Kupal Oil Field is one of the important oil fields in the Zagros Basin, located in the eastern part of the Dezful embayment, adjacent to Aghajari Oil Field and Marun Oil Field. Some characteristics of the fold elements, such as the fold interval angle and axial surface, were determined in the Asmari folded horizon using the interpreted seismic profiles. Based on the deviation of the axial surface from the vertical surface and determination of shear angle and shear strain, minimum and maximum quadratic stretch and strain ratio (R) values were calculated in different parts of the anticline. With application of graphical functions the amounts of fold aspect ratio were determined along the anticline. Base on the results, the amounts of shear strain varies from 0.01 to 0.09 in deferent parts of anticline. Also results show the amounts of strain ratio in range of 1.25 to 1.38 and shortening about 5% to 17% in different parts of the kupal anticline oil field.
