACZ, Javier Carrero offers you over 20 years of international experience in applied petrophysics, combining advanced knowledge with cutting-edge tools to optimize hydrocarbon exploration and production.
Thorough evaluation of rock and fluid properties in the subsurface is key to reducing geological uncertainty. That’s why we work with integrated workflows that accurately and strategically characterize conventional, unconventional, and fractured carbonate reservoirs.
A petrophysical consultant does more than just process well logs. Their role is essential in turning raw data into strategic decisions aimed at maximizing exploration return on investment.
We evaluate porosity, saturation, permeability, and mineralogy using conventional, advanced, and image logs. We model various scenarios to reliably predict reservoir productivity.
We analyze the internal structure of formations, identifying textures, fracture orientations, and pore system alignments—key elements in assessing complex reservoirs.
We design custom workflows based on the geological setting, connecting petrophysical data with seismic attributes, stratigraphic correlations, and 3D geological models.
Hiring a freelance consultant not only offers greater flexibility, but also ensures more direct, personalized attention aligned with the project’s technical and business goals.
• Specific Technical Know-How: Over 50 projects executed in basins across the Americas, Africa, and Europe.
• Specialized Software Expertise: Proficient in tools such as Geolog, Qi Pro, PowerLog, Seisnetics, and SMT Kingdom.
• Adaptability to Global Teams: Experienced in integrating data and collaborating with geologists, geophysicists, and reservoir engineers.
• Remote and Custom Consulting: Total geographical independence and flexibility to work with operators or service companies.
From basic studies to complete reservoir characterizations, the service adapts to the technical context and required level of detail.
• Interpretation of electric, sonic, gamma, and NMR logs.
• Electrofacies generation.
• Evaluation of clay-rich, carbonate, and siliciclastic formations.
• Saturation calculations using dual models.
• Integration with core logs and laboratory data.
Each project begins with a technical diagnosis to design the optimal workflow based on your business goals.
An external consultant offers a fresh perspective, international experience, and greater independence to provide impartial diagnostics.
