In the complete paper, the authors review advances in selected completions to provide insight into adoption of multilateral technology (MLT), including lessons learned and recommendations. Six demonstrative applications were reviewed to validate technical assumptions for selecting particular MLT concepts. The authors write that MLT completions can reduce between 10 and 30% of drilling and completion (D&C) cost requirements while enhancing field-development net present value (NPV) in the range of 1–21%, with the potential of promoting fields that were otherwise uneconomic. This synopsis is devoted to the authors’ proposed technoeconomic assessment of MLT.

Part 1: Economic Assessment of Dual and Trilateral Wells

A simplified performance assessment was conducted to determine the economic effect of adding multilateral wells into a particular development plan.
