Oil production in Tunisia peaked in 1980. Most onshore
oil has been produced from the El Borma field near the Algerian border,
which came onstream in 1966. Most offshore oil has been produced from
the Ashtart field in the Gulf of Gabes, onstream in 1973.
A few smaller accumulations, especially offshore, have offset depletion
in these fields allowing output to increase from 2007 but only a limited
number of marginal prospects remain.
Tunisia’s gas mostly comes from the offshore Miskar field. Other
potential developments exist which are allowing output to grow but these
will not be large enough to prevent slow declines in gas output after
Tunisia’s oil consumption slowly increased up to 2005
despite escalating oil imports as the country’s economy was relatively
strong. Recent expansions of output will lead to a brief period of
export with consumption also increasing but more slowly.
Gas consumption has increased in line with indigenous gas production and
expansion of gas demand is expected to continue with imports from
Algeria continuing after 2012.
