Tullow cheers 'significant' oil & gas find

Tullow Oil said its Tweneboa-2 exploratory appraisal well, some 6 km southeast of the Tweneboa-1 discovery, has intersected a significant combined hydrocarbon column. Results of drilling, wireline logs and samples of reservoir fluids establish that Tweneboa is a major oil and gas-condensate field.The well has encountered a gross reservoir interval of 153 metres containing 32 metres of net hydrocarbon pay in stacked reservoir sandstones, comprising a 17 metre oil bearing zone below a 15 metre gas-condensate bearing zone.A combined hydrocarbon column of at least 350 metres has been established between the lowest known oil in Tweneboa-2 and the top of the gas-condensate at Tweneboa-1, demonstrating this is a highly prospective and extensive turbidite fan system that will be evaluated with additional drilling, Tullow added.'Tweneboa-2 was a bold step-out which has successfully proven the significant extent of a major new oil and gas-condensate field offshore Ghana. Such an achievement provides a very good start to our exciting 2010 Equatorial Atlantic campaign. We look forward to further appraising this discovery later in the year,' Angus McCoss, Exploration Director, said.
