SOTE Emergency Variant Reaches 70% Completion; OCP Pursues USD 135 Million Definitive Solution

Project Status

Petroecuador's emergency variant on the Sistema de Oleoducto Transecuatoriano (SOTE) — the primary crude export pipeline from Ecuador's Amazonian production basin to the Pacific coast export terminal at Balao — has reached approximately 70% physical completion, per El Universo citing Minister of Environment and Energy Inés Manzano.

Key specifications from the official on-record account:

• Current advance: "registra un avance de alrededor del 70 %"
• Length: "Tendrá una extensión de 1.983 metros" (1,983 meters)
• Expected operation: "estaría en operación desde mayo" (from May 2026)

This is Variant 10 — the operational emergency bypass designed to restore crude flow while the permanent infrastructure solution is tendered and built.

The Underlying Threat

The emergency variant was necessitated by what the source characterizes as "la agresiva erosión del río Loco, que creció rápidamente debido a las fuertes lluvias" — aggressive erosion of the río Loco driven by unusually heavy rainfall.

Río Loco erosion is distinct from — though related to — the well-documented regressive erosion problem on the río Coca that has threatened the Coca Codo Sinclair hydroelectric facility and prior SOTE alignments. Ecuador's oil-export infrastructure in the Oriente is exposed to a growing pattern of hydrological instability that is increasingly treated as a structural, not episodic, risk.

The Definitive Solution

OCP — the parallel private-sector heavy-crude pipeline — is running procurement through the Servicio Nacional de Contratación Pública (Sercop) for the definitive variant. Per the source:

• OCP status: "la empresa OCP se encuentra realizando procesos con el Servicio Nacional de Contratación Pública (Sercop)"
• Cost: "costaría aproximadamente $ 135 millones"
• Route specs: "un trazado de 47,8 km para el SOTE y de 49,68 km para el poliducto"

The definitive route specifications indicate a meaningfully longer realignment than the 1,983-meter emergency bypass — consistent with building out of the active erosion corridor rather than working around it.

Infrastructure Exposure Table

System	Operator	Role
SOTE	Petroecuador	Principal state-owned crude pipeline
OCP	Oleoducto de Crudos Pesados (private)	Parallel heavy-crude line
Poliducto	Petroecuador	Refined-products line (part of the definitive realignment)

All three systems operate through the same erosion-exposed corridor, making the definitive variant effectively a multi-line infrastructure project.

What to watch

• May 1 emergency variant startup. The May operation date is the first milestone. A delay would force further reliance on partial-flow operations and affect monthly export volumes.
• Sercop award timeline. The definitive variant procurement is mid-process. Watch the Sercop portal for the award decision, expected contractor, and construction timeline.
• $135 million financing structure. Whether OCP finances through its own balance sheet, multilateral support, or a project-finance structure will signal OCP's financial position and appetite for capex.
• Petroecuador production impact. Monthly production and export figures for April and May will show whether crude flow has been maintained through the emergency phase. A material shortfall would affect fiscal revenue forecasts.
• Hydrological pattern in the upper Coca/Loco basin. Ecuadorian meteorological authorities have been tracking rainfall anomalies; persistent precipitation outside historical norms raises the probability of further erosion events affecting the corridor.
