Executive Summary : | It is of ongoing concern that continuous on-shore oil and gas extraction as well as groundwater mining in the area, may contribute to the subsidence of the Mehsana Block of North Cambay basin. Our project will investigate land subsidence in the exploration oilfields due to hydrocarbon extraction in the Mehsana Block of ONGC and land subsidence in the Mehsana basin due to groundwater withdrawal in the region. Land subsidence will be investigated using DInSAR time series to map the land subsidence and to confirm the deformation source. Modelling of land subsidence in relation to groundwater withdrawal and petroleum extraction and consequent mass deficit will help to simulate future land subsidence scenario and to recommend preventive measures. |
