PHASE 7 FACILITIES ENGINEERING 7.1.2 Types of Development Platform Options There are two options which are technically and commercially viable 1. The Fixed jacket platform and the floating production storage and offloading (FPSO) 2. A long term and fixed on site platform is preferable (Jacket Platform) 7.2.1 Facilities Design Concept The platform is planned for an unmanned facility to eliminate the need for personnel to be on rig The platform should be designed to accommodate servicing barges or vessel in the future The design is also aimed to withstand 25 years operating life with 30 years structural design life with monsoon storm condition. A remote well testing will be run on a monthly basis

PHASE 7 FACILITIES ENGINEERING Geological Data of Gelama Merah 1. Location 75 km from Labuan crude oil terminal (LCOT) and 15 to 20 km from Samarang Platform Number of wells: 6 wells consist of 5 producers and 1 vertical water injection 2.The producer consists of 1 horizontal and 4 deviated wells 7.2.2 Top Structure The Jacket Platform topside will be modularized integrated deck supporting the main production , a mezzanine deck and a helideck The deck on top of the wellhead shall have sufficient space to accommodate wireline and coiled tubing services 7.2.3 Substructure The Jacket shall be a 6-pile steel-insert structure utilizing 8 conductor slots and is to be designed 1.To withstand loading resulting from operations 2.To support facilities on the main production module on the top structure 3.To accommodate the risers, caisson and boat landing consideration the sea level depth

PHASE 7 FACILITIES ENGINEERING 7.3 Operation Facilities and Equipments The selection of production facilities is based on four main decisional 1.Transport and hydrocarbon evacuation 2.Substructure options 3.Processing facilities 4.Wellhead location 7.3.1 Wellhead Fluid flow from individual well will flow through the Xmas tree and routed to the production manifold 7.3.2 Production flowlines, Flow control and Manifold Collect production from several individual wells and direct it to Samarang Platform Direct production from a selected well to a well test facility located at each manifold site via a test header.
