Aquifer Influx & Water Encroachment Model: Carter-Tracy, Fetkovich & Material Balance Support
Estimate aquifer water influx with Carter-Tracy and Fetkovich models, compare results, and link to material balance drive energy, dedicated aquifer workbook.
TAGLINE
Estimate aquifer water influx with Carter-Tracy and Fetkovich models, compare results, and link to material balance drive energy — dedicated aquifer workbook.
WHO IT'S FOR
Reservoir engineers modeling water drive support and aquifer influx for material balance and simulation input.
WHAT IT DOES
Applies time-stepped Carter-Tracy (infinite-acting, Edwardson pD) and Fetkovich (pseudo-steady state, Wei and J) aquifer models to the pressure history, compares the two influx estimates with 1:1 crossplots, and computes the water drive index for material balance. Aquifer thickness, permeability and water viscosity are inputs.
