Paper Number: SPE-203961-MS
... "truncation error" grid measure which is probably the most accurate measure for flow through a plane face and accurately measures the error along the strata. We also quantified the error due to the face curvature. Curved faces are bound to exist in any real grid. The impact of the quality of the 2-D Delaunay...

... into account the truncation error made during the time step and thus are not optimal. Jensen, recognizing the deficiency in these algorithms, has suggested an algorithm based on Gear's method used in the solution of linear differential equations. In Jensen's method the truncation errors are estimated using...

Paper Number: SPE-7690-MS
... Abstract Individual well modeling with r-z geometry is often done with a small number of radial cells (e.g. 6 or 7). This usually leads to small space truncation error for black oil systems. for power law fluids a finer grid is required. An example problem is readily solved using 20 radial...
