This research work discusses the feasibility of polyacrylamide-grafted-polyethylene glycol/SiO 2 nanocomposite as a potential additive for the drilling of troublesome shale formations which may lead to severe wellbore instability problems. The free radical polymerization technique was adopted for the synthesis of the nanocomposite and it was characterized by Fourier transform infrared
Polyacrylamide as an agglomeration additive for copper
1. Introduction. Heap leaching is a method used to recover precious metals such as gold and copper from low grade ores. In copper heap leaching, the ore is stacked in approximately 6.1 m (20 ft) ‘lifts’ and an acidic leach solution (raffinate) is sprayed on the top of the heap.

A study of uranium-ore agglomeration parameters and their
1. Introduction. The agglomeration process represents a way used by nickel, copper and uranium industries to enhance acid heap leaching of low grade ores containing large amount of fines and clays (Dhawan et al., 2013).This industrial technology consists in increasing ore particle size distribution by gathering fines to improve the heap permeability and stability and also prevent fine particle

CN102428157B - The water-soluble polymers of single mixed
Be suitable for the composition based on anionic polymer or water-soluble bisexual copolymer (multipolymer) that oil recovery injects fluid thickening, it is characterized in that, before with the dilution of injection fluid, it is also selected from the stablizer of deoxygenation reductive agent, precipitation agent, free-radical scavengers, complexing agent and sacrifice agent containing at ...
INTRODUCTION. Polymeric insulators have started replacing glass and ceramic insulators since 1940s because of the superior characteristics of the polymers over ceramics such as light weight, excellent insulation, simple installation and transportation, and outstanding mechanical, thermal, and electrical properties 1.Polymeric insulators consist of two components, that is, the core made of a
IOP Conference Series: Materials Science and Engineering
The article discusses the problems of providing energy supply to consumers in remote regions of Russia, including in the Arctic zone. The necessity of introducing and developing the best available technologies for autonomous energy supply to consumers in the decentralized electricity supply zone, which should be based on the combined use of technologies and reducing cross-subsidization for the
Malaysia is a well-endowed country with oil palm and is the second largest producer after Indonesia, contributing more than 80% of the world production [3]. Oil palm is the most cultivated plant in Malaysia, with approximately 5.4 million hectares of plantation area and about 423 palm oil
High-Temperature Core Flood Investigation of Nanocellulose
Recent studies have discovered a substantial viscosity increase of aqueous cellulose nanocrystal (CNC) dispersions upon heat aging at temperatures above 90 °C. This distinct change in material properties at very low concentrations in water has been proposed as an active mechanism for enhanced oil recovery (EOR), as highly viscous fluid may improve macroscopic sweep efficiencies and
