The Staggering EOG Mandaree Wells -- July 13, 2019

Data points to observe:

• cumulative production: 300K+ in in less than three years; one well at 500K; another approaching 600K
• huge amounts of sand
• the dreaded decline curve, but production still going strong
• correlation between cumulative production and amount of sand
• the "chronological" numbers for these wells (in red bold below)

Reminder: EOG was one of the first to take the lead in acquiring sand/using large amounts of sand. Some of have suggested the company should be renamed EOG &Sand.
