Leverage increased abrasion resistance, higher DLS for tighter curves, and better directional control while lowering emissions.

13—Climate action.
The Quintuco and Vaca Muerta Formations of the Neuquén Basin are characterized by highly interbedded, fractured rock and high reservoir pressure, which can lead to severe shock and vibration while drilling. These conditions can reduce drilling performance and directional control.
Wells in this area of the Neuquén Basin are typically drilled with a mud motor to achieve the DLS required to reach TD.
For challenging applications, the PowerDrive Orbit G2 motorized RSS delivers higher DLS, enabling longer runs with improved directional control. A strategy was developed for drilling the 6 1/8-in curve section using this RSS with 5°/30-m DLS and then continue drilling the lateral for 2,500 m.
The PowerDrive Orbit G2 RSS reduced shock and vibration by 92%, and the hold inclination and azimuth mode improved directional control to geosteer the well for a 100% footage in the pay zone while reducing tortuosity. The operator saved 2.5 drilling days in the curve, achieving up to 7.1°/30-m DLS, and drilled the longest lateral—3,025 m—in the Neuquén Basin for a 6 1/8-in hole section.
