Reduced Costs Associated with Steam Generation

Challenge

Steam generation accounts for 65% of the operating costs for oil sands operators who employ thermal in-situ recovery techniques. Because of this, steam oil ratio (SOR) is one of the key performance metrics for measuring the performance of these operations. Consequently, operators are constantly looking for innovative ways to reduce the amount of steam required to effectively mobilize the viscous bitumen and to get it flowing to the producer well and surface. Any improved thermal efficiencies that can be gained through innovative well construction, completion and operations warrants serious consideration.

Solution

Halliburton’s solution is a highly insulative foam cement. This foam cement increases steam injection efficiency by lowering conductive heat loss surrounding the injector wellbore and features superior insulating properties. These corrosion resistant foam cements are also available for low pH conditions. The result is improved oil flow and lower on-going well operating costs. In addition to this technology, Halliburton has a reliable supply of base cement materials.

Summary Summary VersaSeal™ Cements
Foamed cementing solution designed to be mixed at a wider range of densities than standard foam cements.
Summary Summary ZoneSeal® Isolation Process
A fully engineered zonal isolation process with automated controls to deliver the benefits of light-weight (foam) cement during placement and for the life of the well.
Summary Summary ZoneSealant™ 2000 Agent
A single-component cement foamer/stabilizer that can be used in fresh water, seawater, and salt slurries for use in standard applications requiring foamed cements.
Summary Summary Dual Injection ZoneSeal® Process Job—Western U.S.
In this Western U.S. well, the ZoneSeal® dual injection method was chosen because of significant CO2 gas breakthrough in the wellbore annulus (~3,000 ppm), plus the fact that pumping down the annulus was projected to be a way to contain/kill CO2 gas.
