Numerical approximation improves well survey calculation April 9, 2001 It is now possible to improve the precision of well survey calculations by order of magnitude with numerical approximation.

When this approximation is valid, we say that we're in the linear regime, and these calculations can be done by human hands, without the need for a numerical simulation.

A numerical error is either of two kinds of error in a calculation. The first (a rounding error) is caused by the finite precision of computations involving floating ...

Abstract: We propose a nonlocal gradient structure approximating the aggregation equation motivated by the classical upwind scheme widely used for the numerical approximation of first order equations.
