Wellbore curvature and torsion greatly influence the forces applied on the downhole pipe string and its consequent deformation. They serve as the bases for calculating the drag and torque of a pipe ...

Over the past several decades, various methods have been proposed to evaluate drilling costs and complexity, but because of the large number of factors and events that affect drilling performance, ...

Acoustic Logging While Drilling (ALWD) techniques utilise sound waves to characterise subsurface geological formations in real time during drilling operations. This method involves the transmission ...

A borehole is a narrow shaft drilled into the ground, either vertically or horizontally. It is constructed for different purposes, such as the extraction of water, petroleum, and gases, etc. Drilling ...

Arsenic is so common in groundwater in Bangladesh, Nepal, western India, Myanmar, Cambodia and Vietnam all heavily populated countries in the flood plains draining the Himalayas that their drinking ...

Johannesburg residents and businesses, weary of persistent water cuts and infrastructure woes, have increasingly turned to boreholes as a solution. But before you drill, it’s crucial to understand the ...

Environmental Geologist Fidelis Adigwe has called on the Nigerian government to quickly implement and enforce tougher rules on borehole drilling to protect the groundwater reserve. With over eight ...
