Development Plan
The 21st Bidding Round
G3/57, G5/57, and G6/57 have limited data
but is required development plan.
Development concept
- Stand alone or tide in with nearby field
- Produce oil and gas at the same time or produce oil and
flare gas
- Where to sell gas
Cost
- Idea to keep cost down which is a key for petroleum
development in Gulf of Thailand
Bid winner can request available data.

- Keep cost down is key for Gulf of Thailand
Timing
Key challenge
- By the end of 4th year, there will be 50% relinquishment.
- Check seismic / AVO / Map prospects/ Drill an
exploration well / Proposed development plan
- Environmental Impact Assessments, EIA, are required for
drilling exploration wells and field development.
Make sure to have full team ready from day 1.
