1 General 1.1 Introduction

The South Belut field is an offshore development located in Block B of the Natuna Sea approximately 10 Km south of the North Belut field. The South Belut reservoir is about 10km east to west and 3 to 4 km north to south, in 102 m deep water. Four (4) commercial zones have been identified. ConocoPhillips holds a 40% working interest in the Block B PSC and acts as the operator. The development partners are INPEX with a 35% working interest and Chevron with a 25% working interest.

Figure 1-1: Location Map of South Belut Field

The South Belut field is part of Company’s Block B Development Phase 5 and upon installation it will supplement gas deliveries to the SembGas GSA-1 contract, whereas the currently producing North Belut field is dedicated to the SembGas GAS-2 contract.






Figure 1-2: Block B Development Plan

Company has completed the FEED of the South Belut Field Development Project, and a solid basis of engineering, cost-estimating and scheduling has been packaged to realise successful completion of the project via EPCI contract. The FEL 3 final concept comprises an 8 sub sea well development with the ability to add 3 future wells via a common pipe line tie back to the North Belut Central Processing Platform (NBCPP) for processing. The project requires installing new subsea wells, a subsea pipeline and umbilical, and the associated subsea and topsides infrastructure to receive, control, and measure South Belut gas on the existing NBCPP. South Belut gas and liquids shall be measured and commingled at NBCPP, and the combined production will then be exported to the existing Belanak FPSO for onward treatment and sales.
