Buenos Aires, Argentina (May 3rd, 2023) - Pan American Energy, the operator, has recently successfully completed the drilling of a horizontal well in the Lindero Atravesado area in Vaca Muerta.
The 3,050-meter lateral section well was landed and geosteered with exceptional precision within a very narrow interval within the Vaca Muerta Formation, utilizing only 3.2 vertical meters of thickness to position the entire horizontal section.
The high-precision geosteering of this well was carried out by PAE's drilling and geology team in conjunction with ROGII Latina's well placement team.
PAE utilizes specialized software combined with collaborative cloud-based technology developed by ROGII to enable 24/7 monitoring, real-time interpretation, and decision-making, supporting effective and timely communication among the specialist teams. In the geological context, the lateral section was drilled along an upward-dipping monocline, ranging from 2.1° to 4.7°, crossing lithology that varied from marls to clayey limestones. Detailed analysis shows that this well achieved 76.2% (over 2,300m) within a mere 1m thickness of the target.
This project is considered a significant milestone due to the ability to meet the proposed objectives set by both drilling and geosciences.
The precise placement of the well, while maintaining a high penetration rate (averaging 45m/hour) using a BHA equipped with RSS, allowed the drilling to be completed within the planned timeline.
