One of the main objectives of well no. 7 is to establish productivity of J1
J1 has a high permeability gravel layer in all wells
Production logging (PLT) should be run to evaluate the effect of this gravel layer

NOTE: This can have an impact on how future producers are drilled and completed

PLT is important for location of future producers.
Must producers be completed in gravel layer?
Should producers be vertical and fractured?
Is high rate dependant skin, D, in well 4 (and 7?) due to the high perm layer?
