DAVOS, Jan 21 (Reuters) - U.S. Energy Secretary Chris Wright told oil company executives on Wednesday that Venezuela's output can rise 30% from its current level of 900,000 barrels per day in the short- to medium-term, three ‌executives who attended the meeting said.

Raising crude output from Venezuela, which sits on the world's ​largest oil reserves, is a top objective for U.S. President ‍Donald Trump after U.S. forces seized Venezuela's leader ⁠Nicolas Maduro in ⁠a raid earlier this month.

Wright's closed-door meeting with the executives took place on the sidelines ‌of the World Economic Forum ​in Davos, Switzerland.

Years of under-investment and sanctions have led Venezuela's oil output to plummet. It pumped 3.5 million bpd ⁠in the 1970s when it ‍accounted for ​7% of global supply, but today represents just 1% of the world's production.

Trump has said the U.S. plans to control ‍Venezuela's oil resources indefinitely as it seeks to rebuild its dilapidated oil industry in a $100 billion plan. So far, his administration has taken 50 million barrels of oil out of Venezuela, and is selling some of it in the open market, Trump said ​on ‍Tuesday. 

Trump met with over 15 oil executives earlier this month at the White House, during which Exxon CEO Darren Woods ​told Trump that Venezuela would need to change its laws before it could be an attractive investment opportunity.

Oil analysts and executives have been skeptical about a quick revival of Venezuela's oil sector, pointing out that its degraded infrastructure would require billions of dollars and years to rebuild.

Venezuela's oil reserves ​are also among the world's costliest to develop, because its crude is so thick and heavy it requires specialised equipment to extract, transport and refine into usable ‍fuels.
