If the production velocity is sufficient to transport sand to the surface, the sand may still become trapped in the separator, heater treater, or production flowline. If enough sand becomes trapped in one of these areas, cleaning will be required to allow for efficient production of the well.
The advantages of using a silica substitute outweigh using silica in abrasive sandblasting. Any health issues and healthcare costs related to silica would be greatly reduced or eliminated. The time and cost of implementing and maintaining engineering controls would also be eliminated.

Silica sand contains 90% or more! During blasting the sand particles break down into very small particles. These particles, smaller than 5 microns, are inhaled and become embedded in the lung, causing respiratory problems, pulmonary silicosis (also called 'dust-lungs'), and eventually even death.
Can we use m-sand (crusher sand) for concrete instead of river sand? Home Construction Tips / 5 Comments Yes, M-Sand (crushed sand) can replace river sand in a concrete mix proportion.
This sand is very much useful for the construction purpose such as plastering and so on. Crushed Stone Sand/ Artificial Sand/ M Sand. It is a substitute for River Sand, it is also known as fine aggregates which is manufactured by crushing either granite or basalt rock using 3 stage crushing process by some companies.

Manufactured Sand (M-Sand) & Plaster Sand: Manufactured Sand is manufactured by proper crushing of aggregates into finer materials of required particle size (generally using VSI technology). Since quality control is maintained in the process of preparing manufactured sand, the sand obtained will better confirm to the Zone-II grading standards ...
Washed sand should be used at site for getting more strength in construction work. Bulking of Sand Due to moisture in each particle of sand, sand gets a coating of water due to surface tension which keeps the particles apart. This causes an increment in volume of sand known as Bulking.
Effect of Fineness of Sand on Density of Concrete After measuring the slump, several 150 mm cubes were filled. These were cured in water tank for 28 days. After curing, each cube was weighed using electronic balance and density of concrete was calculated. The variation of density with FM of sand is shown in Figure 3 for different cases.
