Reservoir management is crucial in the oil and gas industry as it involves analyzing and interpreting data to maximize oil and gas recovery. To achieve this, companies use various technologies, including wellbore imaging. In recent years, wellbore imaging technologies have evolved, providing real-time insights into reservoirs, and thus, transforming reservoir management. In this article, we will discuss the latest wellbore imaging technologies that are transforming reservoir management.
In the past, wellbore imaging technologies were used to identify the location of the reservoir, its orientation, and its properties. However, with recent advancements, wellbore imaging technologies can now provide more detailed information on the reservoir.
