Sand production from the reservoir is caused by the structural failure of borehole wall rock. The internal causes of sand production from the reservoir are the stress state of borehole wall rock and the tensile strength of rock (affected chiefly by consolidation strength of rock), whereas external causes are the producing pressure drawdown value and the change in reservoir fluid pressure.
2016-1-8 This chapter analyzes mechanism and factors influencing sand production. The reason for sand production by oil wells is that the original pressure balance around the wellbore is broken, resulting in yielding and original structure failure of formation rock. The mechanism of rock failure includes mechanical failure and chemical failure.

2013-3-1 On the other side, the production of sand from crushed stone (artificial sand) has been conducted for over a decade by vertical shaft impactors (VSIs). This equipment consists of a rotor revolving at high speed. The rotor centrifugally throws the material into the crushing chamber where the comminution occurs by rock-on-rock impact, attrition
2019-8-1 The conditions for sand production depend on stresses and properties of rock and fluid. Accurate sand volume estimation is, however, still a challenging
2020-3-1 Sand production is worldwide problem. It always has significant consequences on field development. Sand production from unconsolidated formation reservoir is a very challenging issue as it ends the production life of a reservoir and well. In the oil and gas industry, millions of dollars are spent yearly for the cleaning of sand.

2001-1-1 Sand and gravel production in 1959 was 67% of the total with crushed rock providing the balance of 33%. By 1998 this situation had changed significantly with crushed rock production increasing substantially to 132 million tonnes (60%) and sand and gravel only to 86 million tonnes (40%).

2020-4-1 The rate of sand production then drops rapidly due to the dramatic decrease of the water production rate, which is less than 2 m 3 /d after 10 days of production. After that, the sand production is almost halted after 1 month of production. It is worth noting that most of the sands are produced in the early 10 days after well startup.

A novel aggregate (RPA) comprising recycled plastic was developed. The aggregate produced was lightweight, with a density ranging from 510 to 750 k kg / m 3 and absorption of from 2.7 to 9.81%. Other properties were comparable to aggregates of similar densities.
2017-6-22 Today, as mentioned before, aggregate production and recycling are defined in the form of crushing and in the central and the mobile plant types. In this research, with regard to the large-scale proposed recycling plan for Iran, only is the central type (fixed) considered. NA production (the first scenario) consists of three stages.
2021-1-25 Apart from aiding the environment, exploitation of recycled concrete aggregate (RCA) as a potential substitute for natural aggregates (NA) contributes to a framework of sustainable development as well as helps in maintaining an ecological balance by avoiding fast depletion of natural resources of aggregates.

2006-1-1 Paint. Paint is a significant market for kaolin, although it is considerably less than the market for paper coating and filling. About 600,000 tons annually are used worldwide as extender pigments in paint. The largest use is as a pigment extender in water-based interior latex paints. It is also used in oil-based exterior industrial primers.
The production of a mechanochemical activated kaolinite can receive great attention in concrete industry, only if this activation is also chemical, and if it could be translated to pozzolanic activity. The mechanical activation of kaolinite is considered as mechanochemical, and it is possible to obtain an active pozzolan with the activity

2019-10-29 Paint waste sludge (PWS) is one of the most polluted wastes of automobile construction industry. The main objective of this study was the experimental control of the neutralization of hazardous PWS (up to 20 wt%) in kaolin clay composites during the sintering of their mixtures at temperatures of 1000 °C, 1050 °C, 1100 °C, 1150 °C, 1200 °C, 1250 °C, and 1300 °C in order to manufacture
Some kaolinite is produced by the in situ hydrothermal alteration of feldspar in granites, as for example that of south-west England. Kaolinite may then be reworked from such a source, and re-deposited in lacustrine environments, as for example the Oligocene ‘Ball Clay’ deposits of Bovey Tracey, Devon.
