The estimation of pore pressure gradient is a necessary requirement to safely, economically and efficiently drill an oil and gas well. As such this project sought to predict the pore pressure gradient of the Jubilee field using Eaton’s correlation and Hubbert and Willis’ correlation and then further comparing with the actual pore pressure gradient from the field. This was done to know which of the methods predicts best. The Jubilee Field is the most prolific oil and gas field in Ghana among others. Four different Wells from the Jubilee were analyzed and the results obtained were used to make necessary conclusions. The results obtained showed a deviation of -50% from the normal field data (0.481) when Eaton’s correlation was used. This showed that the Eaton’s correlation underestimated the pore pressure gradient. Similarly, the results obtained from Hubbert’s and Willis Correlation showed approximately +24% increase in the normal field pore pressure gradient. The pore pressure from the field gave a strong correlation with an error of prediction less than 2%. The Hubbert and Willis’ method predicted better than the Eaton’s method for this project. The mathematical correlation model for the field analysis can therefore be used to calculate the pore pressure gradients for other Wells with an error of prediction less than 2%.
