Consider the values in the table below for pore pressure and gradient fracture at different depths . A ) According to the following values and regardless of the stuck pipe due to the pressure difference , get the mud window at different depths ? B ) If the basis for selecting the appropriate mud weight is the highest penetration rate , draw a profile of the mud weight relative to the depth Swab and surge margins = 0.2 ppg , safety factor = 0.2 ppg
