Item Description: This innovative research, into understanding the flow behaviour and effective use of viscoelastic surfactant systems (working assembly-disassembly properties, common worm-like micelles formations) as fracturing fluids in porous-media, tackles the fundamental industrial issue of how to hydraulically stimulate oil-wells (rock-pore formations) to generate enhanced oil-recovery. The science involved addresses the counterpart-problem and underlying deficiencies in bespoke constitutive equations, with emphasis on extensional viscosity response, to qualitatively capture observed pressure-drops in contraction-flows. The work is supported by Schlumberger and CONACYT-Mexico (joint Phds, £100k+ funding, publications), with significant impact upon this worldwide market for such oilfield services (standing at $12.2 billion pa).
