Oil Shale is one of the unconventional energy which is to be one of the main topic related to study and research almost all over the world for the development, exploration, and exploitation as a source of energy instead of fossil fuels.
In-situ retorting is a method used in the exploration and exploitation of oil shale especially below the surface. The depth of the source of oil shale ranges between two hundred until two thousand meter, from the depths, allows retorting in temperature four hundred until six hundred degree celcius and an injection of compound a chemical in the process of in-situ retorting may cause negative impacts on the surrounding environment. Contamination of groundwater is one of the environmental impacts that could occur in the process of in-situ retorting. The method in this research is a literature study on the exploration and exploitation of oil and shale relation to the quality of the surrounding environment.
This research will discuss the improvement of environmental quality in the exploration or exploitation of oil shale, especially in maintaining the quality of the groundwater resources around the activity of exploration and exploitation. In the end, the result expected that production and environmental sustainability can go together and in harmony.
