Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact bits, originally developed nearly 30 years ago to lower the cost of geothermal drilling. Scientists recently brought the technology full circle, showing how geothermal drillers might use the original PDC technology, incorporating decades of subsequent improvements by the oil and gas industry.
