Fracture Height Growth Containment Using Low Permeability Bridging Agents to Stimulate Tight Gas Sands with Weak Barriers. Topical Report January 1982-March 1985

摘要

The topical report evaluates the feasibility of using bridging agents to control fracture height growth in tight (low permeability) gas formations bounded by base rock and/or overlain by an overburden rock, which are not barriers to fracture migration. The bridging agent technique is one of the four proposed modified hydraulic fracturing techniques that attempts to improve gas production from tight formations by controlling fracture migration. Analytical models for determining fluid pressure profiles within the fracture, and for determining flotational velocities for the bridging agent slurry were also developed.
