Controlling Pressure Transmission to Reduce Drilling NPT

Engineered materials and fluid systems for seepage loss control, fracture sealing, and wellbore stability across evolving drilling conditions.

From early seepage to total losses — one continuous response framework.

Engineered Materials for Mud Loss Control and Wellbore Stability in Drilling Operations

Lost circulation, wellbore instability, and stuck pipe events are among the leading causes of drilling Non-Productive Time (NPT). Industry estimates suggest that 25–30% of drilling NPT is associated with these challenges.

InvaSeal Solutions develops engineered materials designed to mitigate seepage losses, control severe mud losses, and enhance wellbore stability in challenging drilling environments.

The Challenge: Lost Circulation and Wellbore Stability

Both Permeability Losses and Fracture (Aperture) Losses are commonly encountered in drilling operations. These conditions can result in:

  • continuous drilling fluid losses
  • well control risks
  • wellbore instability
  • increased rig time and operational costs

Effective mitigation requires reliable loss control materials designed to address a wide range of loss mechanisms.

Applications

InvaSeal materials are applied across a range of drilling conditions where fluid losses and wellbore instability are critical operational challenges.

Seepage Loss Control

Materials designed to restrict seepage losses typically in the range of 25–40 bbl/hr, addressing pore throats and micro-fractures up to 200 µm.

Partial, Severe and Total Loss Control

Engineered solutions capable of addressing high-rate mud losses exceeding 40 bbl/hr, including fractures up to 5000 µm.

Wellbore Stability Enhancement

Materials designed to mitigate Micro-Fracture Propagation and Pressure Transmission, helping maintain mechanical stability during drilling operations.
