Natural gas storage in the South Kavala Field; geological and seismological characteristics

The South Kavala Field will have produced 670 x 10 6 Sm 3 of its original recoverable gas reserves of 1.0 x 10 9 Sm 3 by the end of 1994. Gas storage of imported gas is planned, and to provide continuity of supply and to reduce the risk of induced seismicity caused by pressure variation in the reservoir, the remaining 300 x 10 6 Sm 3 will be used as a cushion. the field lies nearby seismically active areas so the seismic hazard is evaluated. Even though the seismicity of the area is low, it is considered prudent to install a dense network of seismographs in order to monitor the effects of small magnitude (M s < or = 2.5) earthquakes.
