Reduction in Stress Distribution in Horizontal Well Cementing
Abstract: Abstract: This paper addresses the stress distribution problem and effect on the cement behind the casing in the horizontal wells. The uneven stress distribution in the horizontal well causes crakes and breakage of the concrete which leads to various problems like instability of the bore hole in the affected region and secondly it paves path for flow of unwanted fluids in the cemented channels. Hence, to neglect this kind of …

Pickering asphalt-water emulsions stabilized by polystyrene nanoparticles obtained from recycled material
Abstract: In recent years, emulsified asphalt has been found to offer numerous advantages over conventional asphalt. More recently still, emulsified asphalt stabilized with nanoparticles has emerged as an option for the construction field because this substance has many advantages over traditional emulsified asphalt, which is formulated with surfactants that tend to be less stable and more toxic. These new formulations are called Pickering emulsions. They can align with basic sustainability principles. …
