6. © WesternGeco Reflection strength blob map for lines over Cheleken Ridge Lower Red Beds ? Areas of high reflectivity Good strong reflectivity north of the ridge, pinching out against the platform margins at Lower Red Bed levels. Immediately south of the ridge there are prospective princhouts against the southern bounding faults of the ridge itself Obviously there is reflectivity marked on the ridge itself, not highlighted here.

Prospectivity is within the Red Series beleive greater potential in the Miocene. A3 Easterly extension of the Erdekli structure A2 A1 A3

10. © WesternGeco Miocene ridge potential Following slides show how the Miocene has potential as shown in the existing offshore interpretation study. The slides are ordered from south to north. They show anomolous amplitudes, flatspots and rollover structures which appear to have 4 way closure. It is proposed the new seismic should define the easterly extent of the ridge by extending it further onshore and may form part of a series of en-echelon parallel ridges running north to south. These parallel ridges form drapes over the southeast thrustzone which is a product of some deep seated tectonism when the basin was compressed
