Residents of Uzere Kingdom in Isoko South Local Government Area of Delta State have lived with a new and unsettling danger since late September 2026. Gas is rising from the ground at multiple points in London Base, Uweye Quarter—inside compounds, around houses, and across farmlands. Water in low-lying spots and along roadsides bubbles. When residents test the gas on dry ground, it catches fire. Night photographs show open flames burning directly from the soil.
The Ovie of Uzere, His Royal Majesty Isaac Udogri I, described the scene on Independence Day. He said the community woke to “uncontrolled emissions of gas from the ground in countless places, including residential houses and farmlands, accompanied by open fire.” He warned that continued accumulation or spread could lead to a larger explosion and called on the federal and state governments to declare a state of emergency in Uzere. He also asked the National Oil Spill Detection and Response Agency (NOSDRA) and the Nigerian Upstream Petroleum Regulatory Commission (NUPRC) to send emergency teams immediately. Community vice-president Engr. Abednego Abugo called the event unprecedented and urged relocation of affected residents while experts assess the site. Former President-General Chief Emmanuel Ekebe noted that the nearest known pipelines lie about 300 to 400 metres away and were not operating at the time; the nearest Nigerian Gas Company line is also said to be non-functional. Residents have speculated that gas has built up underground and is seeking an escape route. As of mid-October 2026, the cause remains unestablished, and no public official statement has been issued by the operator of Oil Mining Lease 30, Heritage Energy Operational Services Limited (HEOSL), or by the principal regulators specifically addressing this seepage.
Why gas can appear where no active pipe is visible
The absence of an operating surface pipeline immediately beside the seeps does not rule out a petroleum-related source. In oil-producing areas, gas can migrate long distances through the subsurface. Possible pathways include:
- Compromised or abandoned wells (casing failures, unplugged annuli, or old wells whose integrity has degraded over decades). Gas under pressure can move upward and then laterally through permeable zones or fractures before emerging far from the original wellhead.
- Natural geological pathways—faults, fractures, or connected aquifers—that allow thermogenic gas from deeper hydrocarbon reservoirs to reach the surface. This mechanism has been advanced by NUPRC in the parallel Bille community gas seepage in Degema Local Government Area of Rivers State, where preliminary findings pointed to deep subsurface migration rather than failure of surface infrastructure.
- Pressure build-up from ongoing or recent well incidents that forces gas into surrounding formations.
Uzere has a long history of oil production under OML 30. Separately, Well 14 suffered a blowout on 26 June 2026 that continued to discharge crude oil and gas. On 17 August 2026, the Federal High Court in Port Harcourt (Suit No. FHC/PH/CS/132/2026) ordered HEOSL and NOSDRA to halt the discharge, begin remediation, and file a compliance report within 14 days. The current ground seepage at London Base is reported as a distinct event, but the two incidents share the same operator, the same lease, and the same community. Without isotopic gas fingerprinting, well-integrity surveys, and geophysical mapping, it is not possible to confirm or exclude a link.
Environmental and health effects
Natural gas is primarily methane. In high concentrations it is asphyxiating, highly flammable, and a potent greenhouse gas. Open flames already observed on the ground demonstrate the immediate fire and explosion hazard. Prolonged seepage can contaminate soil and shallow groundwater. In the Bille case, sampling detected methane, hydrogen sulphide, carbon dioxide and other compounds associated with respiratory irritation, neurological effects, and longer-term toxic risks; similar gases cannot be ruled out in Uzere until laboratory analysis is done. Farmlands are already affected, threatening livelihoods. Continuous bubbling and gas pressure also degrade water quality for domestic use. These impacts are consistent with documented effects of stray or fugitive gas migration in oil and gas settings worldwide: fire risk, aquifer contamination, and chronic exposure concerns.
Standard response expected in such cases
Nigeria’s framework, anchored in the NOSDRA Act and the National Oil Spill Contingency Plan, plus NUPRC’s upstream regulatory role and the Petroleum Industry Act’s host-community provisions, contemplates the following sequence for an uncontrolled gas release:
- Immediate public-safety measures: restrict access, remove ignition sources, establish continuous gas monitoring (lower explosive limit, methane, and hydrogen sulphide), and relocate residents from high-risk zones if concentrations or flame presence warrant it.
- Joint Investigation Visit involving NOSDRA, NUPRC, the operator, the state environment ministry, and community representatives. This should include gas sampling, isotopic analysis to determine origin (thermogenic versus biogenic), geophysical surveys, and inspection of nearby wells (including abandoned or suspended ones).
- Source control and containment once the pathway is identified—well intervention if a casing or annulus is implicated, pressure management, or sealing of surface seeps.
- Environmental assessment of soil, surface water, and groundwater, followed by remediation plans.
- Humanitarian support: safe drinking water, medical surveillance for affected residents, and temporary shelter if evacuation is required.
- Transparent public reporting of findings and timelines.
In the Bille seepage, federal officials visited, samples were taken, relief materials were supplied, and further international technical studies were commissioned—although lawmakers later criticised the pace. That sequence has not yet been publicly confirmed for Uzere’s London Base seepage.
Government and operator response to date
As of 15 October 2026—more than two weeks after the seepage was first widely reported—no public statement, site visit, or deployment of emergency teams by NOSDRA, NUPRC, or the Delta State Government specifically addressing the Uzere ground gas has been documented in available reports. The Ovie’s call for a state of emergency and immediate regulatory deployment remains unanswered in the public record. By contrast, Governor Sheriff Oborevwori inspected a Heritage Energy pipeline spill at Odidi in Warri South-West and directed relief and healthcare measures there. The August court order on Well 14 exists, but public confirmation of full compliance and remediation progress is limited. Community leaders have noted the absence of meaningful relief or corporate social responsibility linked to the earlier blowout.
The situation is therefore unsatisfactory relative to the reported severity—open flames in residential areas, spreading seepage, and an explicit royal call for emergency intervention. A parallel case in Rivers State drew federal ministerial attention and regulatory investigation even when the preliminary scientific view pointed away from surface infrastructure. Uzere has not yet received equivalent visible action.
What is needed now
Independent gas sampling and isotopic fingerprinting, a full well-integrity audit of OML 30 assets in and near Uzere (including abandoned wells), continuous air and groundwater monitoring, and a clear public timeline from NOSDRA and NUPRC. Until those steps occur, residents remain exposed to an unquantified explosion risk and potential contamination of land and water. The Isoko Nation, and Uzere in particular, has hosted oil production for decades. An unexplained gas eruption from the ground tests whether the regulatory and corporate response architecture can match the scale of the hazard it was designed to address.
Isoko Nation will continue to follow developments and publish verified updates as they become available. Residents and community leaders with documented observations or official correspondence are invited to share them with
