Exxon turns to automated drilling in the Permian in push for higher oil output

The company installed its first automated rig, supplied by drilling contractor Helmerich & Payne, last year. It drilled two miles horizontally underground in a little over six days, the third fastest time in Exxon's history.

Exxon's use of automated rigs in the Permian and its goal of expanding the fleet has not been previously reported.

On one of Exxon's automated rigs in Midland, a gate surrounds the drilling floor with a sign reading "Red Zone: Restricted Area." A drawing of the Grim Reaper illustrates the risk that workers face around heavy equipment and pressurized systems.

Where workers would usually help move columns of drill pipe over two stories tall, robotic arms now position the pipes and connect them to a drill string. This allows drilling to continue deeper into the wellbore.

Employees on the rig communicate with Exxon's central operations team in Houston to determine the precise movements the robotic system should make.
