Featured this monthThe Tantalizing Promise of Oil ShaleAs much as 6 trillion bbl of in-place resources of oil shale are estimated to exist worldwide. With world proved reserves of crude oil estimated at 1.3 trillion bbl, why does oil shale remain a scarcely touched resource?
Guest Editorial Baker Hughes’ new CEO Martin Craighead writes about how the oilfield service industry of the future must be built on the bedrock of effective risk management.
Reducing the Hidden Costs of Subsea Well Completions Subsea completions tied back to platforms have allowed marginal fields to be put into production, but maintaining that production long enough to reach the industry average for recoveries is an unsolved problem. A small group of companies are working to change that.
Unconventionals, Future Challenges Highlight Annual Conference Coverage of the 2011 SPE Annual Technical Conference and Exhibition in Denver, which featured presentations on shale and other unconventional reservoirs, long-term global energy strategy, environmental considerations, remote operations, and other important regional and discipline-focused topics.
Management Real-time data is not about well control, it is about well control avoidance. Recent catastrophic blowouts have underscored the value of real-time data and have also underscored the value of having the right kind of experience to understand well data interpretation in real time.
EOR Performance and Modeling
Baojun Bai, SPE, Associate Professor of Petroleum Engineering, Missouri University of Science and TechnologyIn spite of continued investment and advances in exploiting alternative-energy sources, oil and natural gas will continue to be a significant portion of US and global energy portfolios for decades. Enhanced oil recovery (EOR) uses unconventional hydrocarbon-recovery methods that target the approximately two-thirds of the oil volume remaining in reservoirs after conventional-recovery methods have been exhausted.
Storing CO2 With Next-Generation CO2-EOR Technology Carbon dioxide enhanced oil recovery (CO2-EOR) has potential for storing significant volumes of CO2 emissions while increasing domestic oil production. The causes of suboptimal CO2 storage and oil-recovery efficiencies by current CO2-EOR practices were examined to determine how a group of advanced or "next-generation" CO2-EOR technologies could increase CO2-storage volumes and oil recovery. Introduction A […]
Rheology of a New Sulfonic Associative Polymer in Porous Media For hydrophobic associative polymers (APs), incorporating a small fraction of hydrophobic monomer into a partially hydrolyzed polyacrylamide (HPAM) polymer can promote intermolecular associations and, thereby, enhance viscosities and resistance factors. The behavior of a new AP in porous media was investigated. Introduction In polymer or chemical floods that use polymer for mobility control, the cost […]
EOR Potential in the Middle East: Current and Future Trends The number of enhanced-oil-recovery (EOR) projects in the Middle East (ME) has increased over the past decade. This is a review of current ME EOR projects, from full-field developments to field trials. The option of advanced-secondary-recovery, or improved-oil-recovery (IOR), technologies before full-field deployment of EOR can be a better first option before deployment of capital-intensive […]
