The NNPCL Port Harcourt Refinery, officially operated through the Port Harcourt Refining Company Limited (PHRC), remains one of Nigeria’s major downstream petroleum assets. The complex sits in Alesa-Eleme, Rivers State. It consists of the Old Port Harcourt Refinery and the New Port Harcourt Refinery.
Together, both facilities have a combined crude-processing capacity of 210,000 barrels per day. The older plant has a capacity of 60,000 barrels per day. The newer facility has a design capacity of 150,000 barrels per day.
Where Is the NNPCL Port Harcourt Refinery?
The Port Harcourt Refining Company operates in the Alesa-Eleme area of Rivers State, within the wider Port Harcourt industrial environment.
Its location holds strategic importance because Rivers State hosts a major concentration of Nigeria’s oil and gas activities. The refinery also connects to networks for crude supply, petroleum storage, transportation and downstream distribution.
As a result, the surrounding area presents an important environment for infrastructure monitoring, environmental assessment and industrial geospatial analysis.
Port Harcourt Refinery Rehabilitation
The refinery has undergone a major rehabilitation programme. The project aims to restore its processing capabilities after years of operational challenges.
In November 2024, NNPC Ltd announced the restart of the rehabilitated Old Port Harcourt Refinery. The company also reported that trucks had begun loading products such as petrol, diesel and kerosene.
However, the refinery’s operating history has remained complex. NNPC announced a planned maintenance shutdown in May 2025.
In May 2026, NNPC announced a Memorandum of Understanding with Chinese companies. The proposed partnership would support the completion and operation of the Port Harcourt and Warri refineries. It also covers potential upgrades, petrochemical development and gas-based industrial opportunities.
Therefore, anyone discussing the refinery’s current operating status should refer to a specific date. Its operational status has changed over time.
What Does the Port Harcourt Refinery Produce?
The refinery processes crude oil into petroleum products that support Nigeria’s energy and transportation sectors.
These products include:
- Premium Motor Spirit (PMS), commonly known as petrol
- Automotive Gas Oil (AGO), commonly known as diesel
- Household kerosene
- Fuel oil and other refinery products
The 2024 restart highlighted the facility’s role in supplying refined petroleum products to the domestic market.
Why Geospatial Technology Matters Around NNPCL Facilities
Large petroleum facilities contain complex networks of processing units, pipelines, storage areas, roads and other infrastructure. Operators need accurate spatial information to manage these assets effectively.
GIS can support infrastructure mapping, asset inventories, environmental monitoring, site planning and spatial analysis. Drone surveys can also capture high-resolution imagery across large industrial environments.
In addition, 3D mapping can create detailed representations of facilities and surrounding infrastructure. These datasets can support inspection, planning and asset management.
These applications connect naturally with modern oil and gas geospatial services, including surveying, GIS mapping, drone data acquisition, remote sensing and spatial intelligence. GeoInfotech provides geospatial technology services for organizations working with complex infrastructure and spatial data.
The Strategic Importance of Port Harcourt Refinery
The Port Harcourt refinery remains an important part of Nigeria’s downstream petroleum infrastructure. Its history also shows that refinery operations involve more than crude processing.
Rehabilitation, asset management, environmental monitoring, infrastructure planning and operational monitoring all require reliable technical information.
As Nigeria develops its domestic refining and energy infrastructure, GIS, remote sensing, drone mapping and digital asset management can help organizations understand and manage these complex facilities.
