Formation Evaluation is the process of assessing the properties and characteristics of geological formations, particularly in the context of oil and gas exploration. This evaluation helps determine the presence of hydrocarbons and the potential productivity of a reservoir. Techniques used include well logging, core sampling, and geophysical surveys. The data collected during formation evaluation informs decisions about drilling and production strategies. By analyzing factors such as porosity, permeability, and fluid content, geoscientists can better understand the reservoir's behavior and optimize extraction methods. This ultimately aids in maximizing resource recovery and minimizing environmental impact.
