Ande Ande Lumut

Ande Ande Lumut Oil Project Profile

The Ande Ande Lumut (AAL) oil field is located in the Northwest Natuna Sea, Indonesia, approximately 20 km from the Malaysian border and about 260 km from the nearest land (Matak, Anambas).
The field lies in shallow water with a depth of around 73 meters (236 feet).

The Ande Ande Lumut oil field was discovered in 2000 by Premier Oil through the AAL-1 exploration well.
The field has undergone several changes in ownership. Initially, it was acquired by Genting Berhad, which later sold its stake to AWE. In 2013, AWE sold a 50% stake to Santos, but as of recent developments, PT Bumi Pratiwi Hulu Energi (Prima Energi) has assumed outright ownership of the Northwest Natuna production sharing contract (PSC) that includes the AAL field.

The AAL project is estimated to contain gross proved and probable reserves of 101 million barrels of gross recoverable oil in the K-Sand reservoir and 36 million barrels of gross recoverable oil in the G-Sand reservoir, with an additional 289 million barrels of gross oil in place in the G-Sand reservoir.
The total recoverable reserves are approximately 80.45 million barrels of crude oil and condensate.
Production is expected to start in 2026, with a target production rate of 20,000 barrels of oil per day (bopd). The field is forecast to peak in production around 2028 and continue until it reaches its economic limit in 2052.

The development of the AAL oil field is planned in phases. The initial phase will involve the installation of platform jackets and the drilling of seven horizontal production wells to produce oil from both the K and G sand layers.
The production facility will use a Central Production Platform (CPP) and a Floating, Storage, and Offloading (FSO) vessel, replacing the previous concept of a Well Head Platform (WHP) and FPSO.
The wells will be connected to the CPP through flexible pipelines and cables, with electrical submersible pumps transferring the produced oil to the FSO for processing.

The AAL field is characterized by heavy oil and unconsolidated sand reservoirs, which pose significant challenges including sand production and water management. Specialized lower completion wells and long horizontal well drilling are necessary to mitigate these issues.
The project will utilize proven new technologies from other heavy oil fields to address these challenges.

PT Bumi Pratiwi Hulu Energi (Prima Energi) is the current operator of the field. Other key contractors involved include John Wood Group, Apexindo International, and NauticAWT.
Previous operators and partners have included Santos, AWE, and Genting Berhad.

The revised Plan of Development (PoD) for the AAL oil field was approved by the Ministry of Energy and Mineral Resources (ESDM) on March 5, 2024, following discussions with SKK Migas.

The development of the AAL oil field is crucial for increasing national oil production in Indonesia, contributing to the target of achieving 1 million barrels of oil production per day.
The project is expected to have significant economic benefits, despite the high operational costs due to the field's remote location and the nature of the heavy oil reserves.
