Geertsma's Model
Geertsma
Matlab implementation of Geertsma's equation (Geerstma, 1973) for subsidence and inflation of a reservoir in a homgeneous medium. In-line syntax is described in the comments. See the files for further documentation.
-
'Geertsma_Checklist': runs a quick check on the functions.
-
'Geertsma_Exact': calculates the vertical compaction on the line above and below a compacting disc
-
'Geertsma_Example': runs a numerical example, with some plot suggestions.
-
'Geertsma_Symbolic_ToolBox': modeling function, with detailed explanation. Use this if you have the symbolic toolbox installed
-
'Geertsma_No_ToolBox': modeling function, with detailed explanation. Use this if you do not have the symbolic toolbox installed. Accuracy is slightly worse.
-
Other functions are numerical implementations necessary in the absence of the Symbolic Toolbox.
