Determining permeability using formation testing data

A system for determining permeability of an earth formation of a reservoir, the system comprising:

• at least one computing device configured to perform the following steps:
• receiving formation testing data measured at multiple measurement stations along the drilled well, a measurement region of each measurement station covering multiple horizontal layers and measurement regions of two immediately adjacent measurement stations overlapping at least one horizontal layer, said multiple measurement stations including a dual-packer module or a dual-probe module and at least one observation probe positioned separately along with the drilled well;
• defining layering of the earth formation;
• determining a geological model for each horizontal layer;
• modeling pressure transient in each measurement region by representing pressure transient within a horizontal layer using an analytical solution and representing pressure transient between two horizontal layers using a numerical solution, the analytical solution selected based on at least one of the respective geological model and data regarding a drilled well of the reservoir, and a parameter of the analytical solution and a parameter of the numerical solution being determined based on the formation testing data of one of the two immediately adjacent measurement stations;
• and
• determining the permeability of the earth formation based on the pressure transient model.
