Encontrando Dados de Testemunhos de Sondagem

Question

<\/HEAD>Olá a todos, Esta é a minha primeira vez usando estes fóruns. Sou um estudante que está começando a aprender GIS e estou tentando encontrar dados para um projeto no qual estou trabalhando. Para o meu projeto, estou tentando coletar dados de testemunhos de sondagem, como profundidade e contatos de unidades, bem como dados geoespaciais. O objetivo é inserir isso no GIS e desenvolver uma continuidade subterrânea entre os contatos estratigráficos. Tenho tido dificuldade em encontrar qualquer dado (provavelmente devido aos direitos da indústria sobre os dados de testemunhos), então pensei em perguntar se alguém teria alguma ideia sobre onde eu poderia encontrar esse tipo de dado online.<\/P> Obrigado!<\/P> <\/P> -David<\/P><\/BODY><\/HTML>

Finding core data is not easy man and accessing them depends on the area you're working. The best place you're going to find physical copies of the cores is at oil libraries, and each one is different. For example Midland Energy Library has gone through and recorded most of the cores they have in house and have a core list downloadable in excel, which is great BUT since most core reports don't have locational info recorded on the document, MEL does not provide any locational info other than the county and field that they were able to record from the core report.

Midland Subsurface Library has cores also but they don't have any type of list of what cores they have, you can either pay them to research your request or you can visit the library and do the research yourself.

The two ways I search cored wells is identifying on scout cards if they've been cored, or using IHS to locate which wells have cores since they are the powerhouse with the best database built from the massive historical datasets purchased from PI/Dwights.

You can search their database for $25/month and download on a per well basis but just be aware that the core data you can download from them is relatively general compared to the actual detailed core reports available from the libraries.

This is just for Texas, other areas may be completely different.

Hope this helps~

If your state (or area of interest) has  Geological Survey, check with them.  I know here in Utah the UGS has (literally) tons of core samples with associated data.

David, up until last year I would have suggested the Dept. of Energy's Rocky Mountain Oilfield Testing Center (RMOTC) which was about the only non-private oilfield that was liberal with providing lots of data that could be used for various purposes.  However, last year the entire asset including the underlying Teapot Dome reservoir was sold off in to private hands (see http://energy.gov/articles/energy-department-sells-historic-teapot-dome-oilfield) which effectively cut off that content.

You didn't say if you were looking for a soft rock (oil/gas) or hard rock (minerals) example of core but in either case, you might pose the question to the specialist communities in those LinkedIn spaces, namely the Petroleum Users Group (PUG) at https://www.linkedin.com/groups/1832102 and the Esri Mining Users Group (MUG) at https://www.linkedin.com/groups/4017600. Good luck!
