Abstract
The Maroon Oil Field is one of the largest oil fields in the Zagros basin located in the eastern part of the Dezful embayment, adjacent to Aghajari, Ahvaz and Kupal oil fields. In this research, the Asmari folded horizon was investigated and with application of interpreted seismic sections, the interlimb angle and axial surface geometry were determined in different sections. Based on the inclination angle of axial surface and using graphical functions, the amounts of shear strain, anticline aspect ratio, strain ratio and shortening values were determined in different parts of the Maroon oil field anticline. Shear strain, strain ratio and shortening zoning maps were prepared along the anticline. Based on the results, the shear strain values vary from 0.15 in the central part and the curvature of the anticline axis to 0.01 in the anticline noses. Also, the results show the shortening values between 2% to 20% and strain ratio values in the range of 1.35 to 1.07 in different parts of the anticline.
