Attention has turned to whether an oil-related understanding between the United States and Venezuela can actually lower international crude prices. The short answer, on most analyses, is that immediate effects are unlikely.

Venezuela holds among the world's largest proven crude reserves. But reserves and output are separate matters.

Reserves versus capacity

Much of Venezuela's crude is extra-heavy oil from the Orinoco Belt. Its viscosity makes it difficult to move through pipelines without diluent or on-site upgrading — and those facilities have seen utilization fall after years of underinvestment.

Raising output requires well restoration, refurbishment of upgrading facilities and repairs to export terminals together. Industry estimates put meaningful increases at one to two years away, with full recovery considerably longer.

The refining constraint

Another variable is the limited set of refineries able to process this crude. Plants configured for heavy, high-sulfur grades are concentrated along the U.S. Gulf Coast and a few other locations. If supply rises but the capacity to absorb it is fixed, price effects stay confined to particular grades.

Investment incentives

Political uncertainty is a heavy discount factor in oilfield development, where payback horizons are long. Without confidence in how long an arrangement will hold, large capital does not arrive.

For Asian consumers

For importers such as Korea, China and Japan, the prospect of supply diversification is of interest. But shipping distance and crude characteristics mean Asian refiners' sourcing will not change immediately.
