Kashagan Field is located in the Kazakh sector of the North Caspian Sea and is one of the largest oil<br>discoveries made anywhere in the world in the last decade. It is one of a group of isolated carbonate<br>build-ups in the North Caspian Basin. Kashagan consists of two separate carbonate platforms<br>separated by a narrow connection (Figure 1). The field is approximately 70 kilometres long and<br>ranges between 5 and 20 kilometres wide. The field was discovered in 2000 by AGIP with an<br>exploration well penetrating mainly shallow marine carbonate facies. The field is overpressured and<br>contains light oil with approximately 15% H2S. It is estimated to contain approximately 30 GBO inplace<br>and poses significant development challenges.
