Advanced Platform Techniques for Chinese Offshore Marginal Oil Fields

Chinese offshore oil exploration and development have been carried out for more than 40 years. Until the end of 2000, the number of oil and gas fields under exploration grew up to 24. Though the reserves under exploration reached 608 Mt, it is only a part less than 50% of all the proved geological reserves. A majority of those untouched offshore oil and gas fields are marginal oil field, and there would be a momentous loss for Chinese energy industry if they were still left there unemployed. In recent years, based on the practical experience and rational research, lots of innovative techniques have been introduced into Chinese offshore oil fields to reduce the exploration cost. The author reviewed the development process of exploration in Chinese offshore marginal oil field. Several valuable techniques for advanced platform in offshore marginal oil field are also reviewed.
