Malaysia and Thailand are getting closer with their plans to deepen the long running energy partnership by implementing a new Production Sharing Contract and Gas Sales Agreement in Block A-18-01, Malaysia-Thailand Joint Development Area. The deals, inked in August with government authorizations in September, go beyond the current agreement’s expiration date of 2029.
The agreement’s import is that MTJDA continues to be a key source of natural gas for both nations. The Larger JDZ generates approximately 700 million SCF of gas daily, with gas split between Malaysia & Thailand.
35-Year Commitment Creates Long-Term Certainty
The new PSC and GSA are in force from 1st January 2026 and will last a period of 35 years. The contract area includes the additional land area, and original Block A-18, resulting in a more long-term contract for further exploration, development and production.
PTTEP and PETRONAS linked PC JDA own 50 per cent participation in the new block. This common layout ensures a long-term commitment to production and shares a sense of common ownership.
Gas Supply Supports Both Economies
The production at Block A-18-01 is about 300-400 million sc/d. The gas is delivered in equal quantities to Thailand and Malaysia for electricity generation and other use for energy.
MTJDA gas is of greater importance to Thailand for power generation in the southern region where supplies from the region covers ~4% of Thailand’s total natural gas demand. The setup, thus, results with direct impacts on regional electricity security.
Modern Terms Could Attract New Investment
The reworked structure also symbolises the evolving economics of offshore energy. Changes to the contractual arrangements are being made to deliver improved investment security whilst ensuring future growth remains flexible to changing energy market conditions.
More exploration territory is significant since it is the additional investment needed to sustain long term output, rather than extending output.
Next Step Could Be Block B-17-01
The A-18-01 deal may also serve as a momentum to the next level of collaboration. The officials have determined that improvement work on A-18-01 is a stepping stone to further contractual work on Block B-17-01.
That would strengthen the MTJDA as a viable model of resource development across the border without having to agree on a common energy policy, whereby Malaysia and Thailand could work together with the offshore resources.

Why Does the Deal Matters for ASEAN?
The deal comes as Asian economies aim to increase energy-security resilience amid the volatile global markets. Malaysia and Thailand are not relying on 100% imported LNG supplies, but taking steps to find a local regional LNG supply, with an existing bilateral agreement in place.
The take-home message is that Southeast Asia’s energy transition will not take place overnight and eradicate natural gas. Rather, countries can increase their supply and levels of renewable power and boost their grids’ capacity and cleaner technologies while having stability from reliable gas supply.
It is therefore more than an offshore contract with the new MTJDA agreement. It testifies to the effectiveness of bilateral cooperation in building energy security, investment confidence and regional resilience.
