The methodological issues of estimating the volume of associated petroleum gas flaring in oil fields using medium resolution satellite images are considered. The importance of such estimation is related not only with the possibility of organizing operational monitoring of flared gas volumes in oil-producing areas but also with the need to assess the contribution to the global greenhouse effect of carbon dioxide emissions into atmosphere during associated gas flaring. The previously developed method based on the use of the normalized heat point index proposed by the authors was used for determining the number of flare units in the territory using Landsat-8 satellite images. Using the official data on the total associated gas flaring volumes in the Khanty-Mansiysk Autonomous Okrug and on the number of flare units in this area, determined from satellite images, an equation has been proposed that allows calculating the expected volumes of gas flaring depending on the number of flare units operating in the territory. An analysis of the developed model error for estimating the total quarterly volumes of gas flaring based on the data on the number of flare units in the oil production area is carried out. It is shown that this error does not exceed 10 % on average. The model can be used in space monitoring of gas flaring volumes using Landsat-8 satellite images.
Keywords: flare installations, space images. satellite monitoring, associated petroleum gas, gas burning in oil fields, normalized index of heat points, greenhouse effect
