UPDATE 8-Oil prices drop on surprise U.S. stockpile build

* Venezuela mulls force majeure on some exports -sources

* Washington asks Saudi, others to raise output -sources

* U.S. crude inventories rise 2.1 mln barrels in week -EIA (New throughout, updates prices, market activity and comments; new byline, changes dateline, previously LONDON)

NEW YORK, June 6 (Reuters) - Oil prices fell on Wednesday on signs Saudi Arabia and other big producers may increase production, and U.S. crude slid more than 1 percent on a surprise build in domestic crude stockpiles.

U.S. crude inventories rose 2.1 million barrels in the week to June 1, the Energy Information Administration said, a surprise after analysts had forecast a decrease of 1.8 million barrels. Fuel inventories also rose.

EIA also said U.S. crude output hit a record of 10.8 million barrels a day in the week. Rising production has prompted selling since global benchmark Brent climbed above $80 a barrel last month.

"The continuing increase in crude oil production is weighing on the market, and quite significantly compared to this time last year," Andrew Lipow, president of Houston-based Lipow Oil Associates. U.S. oil production is up 1.5 million bpd from a year earlier.

Brent was down 96 cents a barrel at $74.71 by 10:43 a.m. (1543 GMT) U.S. light crude was down $1.00, or more than 1.5 percent, at $64.50.

U.S. crude was down almost twice as much as Brent, widening its discount from Tuesday <WTCLc1-LCOc1>.

India's oil minister said his Saudi counterpart told him the kingdom was revisiting its policy of cutting production, which has been a major factor in supporting prices.

The U.S. government has unofficially asked Saudi Arabia and some other OPEC producers to boost output, sources told Reuters on Tuesday.

OPEC and Russia will meet on June 22/23 to decide whether to increase production following a fall in global inventories.

The producers have been considering a supply increase of up to 1 million barrels per day, sources told Reuters.

"The oil price is being driven by OPEC and views on how much and how quickly 'OPEC plus' will raise output," Energy Aspects analyst Virendra Chauhan said.

Balancing those expectations has been falling production in Venezuela, which has the world's biggest oil reserves and is a key supplier to American fuel markets. Its output has been hampered by inadequate investment, mismanagement and U.S. sanctions.

Three sources have told Reuters Venezuelan state firm PDVSA is considering declaring force majeure on some exports, after plummeting output and tanker bottlenecks at ports.

U.S. sanctions on Iran also threaten to reduce oil exports from that OPEC producer.

"It's a tug of war between the loss of supply from Venezuela and Iran and the potential output increase from OPEC and U.S. shale," said Tony Nunan, risk manager at Mitsubishi Corp. "$80 is a temporary ceiling for oil until we hear from OPEC."
