PyLogFinder: A Python Program for Graphical Geophysical Log Selection

Many petrophysical or geophysical applications often involve using the same type of geophysical logs from different locations, stored in different Log ASCII Standard (LAS) files. The LAS format is a structured ASCII file format containing log curve data and header information for records of several sub-surface measurements as functions of depth. Checking for specific logs in a large database of LAS files can be painstaking process taking several days. This process is further complicated by the use of mnemonics (different names) for the same log-type by different companies.

PyLogFinder is a Python program for automating the process of analyzing a large database of LAS files and selecting the LAS files that contain specific geophysical logs needed. PyLogFinder uses a mnemonic database of 2665 common mnemonics in searching the LAS file database. The mnemonic database can be easily edited and expanded by the user. This affords the user the possibility of searching the LAS database using mnemonics they are familiar with. PyLogFinder then generates a list and a graphical representation displaying the results.
