LONDON, Aug 11 (Reuters) - British wholesale natural gas prices rose on Monday morning on the back of an unplanned outage at a North Sea gas field, lower temperature forecasts and concerns about the transit of gas from Russia via Ukraine.

Day-ahead British gas prices increased by 1.00 pence to 38.50 pence per therm by 0839 GMT. Gas for immediate delivery was up 0.30 pence at 38.00 pence per therm.

"The prompt has ticked up on the back of another outage at J-Block, lower temperature forecasts and bullish curve contracts," a gas trader said.

ConocoPhillips' North Sea J-Block natural gas field went into an unplanned outage on Sunday, the operator said.

The shutdown started at 3:20 p.m. local time (1420 GMT) and ConocoPhillips said an investigation was under way as to when the field would return to service.

The field's typical production rate is 10 million cubic metres per day.   Continuación...
