Increasing Infill Recovery by Drilling Extended Lateral Wells in Vaca Muerta Unconventional Reservoir

Abstract

Vaca Muerta is main UCR in Argentina and most of the concessions in country, drill horizontal wells with lateral lengths (landing point to well TD) of 2500-2800 m. Loma Campana Project developed strategy to develop complex areas by changing well architecture and methodology to drill wells with lateral lengths >4000 m. The team evaluated the feasibility of the project by generating potential well scenarios, prepared specific procedures and documentation during the Planning Phase and defined the Engineering and tools required to drill. Team executed pilot wells and immediately optimized results to massify development with new architecture.
