Development of structural analysis methods as a part of remaining oil reserves localization

Authors: L.S. Brilliant, M.A. Antipin, O.Yu. Myasoedova (Tyumen Oil and Gas Institute JSC)
Methods of structural analysis were investigated to identify local structural variations in the oil reservoir, including variations probably characterized by higher oil saturation and feasible for further development. Results of signal analysis research methods developed by Tyumen Oil and Gas Institute JSC within the last five-year period are presented. Three methods are described: moving average method, differential moving average method and wavelet decomposition. Also the mathematical foundations of methods are presented. 
Keywords: the structural analysis, the vejvlet-analysis, a trend, a trend surface.
