       Before promising locations at petroliferous basins become
       productive oil wells, it is often necessary to complete
       drilling activities at these locations.  The scheduling of such
       activities must satisfy several conflicting constraints and
       attain a number of goals.  Moreover, resource displacements
       between wells are also important.  We describe a Greedy
       Randomized Adaptive Search Procedure (GRASP) for the scheduling
       of oil well development activities with resource displacement.
       The results are compared with schedules produced by a well
       accepted constraint programming implementation.  Computational
       experience on real instances indicates that the GRASP
       implementation is competitive, outperforming the constraint
       programming implementation.
