Vertical Survey Profile

The Vertical Survey Profile is one of the formations of the Field Operation Division and is distinguished by its specialized work through its formations of the only specialized crew affiliated with the Ministry of Oil concerned with surveying wells using vertical survey technology.

The crew tasks can be summarized as follows:

1. Surveying exploratory wells using Zero Offset, Far Offset, Multi For Offset technology
2. Contributing to solving geological problems facing extraction companies by applying pre-prepared programs according to a precise study to determine the stratigraphic problems of the well area and its surroundings
3. Issuing a velocity model after processing vertical surveys, which contributes significantly to improving the geological studies of the fields and guiding drilling
4. Defining the reflectors of the formations required to be studied, as it is possible to define them through the velocity survey for the well (Check Shot) and benefit from the more accurate definition of the stratigraphic and reservoir units within the formations, since the recording sampling is for every 7 metres and less
5. Coming up with the best relationship between depths and velocities of all types vertically and laterally that extend 5 km to the two sides (seismic section)
6. Obtaining secondary waves (S-Wave) with primary waves (P-Wave) which are important in studying elasticity coefficients of rocks
7. Diagnosing gas reservoirs more precisely in clastic reservoirs by studying the elasticity of rocks by the Quantitative Interpretation application
8. Determining fault and fracture systems within the seismic section during the interpretation of the vertical survey section and its integration with the seismic section passing through it
9. Improving the velocities used in processing seismic information, especially in the migration stage (Depth Migration)
10. Studying well pressures by applying the Seismic Pore Pressure technique in quantitative interpretations.
11. The Vertical Survey Crew consists of two units:
12. Well Logging Unit
13. Well Logs Maintenance Unit

Electronic Workshop:

It consists of two units:

1. Field Equipment Inspection and Operation Unit
2. Field Equipment Repair and Maintenance Unit

Repair and maintenance of field equipment of all types and repair of (LAUL - LAUX) units and repair of field units (FDU) by national hands to save hard currency and follow up on the work of recording devices in seismic crews and be present in crews when needed.
