Laboratory Testing of Fracture Conductivity Damage by Foam-Based Fracturing Fluids in Low Permeability Tight Gas Formations

In the case of fracturing reservoirs using fluids, size damage to proppant conductivity caused by treatment fluids is significant, which greatly influence effective execution hydraulic operations. The fluid should be characterized minimum a fracture filled with proppant. A laboratory research procedure has been developed study effect foamed and non-foamed in fractures material. paper discusses results for high quality guar-based linear gels, an innovative aspect work compared frac described most studies simulations. tests were performed based on polymer (HPG—hydroxypropyl guar, liquid powder form). rheology nitrogen foamed-based (FF) 70% was investigated. quartz sand ceramic light LCP placed between two Ohio sandstone rock slabs subjected given compressive stress 4000–6000 psi, at temperature 60 °C 5 h. significant reduction observed that damaged 7.5 L/m3 natural polymer-based fluid. 72.3% 31.5% fluid, are superior guar gum system. For concentration 4.88 g/L, 64.8%, 26.3% These lead conclusion could much less during treatment. At same time, when viscosity coefficient increases few times use necessary carrying capacities properly conducted stimulation can beneficial optimizing type performance tight gas formations.
