The remote thermal area monitoring of oil filds as a management tool of fild data process

The article is concerned with the opportunity analysis of the remote retrospective monitoring of thermodynamic and fluidodynamic field as the management tool of process control system of the oilfield at the late stage of field research. As the data source, multi-year data of spacebased and observer thermal imaging system of far infrared band (7.5-14 micron) are used. Field patterns of heat radiation of Yelabuga oilfield (micro- and cross-section aspect to a depth of 5 km as on 1988, 1999, 2014) are compared in the article.
Materials and methods
Ladsat thermal imaging of different years. The method of outer-space remote-action geothermal survey - map-making imitation of geothermal field and fluidodynamic systems.
Results
Pilot survey on the territory of the Yelabuga oilfield illustrated the efficiency of the method for complicated large-volume thermodynamic and fluidodynamic fields. The method can be considered as the essential part of the system (complex of methods) to control water flood influx on the territory of producing fields.
Сonclusions
• The abnormality of the thermal area exists up to the present moment, in spite of discharge pumping dozens mil of m3 of cold waters and drainage of the same volume of warm liquid from the interface №531. Lapse map of heat radiation, based on the microsection at the depth of 1500 m, composed according to the mapping, made in 2014 by applying Landsat-8, makes it absolutely clear. Discharge pumping and drainage from productive sediments changes the location of warm signature and its configuration.
• The Yelabuga oilfield of Devonian oil is concerned with the crystalline basement of fluid channel, where thermal convention horizontally upraises south easterly north-westward.
• Water-injection operation activates ascending waters out of the pattern from the Upper Devonian reservoir into upper hydrodynamic levels of water exchange.
• Post-event analysis and routine monitoring through the method of outer-space remoteaction geothermal survey, including the field data, can provide the dynamic picture of changes in structure of geothermal and fluid area in operation of field exploitation. This calls for data correlation, including oilfield data and outer-space thermal imaging.
