Nigeria’s government data has shown that its oil production continued to fall down during September due to a halt in onshore production, Bloomberg reported.

According to the data, the country’s daily production recorded an average of 1.14 million barrels of crude oil and condensate during the last month, which is about 42,000 barrels fewer than in August.

Nigeria is suffering from rampant theft on the pipelines leading to shutting down wells and killing off investment. Production of three major export grades – Bonny, Brass and Forcados – has shriveled in recent months, with none of them accounting for more than 8,000 barrels per day in September.

Nigeria aims to add 500,000 barrels a day to its production by the end of November, mainly by resuming operations at Shell’s Trans-Niger pipeline and Forcados terminal, Mele Kyari said, the chief executive of the state-owned energy company.
