SANJEL ENERGY REDUCES BAKKEN PRODUCTION CEMENTING COSTS BY 30 PERCENT

Challenges

The Bakken formation is very distant from other prolific plays in the Western Canadian Sedimentary Basin and this remoteness has at times led to delays in the trial and adoption of many of the newer technologies and efficiencies adopted by producers in plays closer to the technology hubs.

The Bakken’s distance from other major oilfield centers changes the economic model and makes well costs a challenge. Remote locations in SE Saskatchewan and Western Manitoba require operational solutions that address low-temperature wells and clay-rich formations. These solutions must meet the minimum well requirements while managing costs and inefficiencies.

Solutions

Bakken wells require slurry combinations that provide zonal isolation in the producing zone that will see direct fracturing stresses and a competent lead cement that gains cement returns to surface and resists any immediate gas flow into the column during the setting process.

Lead cements in Sanjel Energy’s LITEmix family can be successfully combined with PRODUCTIONmix tail cements to create an effective cement sheath. This synergistic pairing meets all the well needs, economically and technically, delivering more profitable wells.

Additional capabilities include:

• Sanjel Energy’s reactive preflushes and clay controls stabilize formations and improve cement bonds.
• Intelligent use of pozzolan chemistry improves performance while reducing cementing costs.

Results

• Reduced production cementing costs by 30 percent in specific areas
• Improved bond logs and reduced vent flows in the SE Saskatchewan area
• Optimized lead and tail mixes reduced the number of blends required and simplified bulk storage and operations
