... ultradeep holes by generating high‑powered microwaves at the drilling site. The microwaves will be transmitted downhole to make hole by melting and vaporizing the basement rock. The only downhole equipment is a long tube to guide the waves to their target. It is one of those ideas where the first reaction...

..., with the slope of the curve flattening. As the curve flattens, actual cost of the well versus the AFE starts to diverge as well. In many cases this flattening of the curve is a direct result of fighting mud losses, stuck pipe, or any of a myriad of other issues that prevent rigs from making hole...
