Mediterranean Oil & Gas Friday announced as part of its operational update on its exploration well Teboursouk 1 in Tunisia (Range Operator; MOG 25%) that the CTF - Rig 06 is currently drilling at about 2400 metres of depth.
The well drilled an alternance of beige to dark argillaceous limestones and brown marls to 2222 million of depth, when the drill bit started to penetrate siltstones and sandstones levels with intercalations of marls and shales.
The new lithology can be associated to the Lower Aptian M'Charga formation which is the main exploration target.
Inside the M'Charga formation, gas shows of 0.2% are recording associated with poor cut fluorescence.
The M'Charga formation has been found 200 million deeper than in the well prognosis.
The programme is to penetrate a substantial thickness of the target formation by continuing to drill few hundred metres deeper than the originally planned Target Depth of 2500 million and run logging to evaluate the well results.
The CEO, Sergio Morandi, said "Teboursouk 1's main exploration target has been encountered deeper than expected and some hydrocarbon indication is being recorded during drilling inside the reservoir."
