Abstract:
Developing marginal oil fields in the Gulf of Thailand presents a unique combination of geological, operational, and economic challenges. Thin reservoir sands, complex fluid behavior, and long horizontal targets demand high well placement accuracy, while congested field layouts and tight cost constraints further limit operational flexibility. These factors often make conventional development approaches suboptimal, requiring more integrated and technology-driven solutions.
This talk presents a holistic approach to transforming marginal fields into viable assets through the integration of advanced drilling technologies, real-time data acquisition, and collaborative workflows. Key technologies include Measurement While Drilling (MWD/LWD), Rotary Steerable Systems (RSS), extended reach drilling, and anti-collision techniques, all working together to enhance wellbore positioning, reduce drilling risks, and improve reservoir contact. Real-time monitoring and cross-functional collaboration enable dynamic decision-making, allowing teams to respond effectively to subsurface uncertainties during execution.
The approach is demonstrated through case studies from
Gulf of Thailand operations, highlighting how tailored solutions and integrated
workflows improve drilling performance, wellbore quality, and overall
development outcomes. Lessons learned emphasize the importance of aligning
technology with operational and economic objectives. The results show that
combining technology, data, and collaboration can significantly enhance field
development efficiency, offering a scalable framework for unlocking value in mature
and complex reservoirs.
