Data and Image Quality
OGS Strip logs
- Scanned and indexed by ELO
Latitude and longitude values are calculated to the most precise qtr/qtr/qtr/qtr value reported. Not all logs have latitude and longitude information.

Many are of high quality. However, Quality of images varies widely. Mud Log images are of generally poor quality. However, because the mud logs are a unique, important collection we have elected to put them online now. The images will be reprocessed by ELO as funds come available
