Formation Evaluation

Formation evaluation is the process geologists and engineers use to assess underground rock layers before drilling or extracting resources like oil and gas. It involves collecting and analyzing data from various tools and techniques—such as measuring rock porosity, permeability, and fluid content—to understand the characteristics and potential of the underground formation. This information helps determine whether the formation is suitable for extraction, ensuring safe and efficient resource recovery while minimizing risks and environmental impact. Essentially, it's like a detailed health check for underground reservoirs, guiding informed decision-making for energy development.
