Assessment of clay materials for suitability in drilling mud formulation from part of Ondo State, South-West Nigeria

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Bentonite used for drilling operations in the oil and gas industry in Nigeria is mainly imported into the country. This project evaluated the efficiency of additives and their function in enhancing the rheological and flow properties of local bentonite ...

Effect of dehydroxylation/amorphization degree of bentonite on the microstructure, thermal stability, and mechanical strength of basalt epoxy composites

open access: yesJournal of Materials Research and Technology, 2023
Calcination of smectite clays such as bentonite is tricky due to their 2:1 aluminosilicate structure. Low calcination temperature has minimal effect on the dehydroxylation, specific surface area (SSA), and crystalline nature of bentonite clays whereas ...

Thermally Activated Bentonite As a Supplementary Cementitious Material – A Review [PDF]

open access: yesEngineering and Technology Journal, 2021
Bentonite is a mixture of clay and non-clay minerals. Montmorillonite clay mineral is a dominant mineral in bentonite. Silica and alumina bond in the crystal structure of montmorillonite. Therefore, they cannot contribute to the pozzolanic reaction. Heat

Thermochemical Treatment of Nigerian Raw Clays for Oil and Gas Drilling Operations

open access: yesChemEngineering, 2023
Sodium-based bentonite is used for drilling operations because of its high swelling capacity. This type of bentonite clay is not sourced locally in many oil- and gas-producing nations.

Enhanced biodiesel production from waste cooking oils catalyzed by sodium hydroxide supported on heterogeneous co-catalyst of bentonite clay

open access: yesResearch in Agricultural Engineering, 2023
Various proportions of bentonite clay performing as co-catalysts were evaluated for the production of biodiesel from waste cooking oil (WCO). The results showed that the use of bentonite as a heterogeneous co-catalyst could significantly increase the ...

Bentonite Clay Modified Concrete

open access: yes, 2022
Replacing cement with pozzolanic materials to some extent in construction is found to be one of the sustainable approaches in the construction industry. Pozzolanic materials of industrial origin like fly ash and Ground Granulated Blast furnace Slag will have to be replaced with natural pozzolanic materials once the world moves towards renewable energy ...
