SINGAPORE, July 18 (Reuters) - Singapore's middle distillates stockpiles ballooned week on week, gaining by more than 30% as a surge of jet fuel/kerosene total imports - mainly from India - offset gains in diesel/gasoil net exports.

Inventories of diesel/gasoil and jet fuel/kerosene at oil storage hub Singapore climbed to 11.145 million barrels for the week ended July 17, compared with 8.454 million barrels the previous week. (Reporting by Trixie Yap Editing by David Goodman )
