Manual for the Open Upstream Gas and LNG Model

This manual has been developed for training purposes. It models the gas value chain from the upstream project to the use of gas under the form of LPG, LNG or as feedstock for local industrial or power generation uses. It allows users to assess different LNG structures that can be considered when producing LNG (see section 2 for an explanation of each structure). It provides various fiscal regime options for the upstream and mid-stream sectors to understand the impacts of changes on the government take and the private sector returns.
