Petroleum Engineering

The core analysis and oil & gas testing laboratory was found in 2007, which provides oil & gas industry with services of conventional and special core analysis, fluid analysis and evaluation, comprehensive physical research on reservoir, reservoir engineering proposal, reservoir description, stimulation treatment on oil & gas field and reservoir management, as well as helps users improve the development effect on reservoir and enhance the hydrocarbon recovery. The specific services are as follows:

1. field services for well site

1) Oil & gas analysis: The on-site oil & gas measurement should be taken regularly, including the analysis on chemical and physical constitution and property of formation water, the analysis on hydrocarbon constitution and chemical and physical property as well as the detection and analysis on CO2. H2S and other compositions

2) Surface oil & gas sampling: The sample of oil & gas is collected by using high pressure gas bottle of all kinds of models from well head, separator and other process equipments, the authentication services of samples are also provided

3) Well sampling: the professional well sampling group and equipments as well as the sampling services of oil & gas single-phase well hole are all supplied

4) Water analysis: the analysis on produced water is mainly used to ensure the component and origin of liquid, including: Ca²+, CL-, Mg2+,Ba2+, HCO3-, S2-, SO4-, Fe and the concentration, PH, resistivity and fluid density of other ions
