Amazing Precision. The following image took the Ink’s graphic design team a lot of hours in research and design to create. It is being provided to show the most comprehensive and accurate view of the drilling process to be found in print or on the web. Typical diagrams of the drilling process rarely show a scale model to accurately reflect the depths at which drillers work to reach the oil bearing Bakken shale zone. During the drilling process to the Bakken’s 10,000 foot depths, drillers will cut through dozens of layers of rock of various composition and strengths. Accurately hitting the thin Bakken layer is a technological feat. One of the most amazing aspects of this graphic is how the huge drill rig is dwarfed in size relative to the depths it operates. Truly amazing.
