There is falling output in Venezuela and elsewhere so the oil market is till tightening despite rising US output.

From the IEA Oil Market Report March 2018

"In the meantime, market re-balancing is clearly moving ahead with key indicators - supply and demand becoming more closely aligned, OECD stocks falling close to average levels, the forward price curve in backwardation at prices that increasingly appear to be sustainable - pointing in that direction. In our chart, we assume for scenario purposes that OPEC production remains flat for the rest of 2018, and on this basis there will be a very small stock build in 1Q18 with deficits in the rest of the year. With supply from Venezuela clearly vulnerable to an accelerated decline, without any compensatory change from other producers it is possible that the Latin American country could be the final element that tips the market decisively into deficit.
Moving further into the future than is usual in this Report, in the IEA's five-year outlook, published in Oil 2018 - Analysis and Forecasts to 2023, we highlighted how in 2017 discoveries of new resources fell to a record low of only 4 bn barrels while 36 bn barrels were actually produced. We also pointed out that in 2018 investment spending is likely to grow only by 6% having barely increased at all in 2017. To 2020, production increases from non-OPEC countries are by themselves enough to meet demand growth. After that time, the pace of growth from these countries is less certain, and the market might well need the supplies currently being held off the market by leading producers."​
