UPDATE 1-Nigeria's Rivers state buys Shell's stake in Ogoniland oilfield

(Adds background, detail)

PORT HARCOURT, Sept 30 (Reuters) - Nigeria's Rivers state has purchased Royal Dutch Shell's stake in an oil mining license in the restive Ogoniland region, the state's governor said on Monday.

The block under license, OML 11, has been undeveloped for nearly 25 years, since the execution of regional activist Ken Saro-Wiwa under the military government of Sani Abacha.

The field is among several onshore assets that Shell had been trying to sell in Nigeria.

Talks with at least one potential buyer fell through due to the tense nature of community relations, sources told Reuters.

Rivers state governor Nyesom Wike said they had bid $150 million for the 45% stake in the asset.

The statement said OML 11 had the potential to produce 250,000 barrels per day (bpd). Nigeria currently produces roughly 2 million bpd of crude oil and condensates daily. (Reporting By Tife Owolabi; Writing by Libby George; Editing by Jan Harvey)
