Integrated approach for sustainable management of drilling residues using stabilisation and solidification techniques
Présentation :
Drilling operations, a critical phase in oil and gas extraction, generate substantial amounts of drilling fluids and cuttings containing hazardous materials, including heavy metals and hydrocarbons. If not managed properly, these by-products can cause severe environmental damage, such as soil contamination, water pollution, and disruption of ecosystem. As global efforts emphasize the importance of sustainability and environmental conservation, finding effective solutions for managing drilling waste becomes crucial. This study focuses on the treatment and recycling of drilling muds generated from the Zarzaitine oil fields, located in the Illizi basin,30 kilometers east of In Amenas. The adopted methodology relies on stabilisation and solidification (S/S) techniques, which are widely used to reduce the volume and toxicity of hazardous waste. These processes convert harmful drilling sludges into more stable and less toxic materials, minimizing the risks associated with its disposal implementing such solutions aligns with sustainable waste management principles in the oil gas industry. By recycling drilling fluids and reducing hazardous waste, companies can meet stricter environmental regulations while lowering the environmental impact of their operations. Furthermore, the recycled products can sometimes be repurposed, promoting a circular economy approach. The findings of this research highlights the effectiveness of stabilisation and solidification methods in mitigating environmental hazards. It demonstrates that proper waste treatment not only protects natural ressources but also encourages a shift towards more

Enhancing Djebel Onk black phosphate processing parameters for phosphoric acid production
Présentation :
The objective of this study is to evaluate the potential behaviour of black phosphate in the production of acid phosphoric. A qualitative comparison of the two phosphates(black and beige) from Kef-Essnoun de Djebel Onk was carried out during the first part of this study, with the aim of defining the differences between the two types of phosphate. Phosphate is the most widely exploited mineral currently, and is completely devoid of organic matter. In the second part, the studies focused on black phosphate samples ground to two particles sizes, 100 and 80 microns, in order to define the effect of grinding on the quality of the chemical composition of the ore to be etched. Etching parameters, such as phosphate flow rate, were adjusted. The effect of overflowing the tank was also considered.
Keywords: Phosphoric Acid, Black phosphate, Immersion time, Etching Attack, Organic Matter, Dihydrate Process.
