Module for plotting areas of particular patterns wirth well log data.
Created on 1 Apr 2011
Note on patterns in XML file in: formats\IWWPatterns.xml
There are elements thus:
<Bits>/+7/7v/u/+7/7gAA7/7v/u/+7/7v/gAA</Bits>
<PatternHeight>12</PatternHeight>
<PatternWidth>15</PatternWidth>
Frequency analysis shows that the characters used are ‘+’, ‘/’, A-Z, a-z, 0-9 so this looks like base64 encoded. Length is always 32 chars (256 bits). Pattern size suggests 12*15=180 bits.
Examples:
>>> base64.b64decode(b'/+7/7v/u/+7/7gAA7/7v/u/+7/7v/gAA')
b'ÿîÿîÿîÿîÿî ïþïþïþïþïþ '
