Assistant President of Administrative affairs, Prof. Dr. Hussein Hamid Karim, chaired MA discussion committee of the student Omar Adel Omar Adel Naji Al-Taei, in the Department of Earth Sciences, College of Science - University of Baghdad, which is tagged
"Analysis of seismic data for a new sub-surface structure, northern Iraq"
The study aimed at the structural analysis of the two-dimensional reflective seismic data of a new structure in northern Iraq, within the Kirkuk governorate, and the reflectors were identified and captured on the seismic section using the seismic effect manufactured from the sensors information for a new well 1-, three main reflectors were captured, namely (Al-Fatah, Al-Jaribi, Al-Furat), which were deposited within the middle Miocene, lower Miocene, and early Miocene) respectively
Based on the structural analyzes of the captured reflectors, and the information of the new well-1, the study area was affected by two phases of tectonic forces. The first was during the Late Cretaceous, which causes aperogenic movement, while the second was during the Tertiary period, which is the alpine movement that builds mountains, so the structure will be a narrow, asymmetric longitudinal fold towards the axis of Northwest-Southeast. The structural splitting results showed the installation dome. The temporal, velocity and depth maps were drawn based on the structural interpretation of the captured reflectors
Structural closure was demonstrated.
The faults / cracks were captured during the Cretaceous period of the slope lines of the two-dimensional sections. The tensile forces led to the occurrence of the normal cracks extending from the Jurassic period, and the lower Cretaceous period to the upper Cretaceous period. The normal faults / cracks associated with the depressions within the study area were indicated towards the northwest-southeast axis, it did not appear the effect of normal faults on new structures during the Tertiary Era on seismic sections and depth maps. The torsional movement at the end of the Pliocene resulted in the formation of folds and inverse faults along the sequence and a reversal of movement along the pre-existing normal faults, resulting in a new type, inverted faults, which are represented by two opposite arrows in the direction of displacement.
The seismic inverse, which is used to convert seismic information into acoustic impedance, was applied to the seismic lines of the study area to predict areas of improvement for the reservoir properties of the formations (Al-Jaribi, Theban, and the Euphrates) using the information of the new well-1.
The results of the seismic inverse showed a decrease in the values of the acoustic impedance of the follicular reservoir, which is evidence of the high porosity of the formation, and the improvement of porosity values towards the east, north-east and south-west of the follicular reservoir.
