Building on MPD’s success in Vaca Muerta (VM), this study focuses on advancements beyond drilling ahead. Key optimizations include enhanced ECD management for longer laterals, improved well control during tripping with reduced mud needs, and streamlined cementing operations. The study aims to demonstrate how MPD can significantly improve the economics and safety of ERD projects. This study employs a comparative analysis of conventional and MPD drilling methods for ERD. Limitations of conventional methods (e.g., ECD-induced losses, restricted lateral length, narrow tripping margins) are contrasted with MPD’s use of lighter fluids for lower ECDs, extended reach, and improved footage per day. This also includes the impact of MPD-optimized fluid composition on downhole tool longevity. The analysis extends to MPD-enabled stripping for BHA tripping and underbalanced well completion, for reduced flat time and improved mud volume efficiency. Furthermore, it explores managed pressure cementing (MPC), benefiting from underbalanced slurries and offline cementing, to minimize flat time and enhance cement placement. The MPD application in ERD wells results in lower ECD and BHP compared to conventional drilling and constant bottom hole pressure-MPD, increasing both surface equipment and downhole tool pressure margins. This facilitates longer drain sections while mitigating losses and wellbore breathing. MPD also compensates for swab pressures while tripping, significantly reducing tripping downtime linked to influx management. Moreover, it removes the need of full well displacement to kill mud enabling optimized mud rollover designs, minimizing ECD peaks, losses, and required mud volume. In turn, this leads to stripping operations for casing deployment with statically underbalanced mud weight, reducing surge-induced losses and enhancing gas management, thereby eliminating secondary well control requirements and associated NPT. Hence, there’s a significant impact on operational efficiency and flat time. Finally, MPC demonstrated improved cement placement and reduced lost circulation, coupled with effective gas management during the operation. Furthermore, the MPD equipment-setup facilitated offline cementing for the production section, removing the waiting on cement (WOC) time from the rig’s critical path, significantly increasing the rig’s operational efficiency. This paper presents MPD as a holistic optimization tool for ERD, beyond influx management. MPD enhances lateral length, tool longevity, tripping speed, and well control, improving ERD safety, efficiency, and economics. It introduces novel MPC applications, enabling offline cementing and lighter slurries for enhanced cement placement. The paper evaluates MPD’s transformative impact on ERD by addressing ECD challenges and streamlining well construction.
