I *think* what you want might be the Allowable Depletion Report; there's nothing that shows ending NBV, so you either have to trust Lacerte to carry over LHC and accumulated depletion not in excess of basis (which it actually does do correctly), or you have to write your own Excel formula to limit accumulated depletion to basis.

There's nothing special about cost vs percentage depletion in terms of accumulated depletion not in excess of basis. Just enter one number.

As I said to George, I do my well-by-well schedules in Excel, and enter into Lacerte in whichever clumps produce the desired output. So I might have a Property called OK Gain WI and a property called OK Loss WI, both under the Set called Oklahoma Wells. If you have very many small-dollar wells, the rounding really adds up fast.
