Well Spacing and Royalties

This is probably a really dumb question but it is drving me nuts so I have to ask.

I have royalties that were running a pretty consistant number, let's call it $100 with standard 640 acre spacaing in the section. Then the operator ask for and was granted revised spacing of 320 acres and immediately spudded a new well. The month after the change in well spacing was granted the royalties decreased by 50% to $50 and have remained there. is this coincidence or does 50% of the existing production get escrowed until the DO on the new well is issued?

What is the section township and range ?

30-T12N-R22W

Found nothing about them changing the spacing. The completion test showed a great well but long term production is not for some reason .

Apache has a permit for the Taylor 30-12-22 horizontal well. Approved October 7, 2013. To the Hoxbar. On the west side of the section 30, increased well denisty requested approved september 2013. Royalties cut 50% from OCtober to November. Probably just a coincident.
