Lost Circulation



Click to view
This figure illustrates the various Schlumberger solutions that can help regain well control when lost circulation occurs.


  • CemNET
    Controls lost circulation to improve cement returns.

  • InstanSeal
    Novel lost circulation treatment.

Cure lost circulation and reduce drilling costs
Avoid stuck pipe, mud losses and remedial work with our effective, customized solutions.

First, we identify the type and cause of the lost circulation problem.

Type of loss zone
  • Loss into a naturally fractured rock requires a different treatment than loss into porous or vuggy formations.
Pressure differentials
  • A complex balance exists among the pore pressure in multiple layers, fracturing pressure and hydrostatic head of the well fluid.
Temperature limits
  • Treatment techniques can be limited by wellbore temperatures and application times.
Duration of plugging
  • Permanent or temporary solutions fit into the life cycle of your well.
Formation damage
  • Uncontrolled loss propagates damage deep into the reservoir. The skin created by effective plugging materials can be bypassed through perforating or a small stimulation treatment.
Our experience, products and services are the optimal solutions for these situations.
