WelSAVER™
Advanced Multi-Modal Bridging Technology for Drilling Fluid Loss Control
WelSAVER™ is an advanced multi-modal bridging technology engineered for drilling fluid loss control. Formulated with a wide, engineered particle size distribution, WelSAVER™ delivers effective mechanical sealing across a broad range of fracture widths, vugs, and highly permeable formations encountered during drilling operations. The multi-particle system promotes rapid seal development, supports sustained circulation, and enhances wellbore stability under variable loss conditions. By reducing fluid invasion and maintaining system integrity, WelSAVER™ helps improve drilling efficiency and minimize non-productive time.
Advantage
- WelSAVER™ is engineered with a broad particle size distribution to bridge and seal fractures, vugs, and permeable zones of varying apertures.
- The engineered blend promotes rapid lost circulation control without significantly increasing equivalent circulating density when used as directed.
- Compatible with water-based, oil-based, and synthetic drilling fluid systems, supporting flexible deployment across different well environments.
- The formulation helps sustain circulating returns and minimize solids influx during loss events.
- WelSAVER™ simplifies logistics by serving as a single broad-spectrum additive rather than requiring multiple particles or blend sequences.
Application
- WelSAVER™ is used to mitigate partial to severe lost circulation during drilling operations.
- It is effective in naturally fractured formations, high-permeability sands, vugular intervals, and depleted zones.
- The additive may be introduced into the active drilling fluid system for continuous seepage control.
- For more significant loss events, WelSAVER™ can be pumped as part of a dedicated lost circulation pill.
- It supports wellbore strengthening strategies where fracture sealing and stress cage development are desired.
Environmental Advantage
- WelSAVER™ meets LC50 aquatic toxicity testing criteria, supporting environmentally responsible drilling operations.
- Efficient loss mitigation reduces drilling fluid waste and minimizes the total volume of fluids and additives required on location.
- Improved fluid retention lowers the likelihood of repeated treatment cycles, decreasing overall material consumption and associated rig time.
- More stable hole conditions reduce unnecessary trip cycles and associated operational impacts.
- Enhanced drilling efficiency contributes to lower fuel usage and a reduced overall environmental footprint.
