Project Final Report-08123-16-The goals of this project were to evaluate deepening and behind-pipe opportunities and enhanced oil recovery (EOR) potentials to maximize recovery from the East Texas Oil Field (ETOF), a giant mature and marginal field currently operated by 114 small producers. This field demonstration project has two industrial partners, Danmark Energy LLP and John Linder Operating Co., and two primary goals: (1) locating well-deepening and waterflooding targets guided by depositional trends through detailed mapping of reservoir architecture, and (2) conducting a feasibility study on EOR methods for recovering a portion of the ~1.1 billion stock tank barrels (BSTB) of residual oil.
