Oceanus conducts Environmental Analyzes offering solutions for Environmental Consultancy companies, Industries, Sanitation Companies, Industrial and domestic landfills and Commercial Enterprises in several matrices.

HCS – Hidrocarbon Solutions, a company of the Oceanus group, carries out detailed analyzes to characterize Organic Geochemistry of Oils, Generating Rocks, Sediments and Soil, being an important tool for understanding petroleum systems and environmental monitoring (Hopanos and Esteranos).


Surface Waters

Oceanus performs the most diverse laboratory analyzes in surface waters (rivers, lagoons, springs, bathing and sea), such as: physical-chemical, metal, microbiological and organic analyzes. Compliance with CONAMA 357/2005

The analysis methodologies are based on EPA – Environmental Protection Agency, SMWW – Standard Methods for The Examination as Water and Wastewater, CETESB and ABNT.


In order to assess the contamination of degraded areas and their impact on neighboring aquifers, groundwater monitoring is necessary to verify the impact generated and which may influence neighboring communities. Through the analysis of some parameters, we can assess their maximum exposure limits, the degree of risk and toxicity by comparing them with the CONAMA 420 resolution. within the limits of CONAMA 396. Our technical team is qualified to serve you in the best way, from sampling to interpretation of analytical data.

Industrial Effluents

The effluents are analyzed in order to verify the efficiency of the wastewater treatment, in order to avoid the pollution of the water bodies so that the evaluated parameters are framed in the maximum values ​​allowed by the legislation. Among the analyzes we can mention the study of process treatability, characterization of the effluent, analysis of sanitary and industrial sewage and monitoring of Treatment Plants.

Water for Human Consumption

Potability – In order to test the quality of the water we drink, that is, its potability, several physical-chemical and microbiological parameters must be evaluated. Acceptable standards for these parameters and / or contaminants are given by the Consolidated Ordinance of the Ministry of Health No. 5/2017.

Mineral Water and Ice – Likewise, we have standards for the consumption of mineral water and ice commercialized on the market, where quality assurance requires frequent monitoring following the guidelines of RDC 274 and RDC 275 of ANVISA.

Purified Water – In addition to potability, the quality of the water in the manufacturing process of pharmaceutical consumer products has a purification criterion that must be proven through a chemical and microbiological analysis report, according to Brazilian Pharmacopoeia and USP 37.

Reuse water: Compliance with ABNT NBR 15527/2007 and ABNT NBR 13969/1997 standards

Solid Waste

In compliance with ABNT 10.004, 10.005, 10.006 and 10.007, the analysis of solid waste is applied in order to characterize and classify them with the purpose of knowing the correct way for the correct destination in the specific type of landfill, or the use of it in some industrial processes.

Biological and Microbiological

The monitoring of physical-chemical parameters does not always report the reality of the environmental impacts generated by chemical contaminants released into nature. In this sense, the monitoring of live species can sustain in a more concrete and representative way the environmental impact generated.

Air Quality and Atmospheric Emissions

Our laboratory has a team specialized in assessing and monitoring atmospheric emissions and assessing air quality in compliance with the CONAMA 001/1990, 008/1990, 382/2006, 436/2011 and 491/2018 legislation to meet the following demand:

Air quality monitoring
Sampling of atmospheric emissions
Environmental noise assessment
Process efficiency



The headspace name designates the space between the solid or liquid portion and the lid of a container. Headspace analysis is used for the analysis of free gaseous hydrocarbons (C1-C6 +) in soil / sediment samples.



Isotopes (to consult)


Biomarkers are complex organic compounds, “molecular fossils”, which show little or no change in the structure inherited from the original organic molecules, producing more stable saturated compounds, preserved in geological samples. These compounds represent a small fraction of the oil, but are of great importance, as they allow the correlation between the oil and the generating rock, the assessment of the degree of thermal evolution, the depositional environment of organic matter and the level of biodegradation in which the oil was subject.

SARA (Fractionation)




The characterization of biomarkers in rocks through studies in rock extracts can contribute significantly to the knowledge of chemical transformations in the organic structures present in biogenic precursors, associated with the processes of fossilization of organic matter. The assessment of the generating potential of a rocky outcrop, using the techniques of total organic carbon and pyrolysis, allows quantifying the organic carbon and characterizing the type of organic matter, estimating the type of product to be generated.

Surface Geochemistry and Piston Core

Oil research is a complex activity that requires multidisciplinary teams and the use of different technologies. In exploratory frontier areas, an oil or gas discovery can rarely be credited to the use of a single tool, but it results from different contributions that complement and continually improve.

The Surface geochemical prospecting method (Onshore) and Piston Core (Offshore) consists of the detection of gaseous hydrocarbon micro-exudations in soil / sediment samples and is used as a support tool for oil exploration, providing a better assessment of the petroleum potential of terrestrial sedimentary basins, allowing a more careful analysis of exploratory risk.

Oil Spin

The basic principle of forensic geochemistry is the irrefutable fact that any type of contact leaves a trail. There is evidence that can characterize those responsible for a spill in the event that an oil reservoir vessel or platform suffers a collision or presents a leak in the pipeline.

To correlate the spilled oil, it is necessary to characterize the organic content, separating the contribution of particulate and molecular organic components (contaminants), and to quantify the contamination by oil and its derivatives.

The samples must be analyzed to study the quantification and qualification of contamination by oil and its derivatives using petroleum geochemistry techniques.
