UK-based Tullow Oil expects to begin drilling at a pair of wells in Uganda within a fortnight with one set to spud imminently.
The independent has also successfully appraised a well offshore Ghana after finding gas condensate in “good quality sandstone reservoirs”.
Two wells are expected to commence drilling in Exploration Area 1 in Uganda in the next two weeks, Tullow wrote in a regulatory announcement on Wednesday.
“The OGEC [Ogec Cracow] 600 rig is preparing to spud the high-impact Jobi-East prospect and the OGEC 750 rig is getting ready to drill the first Mpyo exploratory appraisal well to test its upside potential.
“These wells are the start of a major programme of exploration and appraisal drilling, seismic acquisition, and well testing to access the significant remaining upside potential in the basin and further expand the resource base for development.”
Tullow exploration director Angus McCoss said the company is “now gearing up for a five-rig drill-out campaign in the second half of the year”.
The development comes as Tullow struck gas condensate at its Tweneboa-4 appraisal well in the Deepwater Tano license offshore Ghana.
“The well encountered 18 metres of net gas condensate pay in high quality stacked reservoir sandstones which are in static pressure communication with both the Tweneboa-1 and Tweneboa-2 wells,” Tullow wrote.
Transocean’s drillship Deepwater Millennium drilled the well to a depth of just over 4000 metres.
“On completion of operations, the well will be suspended for future use in field appraisal and development. The rig will then move to perform drill stem tests on the Tweneboa-2 oil and gas-condensate accumulations.”
