“…Large volumes of water are injected into aging oil wells in order to recover the maximum amount of oil, and this leads to the production of huge amounts of oil-water mixture (or "produced water"). 1,2 As this produced water is considered environmentally hazardous, oil producers are now legally bound to recycle the produced water. 3,4 Every year, millions of barrels of crude oil and refined petroleum products are spilled into the seas by tankers, offshore platforms, drilling rigs and oil cargo ships, 5 causing extensive damage to marine ecosystems.…”

Surfaces which possess extraordinary water attraction or repellency depend on surface energy, surface chemistry and nano-and microscale surface roughness. Synergistic superhydrophilic-underwater superoleophobic surfaces were fabricated by a spray deposition of nanostructured TiO 2 on stainless steel mesh substrates. The coated meshes were then used to study gravity driven oil-water separation, where only the water from the oil-water mixture is allowed to permeate through the mesh. Oil-water separation efficiencies of up to 99 % could be achieved through the coated mesh of pore sizes 50 and 100 micron, compared to no separation at all, that was observed in the case of uncoated meshes of the same material and pore sizes. An adsorbed water on the TiO 2 coated surface, formation of a water-film between 2 the wires that form the mesh and the underwater superoleophobicity of the structured surface are the key factors that contribute to the enhanced efficiency observed in oil-water separation.The nature of the oil-water separation process using this coated mesh (in which the mesh allows water to pass through the porous structure but resists wetting by the oil phase) minimizes the fouling of mesh so that the need for frequent replacement of the separating medium is reduced. This fabrication approach presented here can be applied for coating large surface areas and to develop a large-scale oil water separation facility for oil-field applications and petroleum industries.

Abstr actThe scale and magnitude of pressure perturbation and brine migration induced by geologic carbon sequestration is discussed assuming a full-scale deployment scenario in which enough CO 2 is captured and stored to make relevant contributions to global climate change mitigation. In this scenario, the volumetric rates and cumulative volumes of CO 2 injection would be comparable to or higher than those related to existing deepsubsurface injection and extraction activities, such as oil production. Large-scale pressure buildup in response to the injection may limit the dynamic storage capacity of suitable formations, because over-pressurization may fracture the caprock, may drive CO 2 /brine leakage through localized pathways, and may cause induced seismicity. On the other hand, laterally extensive sedimentary basins may be less affected by such limitations because (1) local pressure effects are moderated by pressure propagation and brine displacement into regions far away from the CO 2 storage domain, and (2) diffuse and/or localized brine migration into overlying and underlying formations allows for pressure bleed-off in the vertical direction. A quick analytical estimate of the extent of pressure buildup induced by industrial-scale CO 2 projects is presented. Also discussed are pressure perturbation and attenuation effects simulated for two representative sedimentary basins in the U.S.: the laterally extensive Illinois Basin and the partially compartmentalized southern San Joaquin Basin, California. These studies show that the limiting effect of pressure buildup on dynamic storage capacity is not as significant as suggested by EhligEconomides and Economides 1 , who considered closed systems without any attenuation effects.

“…(Oil-bearing rocks also contain original water in their pores which is produced with the oil; oil reservoirs produce more and more water as the oil is pumped out, to be replaced in the pores by inflowing water.) Daily oil production of over 80 million barrels is accompanied by well over 200 million barrels of water (Veil, Puder, Elcock and Redwell, 2004). Reversing that total flow of some 300 million barrels a day, by injecting into existing reservoirs (say) 2,500 million tonnes of carbon a year, in the form of over 9,000 million tonnes of carbon dioxide, would cope with 125 gigatonnes of carbon (450 gigatonnes of carbon dioxide), about 70% of the 2004 Princeton target for controlling emissions through to the middle of the twenty-first century.…”
