I have stated that drilling is 80 percent knowledge and 20 percent luck. Bad luck happens when a driller encounters a loss zone, thus preventing the driller from finishing the hole.
If anyone gets around, it’s Gary Sprowls, MGWC, a drilling supervisor at Jackson Geothermal, based in Mansfield, Ohio. Sprowls oversees commercial geothermal closed loop jobs in states including, but not limited to Ohio, Missouri, Alabama, Virginia, West Virginia, Pennsylvania, New York and Kentucky.
