Oil and Gas Section

The Oil and Gas Section makes its services available to the petroleum industry and private individuals seeking verification of crude oil/gas seeps sources or requiring specific and detailed analyses for characterization and evaluation purposes.

We also conduct analyses of Bio-fuel samples to check compliance to parameters set by Philippine National Standard (PNS) on these samples.
