Who We Are

A Multidisciplinary Environmental Partner, Owned and Run in Nigeria

Quatenary International Company Limited was incorporated in 2007 as an environmental and laboratory firm, and has grown into a multidisciplinary services company working from Warri, Delta State — at the centre of the region we know best. We render quality environmental, laboratory and field services to national and international operators across the oil and gas industry.

We are equipped with a consortium of highly skilled and experienced professionals dedicated to innovation, and we are deliberately client-centred. Every engagement starts with your regulatory position and your deadlines — with fieldwork and accredited laboratory analysis delivered under one roof.

Our own laboratory

Fieldwork and an in-house environmental & bio-monitoring lab under one roof — no sub-contracting, and results defensible before a regulator.

Since 2007, on the hardest sites

Nearly two decades delivering for NNPC, Shell, Nigeria LNG, TotalEnergies, Seplat and other operators across the Niger Delta.

What We Do

Four Strategic Business Units

Quatenary's services are organised into four strategic business units, backed by a wider set of oil & gas field capabilities. Whatever a regulator or a project asks for, this is what we do.

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

Plus baseline studies, toxicity testing, and two long-standing specialisms — air quality & noise monitoring and hydrogeological & groundwater studies — detailed below.

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

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
