SUMMARY:Origin of H2S in surface casing vent flows: a case for near-wellbor
 e heating and preferential migration
DESCRIPTION:Go to the 20th floor and check in with reception. You will then
  be directed to the meeting room.\n\n\nOrigin of H2S in surface casing ven
 t flows: a case for near-wellbore heating and preferential migration. \nH2
 S has more recently been detected in surface case vents of SAGD injector a
 nd production wells. This raises the concern that H2S generated during aqu
 athermolysis during SAGD operations is leaking to surface.  Sulfur species
  chemical and isotopic compositions can be used to establish the origin of
  the H2S gas. Here we present a case study showing that the surface casing
  vent flow (SCVF) H2S is coming from near surface aquifers due to near wel
 lbore heating of immature organic matter and deteriorating surface casing 
 cement seals. Methods to assess the origin of H2S using water\, gas\, oil\
 , and organic matter are discussed including other applications to H2S ori
 gins in unconventional reservoirs. \n\n\nBio:\nDr. Jennifer Adams received
  a B.Sc. (Honors Geology\, 1998) from the University of Waterloo\, a M.Sc.
  (Hydrogeology) from the University of Alberta (2001)\, and a Ph.D. in Pet
 roleum Geochemistry from the University of Calgary (2008). Jennifer worked
  on projects focusing on water chemistry\, deep basin CO2 & H2S sequestrat
 ion and basin fluid property prediction.  Jennifer co-founded an oil and g
 as geochemical service company\, Gushor\, in Calgary in 2006 which provide
 d oil source and alteration studies\, accurate heavy oil and bitumen fluid
  property measurement\, production allocation and surface leakage forensic
  work. In 2009 she joined ConocoPhillips and supported domestic and intern
 ational exploration and production activities as a geochemist and basin mo
 deler in onshore North American unconventional plays\, heavy oil deposits 
 and international gas plays. Jennifer has taught several internal courses 
 on heavy oil and bitumen\, biodegradation\, unconventional resource fluid 
 evaluation\, and basin modeling.
