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.
