OSLO, June 11 (Reuters) - Norway's oil production rose to a preliminary 2.11 million barrels per day on average in May from 2.03 million in April, Norwegian energy officials said on Wednesday.

Production of natural gas liquids (NGL) and condensate rose to a preliminary 371,000 barrels per day in May from 355,000 in April, the Norwegian Petroleum Directorate said in a statement.

Norway is the world's fifth-biggest oil exporter and the second-largest supplier of natural gas to Europe.

Final figures for April showed that gas production rose to 8.5 billion standard cubic metres from 8.3 billion cubic metres in the same month a year ago.

The directorate (NPD) did not give preliminary figures for May gas production. Final figures for May will be available in early July, when it will also publish preliminary June data.

"So far this year the average daily production has been just above 2.1 million barrels of oil," the NPD said, referring to output for the January-April period.

Norway is struggling to maintain oil production on its continental shelf against a long-term decline at ageing North Sea fields, though gas output is still rising steeply, keeping total Norwegian petroleum production on an upward path.

Total production, including oil, gas, condensate and NGL, rose to 84.2 billion standard cubic metres of oil equivalent in the four months to the end of April from 83.4 billion standard cubic metres in the year-ago period, the NPD said.

In April, Statfjord C, Statfjord Nord, Statfjord South and Sygna were closed for 21 days according to plan. Ula and Tambar fields were shut down for eight days due to preparations for connections of a new gas module, the NPD said. (Reporting by John Acher)
