Well Logging
Well logging is a crucial technique used in the oil and gas industry to understand what's underground in oil and gas wells. Think of it as taking detailed measurements and pictures of the rocks and fluids deep inside a well, similar to how a doctor uses X-rays to see inside a patient. The process involves lowering special tools into the well to collect data about the surrounding rock layers, helping companies decide where to find oil and gas. This information is essential for making decisions about drilling operations and understanding how much oil or gas might be available. Other names for this work include "wireline logging," "borehole logging," or "petrophysical logging."
