Laboratory Services
Lab ServicesTETRA provides a full array of API approved laboratory services to complement our production testing operations. Our lab technicians utilize state-of-the-art equipment for analyzing natural gas, liquid petroleum, and oil field waters.

During the testing process, samples of the effluent stream are retrieved from the test separator and taken to TETRA’s laboratory facilities where they are analyzed for content.

 

AVAILABLE SERVICES

 

ASTM Analysis
TETRA provides ASTM D-86 distillation analysis of liquid petroleum. This analysis provides the percent recovery and temperature profile of the distillate. The ASTM D-86 analysis also includes measurement of API gravity at 60F.

Gas Composition Analysis
Gas chromatography is used to determine the composition of natural gas from methane through C6+, including carbon dioxide and nitrogen. This analysis includes the specific gravity and both dry and wet BTU values.

Oilfield Water Analysis
For oilfield water analysis, TETRA utilizes a spectrophotometry, titration, and other analytical methods to determine:
  • Barium Content,
  • Calcium Content,
  • Chloride,
  • Iron,
  • Magnesium,
  • Potassium,
  • Sodium, and
  • Sulfate.

The oilfield water analysis also determines:

  • Alkalinity Information,
  • Conductivity and Resistivity Information,
  • pH Level,
  • Specific Gravity, and
  • Total Dissolved Solids.

In addition to the above information, a Stiff-Davis Saturation Index is also provided that predicts the scale forming tendency of the sample.
