Testing TotalDepth With Recorded Data¶
TotalDepth is tested against a diverse data set of real world files. The test set is split into small/medium/large datasets.
Small Test Set¶

Medium Test Set¶
The Medium Size Test Set is 20,000+ files (130Gb+) of typical oilfield data. Here is the approximate breakdown of the test set:
File Type | Files | Total Size | Notes |
---|---|---|---|
BIT | ~500 | ~1.5Gb | Largest file is around 6Mb. |
LAS v1.2 | ~500 | ~1Gb | Largest file is around 16Mb. |
LAS v2.0 | ~20,000 | ~30Gb | Largest file is around 250Mb (RP66V1 converted files are much larger). |
LAS v3.0 | A few | ~0 | Rarely present, their absence is not considered significant. |
LIS | ~2000 | ~2GB | Largest file is around 60Mb. Around half have TIF markers. |
DLIS (RP66V1) | ~800 | ~100GB | Largest file is around 4GB. About one quarter are corrupted by TIF markers. |
DLIS (RP66V2) | 0 | 0 | Not present, their absence is not considered significant. |
Other | Various | Various | Various files such as PDF, TIFF, miscellaneous binary files and unstructured ASCII. If present then their contents is not considered significant but archives containing these should be processed without drama. |
The layout of the test set is typical of an oilfield repository, typically by well, with a well having an unspecified directory structure and a mix of file types in each directory.
The aim is that TotalDepth can process 97+% of the files in this archive in the formats that TotalDepth supports.

Synthetic Test Set¶
TotalDepth can generate arbitrary sized files in a number of formats and this test set is used for performance analysis. This test set is not distributed with TotalDepth but the means to create it is.
