| Abstract | ||
| Reduction in drilling problems particularly those associated with drilling costs can be achieved, to a certain degree, by an early determination of abnormal permeability pressures The prediction of these pressures and fractures degree can be used to define the limit of protective curtain of the drilling boreholes for petroleum purposes. In the present study, two boreholes (A1 and A2) have been selected from Amara oil field, southern Iraq to define the regions of abnormal pressure by using two methods. These methods are the modified d-exponent method and equivalent depth method. These methods are depending on acoustic logging data. Both of them gave coincident results and this may reflect the good accuracy of these methods in determining zones of abnormal pressures using acoustic or sonic logging data. | ||
