15. Type curves help interpret transient-pressure buildup tests that differ from conventional semilog, or Horner, analysis radial-flow behavior. Type curves are groups of paired pressure changes and their derivatives generated from analytical solutions of the diffusion equation with strategically defined boundary conditions. Near-well boundary conditions include constant or variable well-bore storage, partial reservoir penetration, composite radial damage or altered permeability, and propped hydraulic fractures, Borehole trajectory can be vertical, angled, or horizontal. Distant boundary conditions include sealing or partially sealing faults, intersecting faults and sealing or constant-pressure rectangular boundaries. The diffusion equation can be adjusted to accommodate reservoir heterogeneity, such as dual porosity or layering. Commercial software generates type-curve families that account for superposition in time due to flow-rate variations before and even during transient-pressure data acquisition. Automated regression analysis can match acquired data with a specific type curve.
