Attock Refinery Limited resumed operations and the movement of oil supplies late Wednesday night [1, 2, 3].

The restoration of refinery operations is critical for maintaining the national fuel supply chain and preventing price volatility in the region. Any disruption to the crude oil flow into the facility prevents the production of petroleum products, which can lead to widespread shortages across the capital and surrounding areas.

According to reports, the shutdown was triggered by traffic restrictions and road closures in Islamabad [1, 2, 4]. These restrictions halted the movement of crude oil tankers and the distribution of petroleum products, forcing the refinery to stop operations. Some reports indicate that the refinery halted its main crude unit specifically [4].

Authorities and the Oil Tankers Association have worked to resolve the transport disruptions. The easing of road closures allowed tankers to move freely once again, enabling the refinery to restart its processing units. The refinery is now functioning at normal capacity, and the supply of oil products to the market is moving forward [3].

Because the transport disruptions were caused by city-wide road closures, the refinery's ability to operate depends heavily on the transport infrastructure of Islamabad. This event highlights the vulnerability of the refinery's logistics chain to urban traffic management decisions. The refinery has not provided a detailed timeline of the exact same-day shutdown and restart, but the movement of oil supplies has been restored [1, 2].

This incident underscores the fragility of critical energy infrastructure logistics in Pakistan's capital. When urban traffic restrictions are imposed for security or administrative reasons, the same mechanisms that protect the city can inadvertently paralyze the refinery's crude oil intake and product distribution, creating a potential energy security risk.
