There is great reason for optimism about the future of enhanced oil recovery in tight formations. Although pilot projects have been scarce to date, Bakken laboratory studies suggest significant potential for high oil mobilization rates injecting both CO2 and produced gas. New engineered field tests are needed to develop a more complete understanding of EOR in tight oil plays, and yield the fundamental knowledge to take recovery rates to new levels. by James Sorensen and John Hamling. 62 | Advanced Chemical Solutions Key in IOR Economics by Deepankar "Dee" Biswas 69 | Technology Applications Boost Operator Efficiency by Danny Boyd UNCONVENTIONAL RESOURCE SCIENCE 33 | Technology Redefining Mature Field's Reserves Potential by Joe Sonnier, Scott Scholz and Bruce Moriarty 39 | Coiled Tubing Enables Effective Horizontal Recompletions by Brett Fears 44 | Technology Solves Sanding Problems by John H.
