Ande-Ande Lumut (AAL) is located within the Northwest Natuna block, in shallow waters of approximately 70 meters, with reservoir depths of around 1,100 meters.

The Northwest Natuna block covers an area of approximately 461 km² and lies about 260 km (145 nautical miles) north-northwest of Matak in the Anambas Islands, 510 km northeast of Singapore and Batam, and 1,300 km north of Jakarta.

Asset details

Horizontal wells with latest technology

Coupled with the latest completion equipment (screens, ICDs etc) make this heavy oilfield fully viable.

Oilfield Ande-Ande Lumut

Development of the AAL oilfield is currently underway, with first oil targeted by 2027. A Central Production Platform (CPP) will be installed and connected via bridge-linked system to a spread-moored Floating Storage Offloading (FSO) vessel.

Synergies between Prima Energy and marine operations create a real operational experience and significant savings opportunities.

Appraisal & Development

Oilfield Appraisal

The AAL area is a seahorse-shaped accumulation, approximately 8 km N-S x 4 km E-W which divided into southern, central, and northern segments.

Four wells have delineated on this discovery: AAL-1X drilled in 2000, AAL-2XR and -3X drilled in 2006, and AAL-4X drilled in 2016.

As a result, 3 wells in the central part and 1 well in the south of the discovery have successfully been tested.

Ande-Ande Lumut (AAL) Plan of Development

A new AAL Plan of Development (PoD) was approved in 2024. This new PoD will use a Central Processing Platform (CPP) with 20 or more horizontal wells, and a Floating Storage & Offtake (FSO) vessel. Each horizontal well will utilise sand control, inflow control and electrical submersible pump; as the oil is heavy and the sand unconsolidated.

The CPP will start constructin in 2026, and first oil is expected in late 2027/2028.
