This article traces the development of the Chinese offshore oil industryfrom the early 1980s to 1998, with emphasis on the last ten years. Various aspects of development,including length of seismic survey lines undertaken, number of wells drilled, amount of oil discovered,amount of investments made, offshore fields developed, offshore production and revenue from oil salesare presented and analysed.Further, the article also discusses in detail the factors that contributed to the deflation of the highhopes relating to Chinese offshore production, with a final section taking a glimpse into the future.
