The work is devoted to the presentation of methodological issues of the operational estimation of flaring volumes of associated petroleum gas in oil fields based on satellite images of medium resolution. The importance of estimating the amount of associated gas flaring is associated not only with the possibility of organizing the monitoring of the volumes of combusted gas in oil producing areas, but also with the need to assess the contribution to the global greenhouse effect of carbon dioxide and other greenhouse gases emitted into the atmosphere by associated gas flaring. Methodical issues of remote determination of the number of gas flares active in the oil production area from medium resolution satellite images are considered. The developed method for determining the number of flare units in the territory from the Landsat 8 satellite images is based on the modification of the known normalized burnt index. Using the official data on the total amount of burned associated gas in the Khanty-Mansiysk Autonomous Okrug and the number of gas flares in this area, determined from the satellite images, a regression model has been constructed that allows calculating the volume of gas combustion depending on the number of operating flares in the territory. The error of the developed model for estimating the volumes of gas combustion from the data on the number of flare units in the oil production area is analyzed. The model can be used in the tasks of satellite monitoring of volumes of combusted gas using Landsat satellite imagery.
Keywords: gas flare, Landsat 8, associated petroleum gas, gas combustion in fields, greenhouse effect, oil and gas producing areas
