TY - JOUR ID - TI - Application of the Surface- consistent DE convolution on a seismic data of Al-Najaf and Al-Muthanna Governorates in the south of Iraq AU - Kamal K. Ali AU - Laith R. Khaleefah PY - 2018 VL - 59 IS - 4C SP - 2257 EP - 2266 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - This study deals with the application of surface-consistent deconvolution to the two-dimensional seismic data applied to the Block 11 area within the administrative boundaries of Najaf and Muthanna Governorates with an area of 4822〖km〗^2, the processed seismic data of line (7Gn 21) is 54 km long. The study was conducted within the Processing Department of the Oil Exploration Company. The gap surface- consistent deconvolution was applied using best results of the parameters applied were: The length of the operator 240, the gap operator 24, the white noise 0.01%, the seismic sections of this type showed improvement with the decay of the existing complications and thus give a good continuity of the reflectors at the expense of resolution.Then, spiking surface- consistent deconvolution was applied using the best implementation parameters chosen during the test: operator length 240, gap operator 4, and added white noise 0.01%. This type gave a better estimate of reflectivity in seismic sections with good resolution and loss of continuity compared to gap surface- consistent deconvolution. The application of surface-consistent deconvolution to seismic data showed a significant improvement in data quality by reducing random noise, eliminating variability in emissions due to near-surface irregularities, and improving the estimation of statistics.
