News that oil and gas explorer Ophir Energy will let off steam and flog some of its interests in an African gas field was welcomed by the City yesterday.
Ophir has had a troubled year as two of its major investors reduced their stakes and a disappointing drilling programme has meant the shares are down 25 per cent since the start of the year.
News of a potential deal in Tanzania was the first piece of good news for the African-focused explorer in a long while.
Analysts at Nomura said the deal will "provide a genuine reference point for valuation" and because it is retaining some ownership "it leaves Ophir at a relatively attractive price to gain access to further upside in Tanzania through block 7 and East Pande with the Mlinzi and Tende prospects planned to be drilled".
A report from India suggested Ophir is in talks to sell to state-run gas company GAIL, but other traders said that there could be a number of interested parties involved.
Ophir said in a statement that a sale process is "ongoing to sell down a part interest in these blocks but there is no certainty that this process will conclude successfully".

Meanwhile, the fizz went flat at drinks giant Diageo when punters swallowed the bad news coming from rival Pernod Ricard.
The French drinks group, which owns Absolut Vodka, Martell cognac and Chivas Regal whisky – reported a 9 per cent fall in first-quarter sales which it blamed on a slowdown in emerging markets and currency fluctuations. Pernod, which is the second-biggest drinks group after Diageo globally, follows other brands which have blamed a Chinese government crackdown on "gift giving" among top-level officials for weaker sales in the region.
Diageo and SAB were hit and, respectively, tumbled 16.5p to 2012.5p and 14.5p to 3,233.5p. Pernod fell by more than 3 per cent in Paris.
