Lost Circulation Cementing Solutions

Solutions that mitigate a wide range of lost circulation challenges

Lost circulation is commonly encountered in drilling and cementing operations and can be a costly challenge to overcome. During cementing, lost circulation can compromise zonal isolation and, ultimately, impede production. Risks associated with lost circulation affect most wells, particularly those with naturally fractured formations, unconsolidated zones, and vugular flow paths. Induced losses can also occur when the hydrostatic fluid column pressure exceeds the fracture gradient of the formation and the formation breaks down enough to receive rather than resist the fluid.

Our solutions can mitigate the wide range of lost circulation challenges encountered during cementing operations, which include:

• Proactive prevention of seepage to moderate losses with our Tuned® Defense™ Cement Spacer Systems
• Addition of bridging or plugging materials, such as our proprietary BridgeMaker™ Lost Circulation Material portfolio, to cement spacer designs for severe losses
• Use of rapid-set or thixotropic cements, like our SentinelCem™ Cement System, for severe to total lost circulation environments
• Reduction of slurry density with tailored lightweight cement designs
