P022 CONDITIONS OF FORMING STRATIGRAPHICALLY TRAPPED RESERVOIRS CLINOFORM COMPLEX WESTERN SIBERIA Summary 1 The Neocomian sandstone reservoirs in the western Siberia basins occur mainly in turbidity fan related to progradational clinoforms. The most prospective reservoirs were deposited by grain flows during regression and subsequently reworked by along-slope bottom currents. These reservoirs form stratigraphic traps due to updip pinchout within the clinoforms. Based on this model 26 most favorable areas were mapped out by geophysical data for detailed exploration. First-pass ranking for exploration potential is based on those factors controlling a reservoir capacity greater than 8 % porosity similar to that
