Title

THE EFFECT OF OIL EMPLACEMENT IN CEMENTATION PROCESS IN THE ASMARI RESERVOIR'S SANDSTONES- HORIZONS, MANSURI OIL-FIELD

Pages

  60-73

Abstract

 The sandstone zones of the ASMARI RESERVOIR in the Mansuri oil-field have occurred in 2, 3, 4, and 5 of reservoir zones. The first two of these units are the main horizons of sand problems due to weak/lack of CEMENTATION or loose particles. In the present study, these zones were studied and evaluated on the basis of WELL LOGS, thin sections and also petrophysical data. The results showed that less CEMENTATION phenomenon and sand problems are present in the central and eastern parts of the field, especially in the upper part of zone 2. On the other hand, CEMENTATION and cohesiveness of grains increase toward the water-oil contact. On the basis of petrographical studies, it is clear that the ASMARI RESERVOIR sandstone horizons mineralogically consist of quartz, calcite, dolomite, anhydrite, and gypsum. The sorting of the particles is weak to intermediate. The results of this study indicate that one of the most important reasons for lack of CEMENTATION is the hydrocarbon migration and its emplacement in sandstone horizons of the ASMARI RESERVOIR. Because the relative permeability of the pore water is decreased, due to the emplacement of hydrocarbon, the rate of CEMENTATION will be reduced. In addition, the lithological variation and its distribution is an important controlling factor.
