Lots of cu­rios­ity at Husky En­ergy’s Foster­ton ASP Flood Open House in Ha­zlet

Ap­prox­i­mately 70 peo­ple from the Ha­zlet area joined more than 20 Husky En­ergy em­ploy­ees at the Ha­zlet Com­mu­nity Cen­tre on March 16 to dis­cuss the com­pany’s pro­posal for an ASP Flood at the Foster­ton Field.

Over the next 25 years, Husky En­ergy pro­poses to ex­tract an es­ti­mated 45 mil­lion bar­rels (about 50 per cent) of the re­main­ing 90 mil­lion bar­rels re­main­ing in the Foster­ton Field which orig­i­nally con­tained ap­prox­i­mately 160 mil­lion bar­rels. That’s some­thing the cur­rent wa­ter flood process can­not ac­com­plish due to the dif­fer­ing vis­cosi­ties of oil and wa­ter, with wa­ter seek­ing the path of least re­sis­tance and the oil re­sist­ing move­ment due to a drop in pres­sure caused by the ini­tial ex­trac­tion that be­gan when the well was first drilled in the early 1950s. Fifty per cent is the best cur­ren­tAl­ka­line Sur­fac­tant Poly­mer flood pro­cesstech­nol­ogy can prom­ise, leav­ing an­other 45 mil­lion bar­rels in the field for fu­ture de­vel­op­ers of En­hanced Oil Re­cov­ery pro­cesses.

En­gi­neer­ing spe­cial­ists with Husky En­ergy ex­plained that wa­ter flood is the most efficient way of get­ting oil out of the ground in terms of cost of en­ergy, but pro­duc­tion us­ing that process has plateaued in the Foster­ton pool.

“Cur­rently we’re pro­duc­ing 99.1 per cent wa­ter and only 0.9 per cent oil,” said Tyler El­lis-Tod­ding­ton, En­gi­neer­ing Spe­cial­ist. Ev­ery day we pull out 100,000 bar­rels of wa­ter and less than one per cent of that is oil that we can skim. That’s a lot of en­ergy to re­move and push that wa­ter back.”

Orig­i­nally con­ceived 30 years ago but never de­vel­oped due to slug­gish oil prices, the ASP flood process is now eco­nom­i­cally vi­able.

“The ASP process was de­vel­oped in the 1980s, and at that time it never re­ally pro­gressed be­cause the oil prices were un­der $20 a bar­rel, so it wasn’t un­til early 2005 when a lot of com­pa­nies started look­ing at it again,” said El­lis-Tod­ding­ton. “With a lot of these tech­niques, af­ter an oil flood, you need a higher oil price to jus­tify the cost.”

What the pro­posal means to Husky En­ergy is in­creased pro­duc­tiv­ity through a greatly ex­tended life­span for the Foster­ton Field. What it means for the re­gion is pos­si­ble long-term growth and em­ploy­ment, and - even­tu­ally - more dol­lars in the pock­ets of well own­ers who are un­der con­tract with Husky.

The ASP Flood will re­quire the con­struc­tion of ad­di­tional sur­face fa­cil­i­ties, to be built ad­ja­cent to the ex­ist­ing Foster­ton site, sim­i­lar to the Gull Lake fa­cil­ity, fol­lowed by the lengthy twostage in­jec­tion process.

Husky En­ergy builds their fa­cil­i­ties with con­tain­ment and sec­ondary con­tain­ment, so if they had a leak on site, it would be con­tained within their fa­cil­ity.

If the Foster­ton ASP Flood is ap­proved, Husky En­ergy ex­pects to be­gin con­struc­tion by May of 2011.
