Assessment of Tertiary sequence rocks in Al-Amarah field, southeastern Iraq, using two-dimensional seismic survey data
The thesis aimed at an interpretive study of the two-dimensional seismic data in the triple sequences of the Al-Amarah oil field in the Maysan Governorate, southeastern Iraq, using (Petrel program 2019). Well data were used for peaks, formation records, and seismic data for 12 seismic lines. And preparing the structural effects using the available data for the well (Am-1) to identify and select the reflectors in the seismic section. These reflectors were at the top and bottom of the Kirkuk group formation. Time, depth, and thickness maps were made using velocity maps from the velocity model and structural image acquisition.
The structural interpretation of the upper and lower parts of the composition of the Kirkuk group shows that the composition of Kirkuk appears in the form of several structural features. The structure contains three closures, which represent two convex structures and a sinister (convex) structure extending between them in the central part of the region. Synthetic faults follow the general direction of fault movement in the (NW-SE) region. Using seismic feature techniques including (instant phase, instantaneous frequency, acoustic impedance, and alternate automatic gain control), which identified some stratigraphic features that represent stratigraphic trap in the east of the field and other phenomena such as flatspot, lenses, ( onlap), and (toplap) hydrocarbon indicators are directly detected. (DHI).
The results of the study of stratigraphic interpretation of the selected reflectors showed that the formation of the Kirkuk group (Maysan group) was deposited in the Oligocene basin during the advance of sea level. It consists of a mixture of carbonates and clastic sediments deposited in low lying (LST) and shallow marine environments. Clastic sediments (sandstones) were deposited from the progress of the laurel formation and overlapped with the carbonate shelf which was deposited as alluvial fans in the outer shelf basin (fan in slope and basin floor). It is equivalent to the Ahwaz sandy member of the lower Asmari formation, which represents the Ahwaz oil field in Iran.
The seismic reflection technique was performed on the seismic data by distributing the porosity at the level of all units of the Kirkuk group formation (top and bottom). According to the acoustic impedance analysis, it appears that the porosity decreases at the bottom of the formation with increasing porosity and decreasing (Al and density) at the top. This is due to the change in the rocky sequence or fluids present in the formation which are hydrocarbon indicators.
