  "term": "Formation evaluation",
  "field": "Oil and gas",
  "definition": "The process of determining the physical and chemical properties of subsurface rock formations and their contained fluids. This involves analyzing data from well logs, core samples, and production tests to assess reservoir quality, fluid type, and hydrocarbon saturation. The goal is to quantify reservoir characteristics such as porosity, permeability, and water saturation.",
