LONDON, Sept 27 (Reuters) -Exports of four key Nigerian crude oil grades scheduled for November represent a big jump from the scheduled output in October, preliminary programmes show.

* Loadings of Bonny Light, Bonga, Qua Iboe and Forcados streams are expected to hit 746,000 barrels per day (bpd) in November, versus 569,000 bpd in October.

* The jump is largely driven by ten cargoes of Forcados scheduled for November, programmes shared by a trader showed. Exports of the stream resumed in mid-August, roughly a month after loadings of the medium sweet grade were suspended.

* In November, 323,000 bpd of Forcados are scheduled to load, versus 223,000 bpd in October.

* On Monday, it emerged that Nigeria's key Qua Iboe crude stream is scheduled to load 158,000 barrels per day (bpd) in November. Meanwhile, Bonga and Bonny Light will each load four cargoes in November, with each cargo comprising about 1 million barrels.
