surface generation with spaced 2D lines

Tue Jun 11, 2013 5:29 pm

Hi,
I'm a PhD student and I would like to ask if someone knows how can I create a surface from a 2D low density seismic grid that only extends a given distance away from each line. This is to avoid over extrapolation of the interpretation.
I know I can create polygons around the lines and use them as boundaries, but I have several different surveys in a wide area, with an intricate design and that would be very time consuming...
I know in geoframe this is possible, can I do it in Petrel as well?
Thanks in advance!
