This is from a 2003 article but the same figures appear in other articles and probably arise from a 2001 rehash of Tunisia's petroleum laws.

"A state owned oil company exists in the form of Enterprises Tunisienne d'Activites Petrolieres (ETAP) but the government is keen for foreign firms to increase their investment in the country both to fund exploration work and to develop many of the smaller fields, which ETAP previously believed to be uneconomic. In order to achieve this it reduced the tax rate for foreign companies investing in the sector from 75 % to 50 % and introduced new oil and gas legislation in 2000.

The government hopes that foreign companies or consortia will be attracted with royalty levels of 10 % for crude oil production and 8 % for natural gas, although ETAP is expected to be allocated 20 % of consortium equity. The acreage on offer lies both offshore in the Gulf of Hammamet and off the north coast, and onshore in the north-west of the country. At the end of 2002, a licensing round was launched for a total of 20 blocks but the results of the round are not yet known."
