Drilling optimization and use of titanum motor results in 40

摘要

This paper presents a case history of 12 re-entry short radius horizontal wells drilled in the Minas Field of Central Sumatra, Indonesia. These wells wee drilled in two packages of six wells each. The first package was drilled using an articulated motor system. With preliminary well preparation conducted by a well service rig, well designed milling/drill-in fluids, and consistent sidetrack plug procedures, the first package was drilled under budget. Improvements to both the milling procedure and the directional program resulted in a 40
