The Project Screening Model for Natural Gas Projects: Focusing on The Gas Field Development

摘要

Despite the large demand for Natural Gas (NG) that is needed to produce clean energy and resource sufficiency, entry of NG related construction market is limited by the inherent risks. Especially, the early stage of projects such as planning or feasibility study is more crucial on the uncertainty perspective than other following stage such as engineering or construction. Thus, it is necessary to implement a project screening model in the early stage of a project. This study proposes a project screening model for gas plants that incorporates two analysis aspects: market environment analysis and gas field analysis. Market environment analysis evaluates a country's political stability and the stability of the project from the market perspective. Gas field analysis evaluates technical property, participant stability, and the stability of the target project from the project perspective. Finally, a case analysis is performed using the gas field project in South Africa. The case analysis uses documents of actual gas field development and interviews with site managers. Thus, the gas field site manager validated the proposed model and confirmed its usability. When a user integrates the own expertise and experiences with this model, the model will be able to support reasonable decisions.
