DESCRIPTION:Polly Keen\, BP Institute\, University of Cambridge \nTitle: E
 ncapsulation of microorganisms in colloidosomes\nAbstract: Polymeric micro
 capsules called colloidosomes have been prepared encapsulating undamaged v
 iable Baker’s yeast cells\, E.coli and Lactobacillus.  The method of pre
 paration\, the encapsulated cell properties and the diffusion limitation o
 f species such as glucose through the colloidosome shell have been investi
 gated.\nWei Jin Gun\, BP Institute\, University of Cambridge \nTitle: Enca
 psulation of Inhibitors for Down-well Applications\nAbstract: During oil r
 ecovery\, a water flood forces oil from porous rocks. However\, oil-rich l
 ow permeability regions are a major problem. This research investigates th
 e possibility of using microcapsules to lower the permeability of\, or eve
 n better block-off\, high permeability regions. Microcapsules\, containing
  thickening agents\, are flowed through porous media with distinctive perm
 eability regions. Measurements determine how the capsules affect the total
  permeability and flow fronts of both high and low permeability regions. R
 esults show a decrease in total permeability when microcapsules are introd
 uced and release of thickening agents\, produced a similar effect. This al
 lows control over the flow path taken.\n
