Many of the problems in stimulating the Morrow are due to the properties of the rock and are common to other low permeability Pennsylvanian sandstone formations. These problems include low permeability, clay particle migration, iron, scale, fluid retention, and high frac gradients. If, after perforating, the well does not produce satisfactorily, an acidizing treatment will be required. The purpose of the acidizing treatment may be either to remove or bypass permeability damage around the well bore or to insure that the perforations are open and the well is ready for a fracturing treatment. Each purpose uses a different acidizing technique and acid systems to accomplish its task. Each is described. Dilute hydrochloric acid (1 to 5%) is the base fluid most generally used in fracturing the Morrow. The experience of several successful treatments in the Morrow has proved that it can be successfully stimulated if the potential gas production is present to be stimulated.
