U.S. Navy Looms as Venezuela Nears Guyana’s Oilfields

By · March 28, 2025 · 2 min read

U.S. Secretary of State Marco Rubio cautions Venezuela against attacking Guyana, speaking from Georgetown on March 28, 2025.

He highlights the U.S. Navy’s reach, promising severe consequences after a Venezuelan patrol vessel recently entered Guyanese waters near ExxonMobil’s operations.

The oil giant drives Guyana’s rise, producing 650,000 barrels daily, with plans to hit 1.3 million by decade’s end. Venezuela’s Nicolás Maduro revives a 126-year-old border dispute over Essequibo, a region holding Guyana’s 11-billion-barrel oil reserves.

Settled in 1899 by arbitration, Maduro pushes the claim to rally support amid Venezuela’s economic ruin, where oil output lags at 900,000 barrels daily. His navy outmatches Guyana’s modest forces, escalating fears of conflict.

Rubio stresses U.S. support during his Guyana visit, signing a security deal to boost military ties. The U.S. cruiser Normandy joins Guyana’s forces for exercises, signaling readiness to counter threats.

Guyana-Venezuela Standoff

Meanwhile, Guyana’s President Irfaan Ali secures backing from the U.K. and France, leveraging oil wealth to strengthen global alliances. Tensions flare after Venezuela’s March 1 incursion near ExxonMobil’s Stabroek Block site, prompting Rubio’s sharp rebuke.

Maduro dismisses the warning, branding Rubio an “imbecile” and accusing Guyana of provoking unrest. Yet, Venezuela’s crippled oil sector contrasts with Guyana’s ascent, fueled by ExxonMobil, Hess, and China’s CNOOC.

Rubio also visits Suriname, encouraging its offshore oil push near Guyana’s fields, eyeing regional energy growth. The U.S. aims to curb China’s influence, visible in Guyana’s new infrastructure, while securing Western Hemisphere oil stakes.

ExxonMobil’s role amplifies the dispute’s global weight, pitting Venezuela’s ambitions against Guyana’s boom. Guyana transforms from poverty to power since ExxonMobil’s 2015 discovery, dwarfing Venezuela’s faded oil glory.

Maduro’s threats, backed by a 2023 referendum, clash with Guyana’s international shield. Rubio warns that aggression “would not end well” for Caracas, hinting at U.S. intervention.

This standoff blends oil, geopolitics, and military might, centered on Essequibo’s riches. Guyana’s rise challenges Venezuela’s decline, drawing world attention to a border once forgotten. The U.S. stands firm, watching a region where energy shifts reshape nations.
