LIBYA - The Ghadames Basin.

Basement in Libya rises to crop out in the south and south-west. In the western part of the country the Ghadames elements seen in Algeria and Tunisia cross into Libya. Among interesting discoveries in Libya close to the Algerian border is the Al Wafaa gas/condensate field. The field was discovered in 1991 by NOC and is an extension of Alrar gas field in Algeria. Al Wafaa is estimated to have recoverable reserves of about 100m barrels of condensates and 2,000 BCF of natural gas. The field, to be developed jointly by NOC and Agip, will be one of the sources of gas to be exported to Italy by pipeline (see Part Two & Three).

Early exploration by foreign companies in the Ghadames Basin resulted in small oil discoveries which were not developed, because of lack of infrastructure. In the 1970s, NOC discovered several oilfields in the Hammadah Al Hamra plateau. Although they were small, the fields were close to one another and this warranted their development by NOC. The oil is reservoired in Palaeozoic sandstones.

Another petroliferous province has been established in the south-west of that region extending from the Palaeozoic Illizi Basin of Algeria. Oil is reservoired in Palaeozoic sandstones sourced from the same prolific Silurian shales which have contributed so much oil in North Africa. There are traps in that region which occur in folded and faulted structures, as in the case of the Hammada Al Hamra Basin to the north.
