What's the best time interval for well log interpolation?

Common AVO synthetic gather generation methods involve the interpolation of well logs to an evenly distributed time grid for convolution with a bandlimited wavelet. We investigate the artifacts associated with different interpolation intervals. To avoid these artifacts, we propose a method for modeling that involves no log interpolation at all. Although not foolproof, there is a special time interval with which satisfactory results can be obtained. Cases where this interval does not work will be described.
