·Therefore sand production can occur when the rock deforms because of in situ stresses related to reservoir depletion which causes effective stresses to surpass the formation strength Aminu et al 2019a Consider a rock formation as a cage that encloses individual sand grains While the fluids in the pores push outward against the cage walls
The paper discusses sand production from oilfield chemicals rock interactions models that are used to forecast sand production personnel safety and maintaining production facilities
·A model for global supply of sand gravel and cut stone for construction based on a system dynamics model was developed for inclusion in the WORLD6 model The Sand Gravel Stone model simulates production and market supply demand and price for natural sand and gravel sand and gravel from crushed rock and cut stone The model uses market
·Sand production on crystalline domes results from rock weathering on slightly convex summits as well as on steep side flanks 55 60° slope Sliding and falling of curved rock slabs upon exfoliation and splitting expose ledges on lateral cliffs and pseudokarstic alveoles Physical weathering disintegrates the rock into white sands
·The results of sand production prediction indicated that sand production from rock skeletons should never appear but the rock skeletons was observed in the sand samples and thus the impact of salt precipitation was taken into account The experiments proved salt precipitation caused a degradation in rock strength and the difference between
·Mineral processing has been long applied to CDW recycling although few researches focus on the production of recycled sand The sand fraction originally present in crushed C&D waste represents around 50% of the total waste This paper presents a technology that permits the production of high quality recycled sand The total comminution of C&D waste
·Granite rock sand usually has fineness modulus of Zhou et al 2008 found that it is Dolomite rock sand has a higher range of fineness modulus which implies coarseness than other CRS Katz and Baum 2006; Wang et al 2014; Cepuritis et al 2015 Average percentage of fine content is given in Table 4 Granite and
·This paper describes the application of Discrete Element Methods DEM [5 14 11 12] to model the mechanics of sand production in oil recovery processes Sand production occurs when a weak sandstone matrix disintegrates due to changes in fluid pressure gradient and/or effective stress To cite this paper Int J Rock Mech & Min Sci
