Lee, I think you can get as much as 10k bbl a day of oil and water combined depending on the well and pressure. I hope you find this thought cheerful.
I don’t think stimulation need be a one-time thing but I think they get more bang for the buck drilling and fracking a new horizontal well. I believe that Marathon refracked some very early 1 frack stage horizontal wells in ND. Had the wells been at least 10 stage I doubt they would have done so. I think the process is rare in long or extended long lateral wells.
