| Abstract |
| land subsidence risk assessment basically based on current information found that the analyzed subsidence districts are at over the top and medium hazard of tormented by subsidence resulted in damages like diminish in run-off and wastewater seepage capacity, disturbance to water transportation structures undermine artificial infrastructure balance. Also Land subsidence may also be caused by the exploitation of oil and gas. Russia is a major oil and gas producer in the globe. The Romashkino field is an oil and gas field located in Tatarstan, Russia. In 1948, the largest oil field in the Volga-Ural Basin was found there. In this study, we focus, application of INSAR analysis for surface deformation by oil and gas extraction and in-jection cycle with 14 SLC SAR Images of the descending pass from sentinel-1 satellite in C band between 2017 and 2020. The Permanent Scatterers (PS-InSAR) Technique was utilized to study dis-placement deformation utilizing the SARPROZ software. The PSI using inter-ferograms with a super master scene. In this approach, just the coherent pix-els with stable phase or amplitude are processed. due the high-density vege-tation cover and long winter time with snow cover decreased the number of resulting points. Result of the displacement re-sampled Price of local land deformation be-tween 2017 and 2020 projected. The displacement rates surrounding the Romashkino oilfield in this study range from 3 mm/yr to -9 mm/yr, accord-ing to PS-InSAR measurements. Additionally, we suggest an acceptable cut-off to choose the PSs for the case study when is > 0.70 (DA 0.25). |
