Hi Mohammad,

I'm a little unclear on what you want to digitize. If I understand right, a log sheet is a spread sheet of information. ArcMap deals with geographic objects. So, digitizing something in ArcMap involves defining its shape and location on earth (point, line, polygon). All the sorts of information in a spread sheet can then go into the attribute table of that mapped object, but the primary data element is the geographic object - a ground water well in your case, I think. I'm assuming these log sheets are with respect to wells - if you map the wells, you can then write the contents of the log sheets to them as attributes.

I might not be understanding your question correctly... please clarify if so.

Cheers,

P

Dear Mohammad

Geoscience information theory tell us that at least you need two separated systems that can work together. One of this is the GIS who can manage the well geospatial position and a specific database for log information. The problem here is the specific well information system must be compatible with the ArcGIS product.

I know that there are several companies that are selling specific groundwater modules for ArcGIS, may be Schlumberger has a product

But if you only  want to model the well position, underground orientation and compositional data I think you can make some experiments using ArcGIS 3D.

Wells can also be modelled with simple and traditional databases, but that cannot fulfill your requirements. Let's see a simple example in geospatial sql:

create table well_position (

geometry POINT,

well_id (text or number) unique,

we_name text, 

etc....

)

create table well_underground (

well_id (text or number) unique,

segment_id (text or number)

from_segmet (text or number)

to_segment (text or number)

from_deep Number,

to_deep Number,

segment_lenght Number,

orientation Number,

inclination Number,

composition TEXT,

porosity Number,

permeability Number,

etc...

)

Then you need to create a relationship between tables

select * from well_position, well_underground where well_position.well_id = well_underground.well_id

Other option you have is some free but copyrighted software like this

Anyway you have several options to see. I hope those recommendations will help yourself.

If you need to digitize printed paper forms of electrical (wire-line) logs from oil and/or gas wells, you need to use software such as neurolog. This software will give you logs in .las format which can be imported to another software for interpretation.

I hope this helps.

Hi Mohammad,

If you need digitize logging curves from logs sheets, you can use the EasyTrace software (http://www.easytrace.com/en).  You can export the result in the ArcMap, if you need.

I used EasyTrace for this purpose. It is not a special soft for log digitizing, but it's simple and usefull.

 Hi Victor,

Is there anywhere I can find a video tutorial on how to digitize logging curves from log sheets using EasyTrace, and can this software save files in LAS format? 

Hi, Jude,

I don't know about video tutorial for EasyTrace, actually. I wrote program, which convert result files of EasyTrace to the LAS (I have no Neuralog at those moment). As I wrote above, EasyTrace is not spetial soft for log digitizing. As wrote Ibrahim, Neuralog is a program special for digitizing logs. Its more usefull, than EasyTrace.
