LONDON, May 29 (Reuters) - U.S. WTI Midland crude differentials rose on Thursday while North Sea loading programmes showed a sizeable rise in supply of benchmark grades for July.

JULY PROGRAMMES

* Supply of the five North Sea crude oil grades underpinning the dated Brent benchmark will average about 565,000 barrels per day in July, compared to 350,000 bpd in June, loading programmes showed on Thursday.

PLATTS WINDOW

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

* One cargo traded, a source said.

* WTI Midland: Total bought from Phillips 66 a June 13-17 cargo CIF Rotterdam at dated Brent plus $1.10, or dated Brent plus 11 cents on a FOB basis, according to Reuters calculations.

* That was up 5 cents from an offer on Thursday.
