Comparing methods of predicting pore pressure [ READ ]

Comparative analysis uses certain criteria to judge various alternatives in the analysis. These criteria include the values of the alternatives and the likelihood of obtaining them. The petroleum industry constantly seeks for ways to cut down cost of exploration and development. An improvement on the ability to predict events ahead of the bit is the key to achieving this goal. Estimation of pore pressure finds itself so vital in the industry, especially in planning and drilling a modern deep well. No wonder there abound several methods for its prediction. The most common methods of predicting pore pressure in the industry were compared in this study. Seismic travel time data for a well in the Louisianan basin was used for the comparison. The methods compared were the equivalent depth, ratio, Eaton, Pennebarker, Hottman and Johnson, and, Matthew and Kelly. Based on the analysis in the study, the method by Eaton is the most accurate.
