What We Do

Environmental Impact Assessment, Laboratory and Remediation Services in Nigeria

Quatenary's services are organised into four strategic business units, backed by a wider set of oil & gas field capabilities. Fieldwork and accredited laboratory analysis are delivered under one roof — whatever a regulator or a project asks for, this is what we do.

Environmental Services

Full studies planned, executed and defended through regulatory review — fieldwork, stakeholder engagement, reporting and approvals.

EIA
Environmental Impact Assessment
ESI
Environmental Sensitivity Index mapping
PIA
Post Impact Assessment
ECM
Environmental Compliance Monitoring
EES
Environmental Evaluation Study
PCI
Post-project Completion Inspection

Every study is delivered within the regulatory framework of NUPRC, NMDPRA, NOSDRA and the Federal Ministry of Environment, with the field data and laboratory results needed to defend it through review.

Laboratory Services

Environmental and bio-monitoring laboratory analysis by experienced analysts using modern instrumentation — with results you can put in front of a regulator.

  • Soil
  • Water & sediment
  • Drilling mud & cuttings
  • Petroleum products

Spill Clean-Up & Remediation

Clean-up and remediation of hydrocarbon-impacted areas onshore and offshore, including Remediation by Enhanced Natural Attenuation (RENA) and phytoplankton studies.

  • Onshore & offshore
  • RENA
  • Phytoplankton studies

Geotechnical & Geophysical

Geotechnical and geophysical investigation, seabed survey and water-resources studies that give a project ground truth before it builds.

  • Geotechnical
  • Geophysical survey
  • Seabed survey

Specialist Capabilities

Beyond the Four Business Units

Field and support capabilities we deliver alongside the core environmental and laboratory work — often on the same site, under the same contract.

Air Quality & Noise Monitoring

Ambient air quality sampling and noise-level monitoring, modelling and mapping — for baseline studies and ongoing compliance.

Hydrogeology & Groundwater

Hydrogeological studies, groundwater monitoring and water-resources assessment — hydraulics and salt-water intrusion control.

Environmental Auditing & Consulting

Environmental audits, pollution control and strategic sustainability advisory across industries.

Marine Logistics

Tugboats and barges, towage and wreck removal, shore protection, offshore support vessels and jetty piling.

NORM Measurement

Measurement of Naturally Occurring Radioactive Materials on used pipes, christmas trees and other waste streams.

Strategic Procurement

Global technology and material sourcing, quality assurance and control, supply-chain management and warehousing.

Construction & Installation

Pipeline installation, onshore and offshore facilities, instrumentation, control systems and front-end engineering.

Equipment Leasing

Leasing of specialist environmental and field equipment, with manpower support for start-up operations.
