lABORATORY SERVICES-Oil, Gas & Produced Waters

Oil, Gas & Produced Waters

California drilling operations and oil production are concentrated primarily in Kern County, San Joaquin Valley and the Los Angeles basin. There is also some offshore oil and gas production in California, but there is now a permanent moratorium on new offshore oil and gas leasing and new offshore platforms in both California and federal waters. Widely distributed in sedimentary basins of southern California is the Monterey shale.

OEC is the leading regional provider of sampling, field testing and lab services for the oil & gas production industry.  Our services are performed by experienced field and lab employees and support the needs of all Upstream, Midstream and Downstream operations.

Green House Gas Emission Testing

OEC provides all necessary sampling and testing services required to comply with 40 CFR Part 98, Subpart W and the Greenhouse Gas (GHG) Emissions Testing for the ARB Mandatory Reporting Regulation for Petroleum and Natural Gas Systems.



Heavy Oil Sample Collection Procedure

Draft Sampling & Testing Method: Flash (Liberation) Protocol, Air Resources Board Draft Test Procedure for Flash Emissions of Green House Gases and Other Compounds from Crude Oil and Natural Gas Separator and Tank Systems

Petroleum and Oil

Petroleum and Oil contamination becomes unsuitable from its original purpose due to the presence of impurities or loss of original properties. OEC follows protocols set by EPA (Environmental Protection Agency),  ASTM (American Society for Testing and Materials),  LBNL/WSPA (Lawrence Berkeley National Laboratory / Western States Petroleum Association), SCAQMD (South Coast Air Quality Management District),  and RSK-175 (CO2,CH3, O2, H2S) for Petroleum and Oil.


Gas and Vapor

Substantial quantities of toxic and non-toxic waste are generated during the extraction, refinement, and transportation stages of oil and gas. Some industry by-products, such as volatile organic compounds, nitrogen & sulfur compounds, and spilled oil can pollute air, water, and soil at levels that are harmful to life where improperly managed. OEC follows protocols set by EPA (Environmental Protection Agency) and ASTM (American Society for Testing and Materials) for Gas and Vapor.


Water Geochemistry and Geochemical

The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapors from the contaminants, or from secondary contamination of water supplies within and underlying the soil. OEC follows protocols set by EPA (Environmental Protection Agency), ASTM (American Society for Testing and Materials), SM (Standard Methods for the Examination of Water and Wastewater) for Water Geochemistry and Geochemical.

Natural Gas Liquids

Natural-gas condensate, also called natural gas liquids, is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. Some gas species within the raw natural gas will condense to a liquid state if the temperature is reduced to below the hydrocarbon dew point temperature at a set pressure. OEC follows protocols set by EPA (Environmental Protection Agency), ASTM (American Society for Testing and Materials) for Natural Gas Liquids.
