TGS To Make Tajikistan, Somaliland Well Log Data Available Online

HOUSTON--(BUSINESS WIRE)--The Geological Products and Services division of TGS-NOPEC Geophysical Company (TGS) has signed an agreement with the Head Geological Department under the Government of the Republic of Tajikistan to build and market a databank of the country's well log data assets. Under the terms of the deal, TGS will have the exclusive right to license to third party exploration companies the several thousand logs that will be sourced from government archives beginning in late Q3 2008. During indexing, scanning and subsequent processing, the data will be subject to TGS' exacting quality control standards.

Tajikistan is considered a highly prospective hydrocarbon play, with existing discoveries and production but very little exploration investment to date.

In a separate agreement with the Ministry of Water and Mineral Resources of the Republic of Somaliland, TGS will also add curve data for the East African nation's wells to its collection.

The TGS well log database contains more than five million well logs from key exploration areas in 23 countries worldwide. All of this data is available to clients via the award winning LOG-LINE Plus!® database which features online access, search tools and immediate download capabilities.
