Breakthrough Completion by Applying Monobore Completion Well Design on SKL-XXX Well

Abstract

Since Pertamina internal reorganization, Pertamina EP Asset 5 joined within Pertamina Hulu Indonesia (PHI) group, following PHSS, PHM, and PHKT. Since long time ago, Pertamina EP Asset 5 applies conventional completion design (7 inch liner with 2-7/8 inch tubing inside) meanwhile PHSS, PHM, and PHKT already applied Monobore/dual Monobore completion design (cemented 4-1/2 inch or 3-1/2 inch tubing inside open hole) for well duration and cost optimization in their wells for years. Noticing Monobore completion design was proven for well duration and cost optimization, Pertamina EP Asset 5 adopted their success story by replicating Monobore completion design to apply in well SKL-XXX located in Zone 9 as a pilot project. From preliminary study, the application of Monobore completion design in SKL-XXX was expected to optimize cost at around of 190 KUSD and faster drilling time by 3.4 days. During project execution, trial of Monobore completion was successfully applied without major operational problem and delivered actual cost saving at around 99 KUSD and faster completion duration at around 1.6 days compared to conventional completion. This success story of trial Monobore completion at SKL-XXX has been proven as alternative for optimization improvement in the future and opens opportunity to deploy Monobore completion design in all Asset of Pertamina EP.
