A bit late to this but lets revisit the disaster that is QEP. Going back several years they’ve tried their damnedest to get more oily. Since 2015 they’ve made $1.6B in property acquisitions. (After a $1B Permian buy in 2014). From 2015 thru 2018 they’ve spent ~$4.1B in CAPEX.
In 2014 oil production was 47mbopd. Q2 2019 oil production was 57mbopd. A 10mbopd increase after $5.7B in spending. 5.7 billion dollars.
