Abstract: | In “Static Bottom-Hole Pressure in Wells” (Petroleum Science and Technology, 2006, 24:113-116), Hashim and Makola present a method for the calculation of static pressure gradients in vertical wells. In the present discussion, the methodology proposed by Hashim and Makola is examined and alternate guidelines for the calculation of static pressure gradients are provided. In particular, this work examines their proposed mathematical simplifications and practices that could compromise the accuracy of the calculations. References to recommended practices and procedures for calculating static bottom-hole pressure in gas wells are also presented. |
