1.0 INTRODUCTION 1.1 PROJECT

The Te Giac Trang (TGT or White Rhinoceros) Field is located in the northern part of Block 16-1, in the Cuu Long Basin (see Figure 1-1) some 100km southeast of Vung Tau, 20km northwest of the Bach Ho Field and 35km west of the Rang Dong Field.

Figure 1-1 TGT Field Location Map

To date, oil in the TGT field has been proven in 5 separate but geologically related accumulations of thinly bedded reservoirs.

It is proposed to develop the TGT field with at least two wellhead platforms (WHPs) H1 and H4. As the TGT reservoirs are naturally pressured and the high degree of vertical separation makes the wells prone to water break through, subsea production wells have been ruled-out because of the requirement for regular well interventions (produced water shut-offs, gas lift optimization, reservoir monitoring surveys, etc).

Figure 1-2 TGT Recommended Development Concept – Leased FPSO / H1 prior to H4

The main features of the concept are summarised below: • A 16 slot WHP located in water depth of 43.0m (LAT) over H1.1, H1.2, & H2 areas; • A 12 or 16 slot WHP located in water depth of 44.7m (LAT) and middle of the H4 and

H3N area; • The WHPs are normally unattended installations with independent power and control

systems; • Each WHP will have a Production and a Test Manifold each connected to a multi-

phase flow meter to facilitate well testing and field production allocation; • Each WHP will be designed with a Helideck offset from the Well slots to allow

Helicopter operation coincident with well intervention work. • The development will be phased with the H1-WHP installed and commissioned at

least 12 months before the H4-WHP; • There will be no processing on the WHP’s, i.e. full wellstreams transferred to the CPF; • A Central Production Facility (CPF), based on an FPSO, will be situated 2km

southeast of H1-WHP, in a water depth of 43.4m (LAT); • Oil export by shuttle tanker; • Dry gas export via pipeline tie-in to PV Gas Pipeline.

Future development of prospects and discoveries to the North (e.g. HST) will be tied back to pre-installed risers / tie-in facilities at the H1 and H4 WHPs. Possible developments are HST to the North and Voi Trang, TGD and H5 to the South and West.
