Harvey Rock Physics has built a unique feature into LogScope. If you need to reliably store colour images that are depth indexed in a publicly available format then you need LogScope here. Our advanced display module supports loading and displaying of images. Once on depth they can be exported in DLIS format for storage and archival.
Loading and displaying core photos alongside of existing depth indexed data is a chore. It usually requires extensive editing of the core photographs to produce a nice depth indexed column that has a start depth and an end depth and is on a reasonably consistent scale.
This work is generally done for comparison purposes and the plot is generally a one off. What LogScope does is provide:
The consistent display of the data and
Storage in a DLIS file
This allows portability of the edited photos as a depth indexed data set as DLIS is readable by a large number of packages. Even if other packages can't decode the photos, LogScope can and will automatically load them when it sees them.
The consistent display of colour images is achieved through templates like most software and one can produce a result similar to that shown below.
LogScope will make an attempt at reading the depths from the file name so if you have well behaved file names and have implemented a stringent standard, LogScope will honour this as shown in the Figure below.
To store the data we have designed a method of storing the data in a DLIS file. The advantages of this are as follows:
It is a documented standard
It is flexible and allows storage of information other than wireline or LWD logs
It can be read by a lot of software packages
It is compact.
What LogScope does is should a project in LogScope contain colour images as a depth indexed image set, this information will be stored inside the DLIS file. Should a user pick up one of these DLIS files in LogScope they can then retrieve the images exactly as you have stored them. The video below gives a step through of how it is done in LogScope.
