The document outlines Indonesia's Gas Development Master Plan (GDMP) which aims to develop a long-term gas strategy over 50 years. It identifies key gas infrastructure needs and policy measures required. The plan involves three inter-linked tasks: 1) developing an optimal gas usage model, 2) identifying medium-term infrastructure needs, and 3) addressing barriers through capacity building. Task A focuses on developing demand and supply scenarios to model optimal gas usage. Task B examines policy issues like increasing production and developing domestic markets. The deliverables include interim reports, a draft final report, and training workshops on using the gas development model.
