Texas-based Sentry Energy Production, LLC, is a leader in oil exploration. To ensure that Sentry Energy Production, LLC, maximizes the efficiency of previously developed oil wells, the company uses enhanced oil-recovery technology to test wells across the nation that have been deemed to be dry.
Oil formations or reservoirs can be found all over the world. However, the top oil-producing countries are Russia, Saudi Arabia, Iran, China, and the United States. In the United States, Texas and Alaska are among the most abundant producers, with California, Louisiana, and Oklahoma following close behind. Despite being a leader in oil production, the United States continues to struggle to obtain enough petroleum to meet the high domestic demand. This is due in large part to the fact that oil is not only used as an energy source to power transportation vehicles but as a component used in manufacturing other products, such as synthetic rubber and household products.
To find as much oil as possible in the United States, scientists and oil exploration experts use various high-technology tools. Geophones are one such tool. They measure sound waves traveling through rocks. The speed or blockages of the sound waves provide insight into the presence of oil-bearing rocks. Similarly, electrical currents can be used for the same purpose. The overall goal is to accurately locate enough oil-saturated structures to justify a costly drilling expedition.
