How do they know where to drill for oil
Assemble the oil rig. The rig is the complex of equipment containing the drills, pumps, and other machinery needed to drill the oil well. The deeper the well, the stronger the rig will need to be. Land rigs are usually trucked in pieces to the site and then assembled, while offshore wells will have the rig integrated into the oil platform. Obviously these companies want to optimize for both types of fracturing. While it is still possible to drill and produce oil in areas without optimal natural formation fracturing, it is not as lucrative, and the hydrofracking costs will be higher making these areas secondary targets for drilling.
