I must note that the industry is yet to find a generally accepted term to describe this approach. Encana Corp. (ECA) calls this “developing the cube.” QEP Resources (QEP) uses the term “tank-style development.” Laredo Petroleum (LPI) calls its landing zone optimization system the “Earth Model.” However, all operators have the same objective: to produce more oil with less money – and it appears that full-volume stimulation is a must in this regard.
