Summary: This study presents a series of studies on the production of organobentonite and its use as a matrix grain-binding material in casting moulding sand. Shungite, a new carbon additive, was introduced into the moulding sand composition. Technological and strength properties of the green sand bond with organobentonite and shungite as a new lustrous carbon carrier were determined. The positive effect of shungite on the quality and quantity of gaseous products generated from the moulding sand and its reduced environmental impact were confirmed.

Summary: The French gravel industry produces around 6.5 million tons of gravel wash mud annually, which has promising properties for construction material use after in-depth characterization study. By adding fly ash and seashells, the material shows high compressive strengths and potential for reducing wall thickness. The use of these new materials, with reduced porosity and improved strength, aligns with Sustainable Development Goals and contributes to lowering carbon emissions.

Summary: A temperature- and salt-resistant polymer filtrate reducer, PAAAND, was synthesized and found to effectively maintain the stability of drilling mud under high-temperature and high-salt conditions by increasing the zeta potential of clay particles and particle size distribution width. The PAAAND filtrate reducer also reduced filtration loss by making the filter cake formed by clay particles smoother and denser.

Summary: Drilling fluid rheology and fluid loss properties are crucial for drilling operations, especially under high temperatures. This study synthesized and characterized modified corn starch as an environmentally friendly rheology enhancer and filtration loss controlling agent for water-based mud. Experimental results showed that MCS outperformed traditional additives in improving rheological properties and controlling fluid loss, with biodegradability properties.

Summary: This study reviews the application of different types of organoclays in oil-based drilling fluids (OBDFs), investigating their structures, rheological properties, and thermal stability. The study also illustrates the role of fibrous and layered organoclays in enhancing the rheological properties of OBDFs, as well as the synergistic use of different organoclays to improve thermal stability. The research highlights gaps in knowledge and provides recommendations for further investigation in this field. The application of organoclays in OBDFs has significant potential for development and contributes to progress in the oil and gas industry.

Summary: The objective of this work is to study the effect of adding anionic polymers on the rheological characteristics of a water-based drilling mud. The results show that the addition of poly-salt in a concentration range of 0-1 wt% increases the yield stress, viscosity at zero and infinite shear rates, and may also increase the thixotropic behavior of the drilling mud. Furthermore, analyzing the time-dependent effect of different concentrations of poly-salt added to the drilling mud at 20 degrees C using a structural kinetic model reveals valuable insights.

Summary: With the increasing demand for energy, there is a growing need for drilling activities and the use of drilling mud in the oil and gas industries. However, the high cost and importation of drilling mud materials, such as bentonite, have become a burden on companies and the economy. This study aims to explore the potential of using locally sourced clay, specifically Ikwo clay from Ebonyi State, as an alternative to commercial bentonite. The importance of this research lies in its potential to reduce costs and dependence on imported materials. Rating: 6/10.
