Lessons learned in high-pressure high-temperature well completion in Vietnam
Abstract
Well completion operation in high-pressure and high-temperature (HPHT) conditions is a big challenge for both operators and service companies. These encompass all aspects in well construction and production operation such as drilling, completion, workover, IOR/EOR application, specialized equipment, etc. Effective risk management, cost control, deployment of skilled human resources for HPHT wells require managers and operators to approach in a way different from that used in conventional environment. The lessons learned from well completion operations in HPHT conditions, summarized from construction practices at gas fields in Nam Con Son basin offshore Vietnam, provide valuable insights and serve as a noteworthy reference for the design and execution of HPHT well completions in the future.
