Paper: Basic Principles and Value of Electric and Radioactivity Log Interpretation

Where shall we drill? Is there oil in this zone? What is the best place to perforate? Where can we find water for this flood? From where is this water coming? How much oil is there in this zone? Where is the best place to inject? Did we pass up some good reserves? Why is the gas to oil ratio increasing? The answers to these common questions result in decisions which both cost and make money. Proper use of electric logs can help solve these problems many times. For this reason production personnel should be familiar with the principles of log interpretation.
