The study aims to mitigate the risks associated with operating in a borehole environment. Pore pressure predictions have been conducted using well log traces to identify porous lithological units and the onset of overpressure. The findings of the study indicate a lithology characterised by shaly/sandy structural distributions that significantly influence effective stresses. The top of overpressure for well X01 is located at a depth of 11,450 ft, while for well X02, it is at a depth of 11,801 ft. The forecast for fracture pressure is estimated to range from 9,394 psi for X01 to 9,760 psi for X02. This is substantiated by an estimated fracture pressure gradient of 0.82 psi/ft for well X01 and 0.83 psi/ft for well X02 across parts of the Niger Delta. The results from the assessment of overburden pressure indicate that the study area is over pressured.
