Oil and natural gas are the most important mineral resources in Tripura. Other minerals of significance are glass sand, plastic clay, shale and sand for building/construction. ONGC carried out seismic geophysical surveys and 15590 meter drilling (Including Mizoram) for petroleum and natural gas exploration in the state.
The value of mineral production in 1994-95 at Rs. 11 crore decreased by 5% compared to the previous year. Natural gas was the only major mineral produced in the state, the output of which decreased by 5%.
