Abstract:
The Gulf of Thailand (GOT) Drilling Evolution represents a remarkable journey in the region's petroleum industry, significantly contributing to Thailand's long-term energy security and economic resilience. Over the past four decades, the evolution of drilling practices in the rift basin has not only expanded field life but also increased recoverable reserves. This progress has been driven by continuous performance improvement, innovation, and effective problem solving through strategic planning, collaboration, and cost reduction.
Cross-functional teamwork has played a crucial role in this evolution, enabling the drilling of more wells at lower costs. This has boosted both proven (1P) and probable (2P) reserves, even in geologically complex environments. The adoption of Slimhole drilling and advanced technologies has accelerated well production, improved data integration, and increased recoverable reserves while reducing operational costs.
Optimized project management in multi-well planning and execution has further contributed to this success. By reducing wellhead platform costs, enhancing well design, and promoting operational efficiency through batch drilling and slot recovery, the industry has achieved significant milestones. Collaboration with business partners to customize equipment and services has improved operational capabilities, while robust in-house training programs have fostered individual competency and sustainable practices.
Ultimately, the GOT Drilling Evolution is poised to substantially increase the production of gas, condensate, and crude oil. This ensures a reliable and affordable national energy supply and effectively manages the volatility associated with imported LNG prices. As gas continues to serve as the transition fuel, the GOT Drilling Evolution not only sustains Thailand’s growth but also can be modernized to pioneer the path toward Net Zero — Integrating Carbon Capture and Storage (CCS), Hydrogen Production, and Enhanced Geothermal Systems (EGS) using existing gas infrastructure.
