Advanced analytical pressure-transient analysis relevant to geothermal wells
Abstract
Abstract All analytical models are solutions to the diffusivity equation, and many simplifying assumptions are required. The earliest and simplest models and methods are described in Chapter 4, Introduction to Pressure-Transient Analysis. In this chapter, more complex analytical models are described, in which some of the assumptions are relaxed or eliminated. Important examples are reservoir boundary models, fractured reservoir models, single-fracture models, multiphase reservoir fluid, stress-sensitive reservoirs and non-Darcy flow. These advances were made within the petroleum industry but are relevant for the geothermal industry as these are also common features of geothermal reservoirs.
