Summary of BRK, page-414

For better transparency, here you go TTC. Heres my estimates of Jewel production by month. Estimates are based on gridlines from the production curves from the quarterly announcements and I have estimated NGL (i have assumed consistent Gas vs NGL). Actuals are from published numbers, some of my intra-quarter periods might be out, but they all come out in the wash once the green actual production is known.

Note steep initial decline (as you mentioned) and the decline is continuing (as expected) but at much slower rate. The key however is the high initial rates allow the BRK to quickly recoup drilling and completion costs and recycle those funds into additional wells.
