Overall drilling density of the basin is 3.3 wells per 100 km<sup>2</sup>, with an average field depth of 2,100 m. Recent indications of hydrocarbons within grabens suggest that these areas have potential as well as clastic reservoirs beneath the carbonate reservoirs in the Central Sirte Basin. The offshore area beyond 200 m depths is largely unexplored. </p> <div class="mw-heading mw-heading2"><h2 id="Geologic_setting">Geologic setting</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Sirte_Basin&action=edit&section=4" title="Edit section: Geologic setting"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The Sirte Basin province is considered to be a <a href="/wiki/Type_locality_(geology)" title="Type locality (geology)">type locality</a> of a continental rift (extensional) area and is referred to as part of the Tethyan rift system.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> According to the designation scheme of Bally and Snelson, it is classified as 1211; a cratonic basin located on earlier rifted grabens on a rigid <a href="/wiki/Lithosphere" title="Lithosphere">lithosphere</a> and not associated with formation of megasutures.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Clifford terms it as an interior fracture basin near the <a href="/wiki/Tectonic_plate" class="mw-redirect" title="Tectonic plate">tectonic plate</a> margin, which characteristically has an axis at an angle to that margin.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p><p>The area's structural weakness is exemplified by alternating periods of <a href="/wiki/Tectonic_uplift" title="Tectonic uplift">uplift</a> and <a href="/wiki/Subsidence" title="Subsidence">subsidence</a> originating in the Late Precambrian, commencing with the <a href="/wiki/Pan-African_orogeny" title="Pan-African orogeny">Pan-African orogeny</a> that consolidated a number of proto-continental fragments into an early <a href="/wiki/Gondwanaland" class="mw-redirect" title="Gondwanaland">Gondwanaland</a>.
