Intelligent Completion Enables Zonal Isolation Offshore Malaysia

As fields mature, drilling and completion design and execution for infill development become more challenging. In a deepwater environment, one strategy is to target several reservoir packages in a single wellbore. This technique frequently presents technical challenges, however, because penetrating different zones requires active reservoir management, an allowance for zonal isolation, and an adequate response to potential crossflow. The complete paper presents a completion strategy implemented in an intelligent well completed in the Malaysian deepwater Block K.

Introduction

The SNP Field is 125 km offshore Sabah in approximately 1350–1400 m water depth.
