Many of the companies in the oil gas industry are trying their best to introduce the environmental friendly technologies so that the production efficiency of the energy can be improved and thereby the environmental protection purpose can be achieved.

Billions of dollars have been invested into the design of new devices to have the oil extraction and there are a lot of companies which are trying their best to make sure that the oil extraction process would not affect the environment.
