Errata

In the December 2004 issue, paper 77688, "Deconvolution of Well-Test Data as a Nonlinear Total Least-Squares Problem," by T. von Schroeter, F. Hollaender, and A.C. Gringarten, was published with numerous errors caused in part by incompatibility of software formats. We apologize for the inconvenience caused by these errors. The correct version of the paper can be accessed at http://www.spe.org/web/spej/77688v2.pdf free of charge until October 2005. The corrected version has permanently replaced the originally published version in the eLibrary.
