TY - JOUR ID - TI - Structural interpretation of 2D seismic reflection data of the Khabour Formation in the Upper West Euphrates, western Iraq AU - Ali M. Abdullah AU - Ali M. Al-Rahim PY - 2022 VL - 63 IS - 1 SP - 191 EP - 201 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - The seismic reflection method has a primary role in petroleum exploration. Thisresearch is a structural interpretation study of the 2D seismic reflection surveycarried out in the Upper West Euphrates (Khan Al-Baghdadi area), which is locatedin the western part of Iraq, Al-Anbar governorate. The two objectives of thisresearch are to interpret Base Akkas/Top Khabour reflector and to define potentialhydrocarbon traps in the surveyed area. Based on the synthetic seismogram ofAkk_3 well near the study area, the Akkas/Top Khabour reflector was identified onthe seismic section. Also, the Silurian Akkas Hot_shale reflector was identified andfollowed up, which represents the source and seal rocks of the Paleozoic petroleumsystem in the Western Desert of Iraq. Time, velocity, depth, and isopach maps weredrawn for Base Akkas/Top Khabour reflector and showed the presence of twoanticline structures trending east-west and located on the west side of the study area.The first is termed as (A), represented by Tulul structure, and the second is termed as(B). The maps show the increase in time toward the eastern side of the study area.The general slope of the reflectors is toward the southeast of the study area, while theincrease of the thickness of the Formation is gradual to the southwest as well as thenorthwest of the study area. The study area was affected by three transversal faults.Generally, the faults have northeast-southwest trends. The Ordovician Khaboursands are the primary reservoir in the study area. They are interpreted to be presentthroughout Akkas Field as gas/condensate accumulation located 100 km to the westof the study area.
