Land subsidence is a threat that occurs worldwide as a result of the withdrawal of fluid and also underground mining. The subsidence is mainly due to excessive groundwater withdrawal from certain types of rocks, such as fine-grained sediments. Mitigating the effects of land subsidence generally requires careful observations of the temporal change i...

Experimental study on the use of locally produced ester-base fluids at the drilling of shale formation
Article
Full-text available
For the successful drilling of oil and gas drilling, the drilling fluids are essential materials. In drilling applications, the most commonly used drilling fluids are water-based fluids. Water-based fluids are the first fluids of choice for drilling applications because of their cost-effective, environmentally friendly and non-hazardous nature. How...
Experiment Findings
Full-text available
Drilling fluids play an important role in the successful drilling applications of oil and gas wells. This role of drilling fluid in oil exploration and exploitation activities is similar to the blood circulation in the human body according to some researches. The most commonly used drilling fluids are water-based fluids in the drilling applications...

Drilling fluids play an important role in the successful drilling of oil and gas wells. Water-based mud is the first mud of choice for drilling operations because of its cost-effective, environmentally friendly and non-hazardous nature. This material is the most commonly used mud in these operations. However, wellbore instability encountered while...

Artisanal mining is an activity associated with several environmental impacts, which are deforestation and land degradation, open pits which pose animal traps and health hazards, and mercury pollution, dust and noise pollution. In this study, the environmental influences of artisanal gold mining in Sudan have investigated. Approximately about seven...
Conference Paper
Full-text available
Underground exploitation of mineral resources is often carried out in a watered rock mass. Dewatering of rock layers disturbs its geomechanical equilibrium, consequently resulting in deformations occurrence on the terrain surface. Furthermore, modeling of rock strata dewatering and related land subsidence is still a complex issue, mostly due to una...
