Water Influx Models

Water Influx Models. Other popular methods used for calculating water influx include the steadystate method of Schilthus and the pseudosteadystate model of Fetkovitch which are only applicable to a limited range of flow conditions or reservoiraquifer geometries.

commonly used water influx model [15] This model is basically a solution of the radial diffusivity equation hence it yields an accurate estimate of water encroachment for practically all flow.

PDF filemodel by removing the superposition • Approximation of the diffusivity equation • Assumes constant water influx rates over each finite time interval • Uses dimensionless time and dimensionless pressure influence as by EH • Accuracy depends on time step • Excellent match with EHmethod Fetkovich.

Several models have been proposed for quantifying the influx of water accumulated into the reservoir Among the classic models the most used are van Everdingen & Hurst (1949) Hurst modified (1958) Fetkovich approximate (1971) Carter & Tracy (1960) Allard & Chen (1984) and Leung (1986).
