History
- 1971 - Ashtart field was discovered
- 1974 - Ashtart field entered operation
- 1976 - Water injection was introduced
- 1997 - Arco acquired 50% share in the field from ENI
Geology
- The Ashtart field consists of a single reservoir about 70 meters in thickness. The reservoir is heavily faulted; hence the production wells are practically non-interacting. The hydrocarbons are under-saturated, with downhole pressures in the range of 200 bars (eastern part of the reservoir) to 250 bars (western part of the reservoir), and temperatures of 140ºC. Most of the wells are at a substantial depth of ~3000 meters, and the Tubing Head Pressures (THP) are consequently low at ranging from 8 -10 bars.
