Petrophysics
Petrophysics is the study of physical and chemical properties of rocks and their contained fluids (like oil, gas, and water). It's a crucial field in oil and gas exploration that helps companies understand if a well will be productive before investing in drilling. Think of it like a doctor examining a patient using various tests - petrophysicists use special tools and measurements to understand what's happening deep underground in rock formations. This information helps companies decide where to drill and how much oil or gas they might find.

Example Interview Questions
Senior Level Questions
Q: How would you approach evaluating a challenging reservoir with complex mineralogy?
Expected Answer: A senior petrophysicist should discuss their systematic approach to analyzing difficult formations, including using multiple data sources, cross-validation of results, and experience with similar scenarios from past projects.
Q: Describe a time when your petrophysical analysis saved significant costs for a project.
Expected Answer: Should demonstrate ability to make high-impact business decisions using technical analysis, showing how their expertise directly influenced drilling or development decisions.
Mid Level Questions
Q: What methods do you use to quality control well log data?
Expected Answer: Should explain basic data validation processes, common correction methods, and how they ensure data reliability before interpretation.
Q: How do you integrate core data with well log analysis?
Expected Answer: Should describe the process of calibrating log data with physical rock samples, showing understanding of both data types and their relationships.
Junior Level Questions
Q: What are the basic well logs you work with and what do they measure?
Expected Answer: Should be able to describe common well logs like gamma ray, resistivity, and density logs in simple terms and explain what they measure in the rock.
Q: How do you calculate basic reservoir properties from well logs?
Expected Answer: Should demonstrate understanding of fundamental calculations for porosity, water saturation, and other basic reservoir properties.
