Oil slides $1 as Nigeria supply worries ease

LONDON, June 25 (Reuters) Oil prices fell by more than $1 to near $70 on Monday after Royal Dutch Shell said it was preparing to resume exports from a Nigerian oilfield abandoned over a year ago because of militant attacks.

The news came two days after Nigerian unions ended a strike that had threatened to halt shipments from Africa's biggest oil producer. It could mark an easing of tension in the oil-rich delta where violence has shut a quarter of Nigeria's output.

London Brent crude, currently a better indicator of the global market than U.S. oil, was down $1.14 at $70.04 a barrel by 1418 GMT, off a low of $69.80.

It touched a 10-month high of $72.25 early last week on concern the Nigerian strike might disrupt oil exports.

U.S. crude fell $1.24 to $67.90.

''With the situation in Nigeria seeing a reprieve and high crude stocks in the United States, downward pressure on the prompt month is likely to assert itself in the short term,'' Harry Tchilinguirian, senior oil market analyst at BNP Paribas Commodity Derivatives, said in a research note.

Signs OPEC output is creeping higher to take advantage of high prices also helped tip the market lower.

The 10 OPEC members subject to oil production limits are expected to pump 26.8 million barrels per day in June, up from 26.7 million bpd the previous month, said Conrad Gerber, head of Petrologistics, which tracks tanker shipments.

The International Energy Agency, representing 26 industrialised nations, has repeatedly called on OPEC to raise production to take the heat out of prices that have risen from near $50 in January to within striking distance of a record high above $78. OPEC's next scheduled meeting is in September.

TALKING MONTHS Nigeria's biggest foreign operator Royal Dutch Shell said its Forcados oil export terminal may resume operations in July, more than a year after it was shut because of militant attacks.

A restart would add to supply of Nigerian crude, prized by refiners as it is easy to process into fuels.

Lower Nigerian output since 2006 has boosted world oil prices and prompted Shell to trim production forecasts. Around a quarter of Nigeria's total production is closed because of violence in the oil producing Niger delta.

''There's still a fair bit of production offline. There are some good signs they might sort out these issues, but that's not near term, we're talking months,'' said Tobin Gorey, commodities strategist at the Commonwealth Bank of Australia.

Below normal stocks of gasoline and heating oil in top consumer the United States continued to underpin the market, however. U.S. crude stocks are at a nine-year high but refiners have been struggling to churn out refined oil products.

''(We) believe that the continued stress on the U.S. refining system from the adjustment to more stringent product specifications could lead to further refinery outages, posing a downward risk to U.S. refinery runs,'' said Goldman Sachs.

Since late Friday, Texas refineries operated by Lyondell Chemical Co., Exxon Mobil and Valero all reported upsets, according to regulatory filings.

Speculators took a more bullish view of prices in the week to June 19, lifting their net length in gasoline markets to the highest in three-and-a-half years, while heating oil length rose to its highest since October 2003, data showed on Friday.

NYMEX crude oil speculators also boosted their net length, CFTC data showed. But BNP Paribas' Tchilinguirian said the situation may change. ''The recent easing in bullish developments opens an opportunity for some scaling back of buying positions.'' REUTERS PBB KP2022
