Liquid thixotropic agent
Helps manage lost circulation during cementing from offshore platforms or any other location where the handling of solid additives is impractical.
PressureNET fiber- and solids-based lost circulation solution combines dispersible CemNET technology fibers with vitrified shale particles to stop lost circulation in shale, dolomite, or carbonate formations. The various-sized shale particles build up throughout the 3D CemNET fiber network, creating a base for cement slurry solids to pack off the loss zone.
The strength of the shale helps the lost circulation material withstand high differential pressures across the fracture, reducing the volume of drilling fluid and cement lost to fissures and natural fractures.
PressureNET lost circulation solution can be added to water-, oil- and synthetic-based cement slurries, spacers, and drilling fluids in batch mixers or mud pits.
Maintain stability over a broad bottomhole temperature range.
Mitigate the risk of lost circulation while drilling with a specially engineered pill.
Increase the effective solid volume fraction of carrier fluids such as muds, spacers, and cements.
Advances in fiber-based technology in lost circulation control treatments.
The continual increase in exploration drilling in southern Africa has translated into a number of remote deepwater campaigns, the most recent ones being in Namibia. One particular three-well campaign was exceptionally challenging as there was no near offset-well data available.
