    Natural Gas Well Production Problems

        Eng. AlSayed Amer The ongoing process of producing hydrocarbons from a well is a dynamic process and this is often evidenced in terms of changes in the rock or fluid production characteristics. Problems are frequently encountered as a results of many reasons will be discussed. Associated Production Problems There are three basic problems which reduce gas flow from natural gas wells that have a sufficient reservoir pressure, porosity and permeability in a surrounding sand formation: 1-    Restriction of gas flow through casing perforations (sand covers perforations). 2-    Liquid loading of production tubing with water or condensate. 3-    Back pressure on wellhead. Sand production and perforation blockage When sand…
