A recent article in E&P Magazine discusses one of the newest innovations in SAGD production technology.
Oil sands deposits located far below the surface are most commonly recovered using the SAGD method. With oil sands production forecasted to grow by 800,000 bbl/d by 2020, innovative solutions are becoming increasingly important for the industry to keep up with growing demand.
Electric submersible pump (ESP) systems are often used in the SAGD process, as following steam heating some form of artificial lift is necessary to boost the flow of oil to the surface. However, in order to withstand the extreme temperatures, high gas to oil ratios and abrasives typically used in SAGD production, specifically designed ESP systems are required.
Baker Hughes recently installed the first ESP system rated to 275C, which included a new, more robust motor designed specifically for thermal injection. This new ESP technology will allow operators to increase the temperature of the steam, and therefore the size of the steam chamber, improving production and overall reserve recovery. Additional lift also assists with reducing the steam-oil ratio, a metric that “determines the level of emissions generated, operating costs, surface footprint size, capital efficiency, water intensity and water usage.”
