It is now possible to improve the precision of well survey calculations by order of magnitude with numerical approximation. Although the most precise method of simulating and calculating a wellbore ...

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 ...

Britain's highest mountain has 'grown' by a metre in the last 65 years, experts have discovered. A new Ordnance Survey (OS) calculation found Ben Nevis stands at 1,345m (4,412ft) rather than the ...
