Abstract
The present invention provides methods and systems for numerically computing tool response sensitivities of subterranean measurement tools such as resistivity logging tools. The methods and systems enable much faster computation of sensitivities than previously available for resistivity tools. For typical tools that apply dozens or hundreds of parameters, the methods of the present invention may reduce sensitivities computation time by a factor substantially equal to the number of parameters.
