This episode of the Oil Ground Up podcast features host Rory Johnston in conversation with Andy De La Rosa, a senior field engineer with 15 years of experience in the wireline industry. De La Rosa describes wireline as the "tip of the spear" for the fracking process, utilizing specialized trucks with miles of steel conductive cable to send perforating guns downhole to fracture rock with shaped charges. Beyond the technicalities, the guests examine the wave of industry consolidation and how independent firms like Underdog Wireline survive market downturns.
