The fine particles have significant influence for sand control mode selection. According to investigation and analysis, we learn that the gravel packing has been used widespread in sand control when the contents of fine particles are high. Based on designing the pre-packed screen, different fine particles sand control research is …

1 INTRODUCTION. Historical remnants have proven that as early as 10,000 B.C., the Natufians recognized how to accelerate the beer brewing process by grinding cereals into smaller particulates with long wooden pestles in gigantic rock mortars. [] This indicates that the long history of exploiting fine particulates can be traced back to the …
