CASPIAN SEA EXPLORATION BLOCKS

In south of Caspian sea, 10,000 Km. 2D Seismic lines has been acquired by Shell, Lasmo and Veba Oel Consortium during 1998- 2000.

46 Structures has been identified which 8 of them (6.2, 29, 6.1, 8.1, 7.1, N10, N9 and N3) have the priority

4000 Km2 3D Seismic has been acquired in 6, 7,8 and 29 Blocks during 2003-2005

Blocks 24,26 and 29 have been introduced now.

SARDAR-E-JANGAL FIELD

Location of sardar-e-jangal field

Sardar-E-Jangal field in block 6 is located about 250 Km. of Caspian Sea coastline, in 750 m water depth.

It is expected the main prospect is Cheleken. Although the first exploration well in 2012 has discovered hydrocarbon in layers above Cheleken.

The second exploration has been completed in 2015.

The field dimensions are about 24km x 6km.
