  • Abstract:

The limited flexibility and unfriendly shortcomings of the widely used Resist software in geoelectrical data
analysis and interpretation are challenges to the earth scientists. This study employed the Micro soft Visual
Basic programming language code to develop a new WINREST geophysical software that can address these
deficiencies. The developed WINREST software model's frame begins with data quality control, forward
inversion process, iteration and multimedia presentation of the final output. A manually interpreted results
obtained from the acquired Schlumberger array-based depth sounding (VES) data were experimented with
the proposed software. The output of the applied software gives the layer resistivity and thickness parameters
in the range of 366 Ωm to 4190 Ωm and 0.72m to 17.55m, respectively. Using the statistical Nash-Sutcliffe
model efficiency (NSE), the modeling capability and efficiency of the developed WINREST software in the
company of the conventional WinResist software were established. The determined NSE value of >0.9
established the correlated efficiency of the software. The findings established that the newly developed
WINREST software has been found to produce reasonable geological interpretation of a typical hardrock
terrain data with less number of iteration and time. Importantly, its output can be printed directly from this
software graphical unit interface platform. This is an improvement over the popular existing ones in the
market. Thus, this newly developed WINREST software provides a good alternative to other software used
for this purpose.
