Seismic Data Processing of Subba Oil Field in South Iraq

Abstract

Evaluation study was conducted for seismic interpretation using two-dimensional seismic data for Subba oil field, which is located in the southern Iraq. The Subba oil field was discovered in 1973 through the results of the seismic surveys and the digging of the first exploratory well SU-1 in 1975 to the south of the Subba oil field. The entire length of the field is 35 km and its width is about 10 km. The Subba oil field contains 15 wells most of them distributed in the central of the field.

     This study is dealing with the field data and how to process it for the purpose of interpretation; the processes included conversion of field data format, compensation of lost data and noise disposal, as well as the application of normal moveout correction for the purpose of improving the quality of seismic sections, using Omiga software at the processing department/ Petroleum Exploration Company

After processing RMS velocity map was done also constructed from the processing data and showed a low velocity compatibility north of the study area and an increase in velocity to the south of the oil field
