Recherche de données de carottes de forage

Question

<\/HEAD>Bonjour à tous, C'est ma première fois sur ces forums. Je suis un étudiant qui commence tout juste à s'intéresser au GIS et j'essaie de trouver des données pour un projet sur lequel je travaille. Pour mon projet, j'essaie de collecter des données provenant de carottes de forage telles que la profondeur et les contacts d'unités, ainsi que des données géospatiales. L'objectif est d'intégrer cela dans GIS et de développer une continuité sous-surface entre les contacts stratigraphiques. J'ai eu du mal à trouver des données (probablement en raison des droits industriels sur les données de carottes), alors j'ai pensé demander si quelqu'un avait des idées sur où je pourrais trouver ce genre de données en ligne.<\/P> Merci !<\/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!
