Background: Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production. Objective: This paper presents a sand content computation model for the crude oil, which uses the power of sand production and Parseval theorem,...

Many different types of surface mining equipment use enclosed cabs to protect equipment operators from health and safety hazards. The overburden removal and mining process can be extremely dusty and can cause excessive dust exposure. To study this issue, a cooperative research effort was established between the National Institute for Occupational Safety and Health, U.S. Silica Co., Clean Air Fi...

Saltation is an important geological process and the primary source of atmospheric mineral dust aerosols. Unfortunately, no studies to date have been able to precisely reproduce the saltation process because of the simplified theoretical models used. For example, sand particles in most of the existing wind sand movement models are considered to be spherical, the effects of the sand shape on the...

The Exploration, construction, mining, management, refining, transportation, and sales of C sand mining in the Bõne Regency development liars harms environment community morals are all part frameworks research, exploitation. number illegal operations increased from 2013 to 2015 despite efforts by Regency's legal authorities eradicate it. In several instances Regency, there was no procedure. ord...

‘Reservoir Characterization (RC)’ can be defined as the act of building a reservoir model that incorporates all the characteristics of the reservoir that are pertinent to its ability to store hydrocarbons and also to produce them. It is a difficult problem due to non-linear and heterogeneous subsurface properties and associated with a number of complex tasks such as data fusion, data mining, fo...

Abstract Taking the sand mining project in a local river section lower reaches of Yangtze River, as an example, this paper investigates complex effects on potential. Based MIKE21 software to establish two-dimensional water–sand mathematical model section, study change potential near after implementation different schemes through numerical simulation explore influence The results show that (1) e...

Unlike green sand, chemically bonded sand cannot be used again and again without reclamation because in this system, the mixed sand gets it`s strength through chemical reaction which is irreversible in nature. Each sand particle is coated with this reacted chemical, which behaves like an inert element after usage once. This inert coating also called “Dead” binder needs to be removed from the us...
