What is the primary purpose of wellbore logging?

The primary purpose of wellbore logging is to gather data about the geological formations encountered during drilling for better decision-making. This process involves using various tools and techniques to acquire information about properties such as porosity, permeability, lithology, fluid content, and more. Such information is crucial for understanding the subsurface environment and helps in making informed decisions regarding drilling strategies, reservoir assessment, and production planning.

By analyzing the data from wellbore logging, geologists and engineers can evaluate the viability of oil and gas reservoirs, determine the best locations for further drilling, and optimize extraction processes. It significantly contributes to reducing uncertainties related to the geological formations, leading to more efficient and effective exploration and production operations.
