Practical Well Log Standards


Practical Well Log Standards

Executive Summary

This project is working to establish standards for the creation of clearly labeled well log data sets that are accessible to a wide range of E&P professionals. This project leverages previous work, including other POSC standards.  

Project Description

Log data consumers are overwhelmed with the amount of data they are receiving. Currently there are over 50,000 different types of well log curves (or traces); yet, most will agree that the number of useful types of well log curves is somewhere in the neighborhood of 500. Additionally, well log curve names are complex and are changing at an ever-increasing rate; even the petrophysicists can get confused!

This presents several problems for data loading and acquisition, including these:

The result of this confusion can be lost data, lost information, lost time, and lost revenue. 

The establishment of practical well log standards can save companies money through:

Project Status

The next set meetings are tentatively scheduled for the fall of 2002 in at least the same three locations as in the spring. These meeting are intended to cover the following items:

Earlier Project Results

Classification system reconsideration
