1. A method for defining logging while drilling measurements to be used for proactive well placement while drilling a high angle or horizontal wellbore in a reservoir, the method comprising: providing an initial reservoir model for the reservoir; extracting a section of the reservoir model for a planned trajectory of the wellbore; generating, using a computer, a secondary model by performing secondary modeling for at least part of the planned trajectory; identifying, using the computer, an area of interest within the secondary model where statistical uncertainty is high; defining possible causes of the statistical uncertainty in the area of interest within the secondary model that are not present in the initial reservoir model; defining a set of parameters for the area of interest based on the possible causes of statistical uncertainty; modeling, using the computer, logging tool responses in the area of interest for at least one logging while drilling tool; evaluating, using the computer, sensitivities of the modeled logging tool responses to a subset of the set of parameters by generating and assessing at least one tertiary model for a range of the subset of parameters; identifying, using the computer, which parameters correlate to greatest sensitivities in the modeled logging tool responses from the subset of parameters and corresponding logging while drilling measurements; and defining, using the computer, one or more logging while drilling measurements to be used for proactive well placement along the planned trajectory based on the parameters that correlate to the greatest sensitivities in the modeled logging tool responses.
