1 P583 USING IMAGE ANALYSIS TO QUANTIFY TEXTURAL CHANGES DUE TO POST- DEPOSITIONAL REMOBILIZATION OF FINE- GRAINED SANDS R. JONK D. DURANTI A. HURST and J. PARNELL Department of Geology and Petroleum Geology University of Aberdeen Aberdeen AB24 3UE UK Summary An image analysis method is used to describe textural changes caused by remobilization of very fine to medium grained sands. Image analysis on non-cemented injected sands shows that sands with high primary porosities (25-40%) get packed to give porosities below 20% due to remobilization. Calcite cementation in some reservoir-scale sandstone dykes causes them to loose any remaining porosity. Cementation
