Programs that the 6th seismic crew is currently implementing First – (2D) Tabeer - Shibl program (a national effort):
The Tabeer-Shibl project is located in the southwestern part of Iraq within the administrative borders of Najaf province, its western part is about 45 km from the Iraqi-Saudi borders, and the eastern part of the project is about (85 km) from the center of Najaf province.
- The length of the program lines is (2876) km / length, and the number of program points is (115004) energy points.
- Working on the program began on 27/11/2021.
- The completed volume reached (192) km / length, and the number of recorded points was (6272) energy points.
- Working on the program stopped on 4/3/2022, and the 6TH crew moved to the participate with the 2nd crew to implement the Haifa Program and to start surveying the part allocated to the (Block 2) crew. The crew's transmission period was (29) days, with self-efforts.
Second – (2D) Haifa (Block 2) program (national effort): According to the plan of Oil Exploration Company to survey the gas blocks in western and southwestern of Iraq, and after obtaining approvals from Al-Najaf Governorate, the staff of the 6th Seismic crew was assigned to carry out seismic survey operations for the 2D Haifa project to complete surveying for this project before the planned time. Coordination has been made between the two crews by dividing the project into two parts, the 6th Seismic crew will survey the southwestern part of it, which is adjacent to the Iraqi-Saudi borders.
- The crew started the survey operations for the second part (Block-2) on 02/04/2022
- The volume of the Sixth crew, Block 2, was (1990.5) km / length, and the number of points was (39,810) points.
- The volume achieved until 31/12/2022 was about (1021) km / length, and the number of points recorded was (20445) points.
-The percentage of completion of Block 2, was (51%).
The crew was able to achieve positive implementation and achieve the annual plan issued by the Planning Division, with a completion rate of (102%) of the annual plan for 2022.
