Abstract
The foremost objective of producing reservoir material balance analysis is to determine STOIIP and aquifer properties which ensure that the aquifer influx into the reservoir reliably offsets production. But the different views canvassed on this analysis are hampered by the limitation that the material balance equation is an ill-posed pressure-implicit depletion function. So, this program has adopted a robust and self-adaptive nonlinear regression to advance material balance analysis. The program validated two examples and pointed out the shortcomings of the authors solutions.
