Print this pageAbstract: Quantitative Forecast of Petroleum Potential from Space Image Interpretation Data (with Reference to the Precaspian Petroliferous Basin)
ANTSYFOROV, ALEXANDER I. and GOLOVCHENKO, YURI V
The forecast is made using a special space image interpretation technique enabling acquisition of data comparable with those obtained by petroleum exploration at the object size evaluation phase. This positive neotectonic structure controlling petroleum accumulation, recognized on space images, provide the basis for petroleum zoning using space images (hereafter zoning). Areal zoning elements correlated with petroleum-based sequence subdivision characterize the accumulation potential of the objects of forecast. The accumulation potential of each zoning element is estimated in terms of HC resource density per unit rock volume following the sequential approximation principle, according to which the resource concentration estimates are gradually improved in the sequence of objects from a petroliferous basin (regional resource density) to a petroleum accumulation zone (zonal density). The regional resource density is calculated using regression equations defined according to training samples from structurally different basins. The accumulation potential of petroleum accumulation zones is largely represented by the resources concentrated in anticlines expressed as isolated photogeologic anomalies. Zonal resource density estimate is based on the discovered mathematical relationship between the reserves in productive anticlines and the areas of the according photogeologic anomalies. The technology was tested in a number of standard areas. The results are comparable in accuracy with conventional resource estimates but offer considerable time and money savings.
