Data Management in Flows

Danomics is actively developing a number of data management tools to help you get your data ready to interpret faster than ever before. In this video I’ll review how you can use these tools to understand if there are structural problems in the format of your LAS data, understand your curve mnemonics, and perform a simple cleaning operation. In this video we’ll be using the following blocks in Danomics Flows (File >> New Flow…):

• LogHealthCheck – This tool will be used to evaluate structural problems in your LAS files
• MnemonicsAnalysis – This tool will be used to evaluate the coverage of your Mnemonics in the alias table
• NullRepeatedLogSamples – this tool will be used to remove repeated values from your well logs

This video (17 minutes) will cover all three tool types. More information, including screenshots from this demo can be found below.

Log Health Check Tool

The output from the LogHealthCheck tool is accessed by clicking on the job log icon (sheet of paper). The report will list all issues noticed on a well-by-well basis as well as a summary view at the end of the report, as shown here:

One useful trick if you want to just see all of the wells that encountered a specific problem is to choose to only run a single check by clicking on the “Selected” option in the “Checks” radio group.

Mnemonics Analysis

In the Mnemonics Analysis tool we evaluate how many of each curve type there are present in your log database as well as what those mnemonics are aliased to. Running this tool is a useful way to understand if some of your data may not be getting used in your petrophysical analyses and if you need to modify the default alias table. To use this tool you’ll first create a new flow (File >> New Flow). Next you’ll add a LogInput block and a MnemonicsAnalysis Block. Finally, once the job runs, you’ll access the report (as shown below) by clicking on the job log icon in the Jobs menu.
