LONDON, Sept 27 (Reuters) -North Sea and U.S WTI crude differentials were steady on Friday as attention in the market focused on the emergence of loading programmes for November.

NOVEMBER PROGRAMMES

* Supply of the five North Sea crude oil grades underpinning dated Brent will average about 606,000 barrels per day in November, compared with 610,000 bpd in October, loading programmes showed.

PLATTS WINDOW

* Indications are on a free-on-board (FOB) basis unless marked as cost, insurance and freight (CIF) or delivered at place (DAP).

* No deals, a trade source said.

* Ekofisk: Gunvor offered Oct. 11-13 at dated Brent plus $1.80, and equal to roughly dated Brent plus 83 cents after allowing for the Platts quality premium according to Reuters calculations.

* Forties and Brent: No indications, last valued at dated Brent plus 65 cents.

* WTI Midland: No indications, last traded on Monday at dated Brent plus $2.75 CIF Rotterdam or about plus $1.88 on a FOB basis according to Reuters calculations.

* Forties and Brent are both the cheapest grades in the dated Brent basket, and therefore set the benchmark price.
