Abstract |
: |
This study included the construction of two regional
seismic sections in southern Iraq; the first is 196 km in length and
and started from SA-1 well in southern west of Iraq, and ended at
SA-3 well, passing through SA-2 well at Basrah region. The second
regional seismic section, about 167 km in length, started at
SA-3 well near the southern boundaries of Iraq, south of Basrah
city, and passed by SA-3, SA-4 and SA-5 wells, then ended at SA-
6 well at the Amara region.
Twelve seismic reflection lines were used, in addion to some
minor seismic lines to link the major lines. Many conventional
processing tools were applied to construct the two regional sections.
One of the results of the present study is the explanation of the
general structural features along the regional sections. The results
also show the detailed structural changes on the Jurassic sediments
considered in the present study, which included Gotnia,
Najmah, Sargelu, and Alan formations.
Gotnia Formation showed a decrease in thickness between
2390-2470 CDP, which is thought to have resulted from salt and
anhydrite beds motion. Generally, it is believed that the thickness
of Jurassic sediments for the studied formations is reduced in
southern Rumaila and Halfaya due to vertical tectonic movements
which affected the structures of the southern southeastern region
of Iraq .
The boundary between the main tectonic units of Iraq (the
stable and unstable shelf) has been defined on the first regional
seismic section at 1500-2000 CDP. |
