Circulation loss is a complication, which occurs during the well drilling process. The problem of сirculation loss can also be encountered when carrying out a squeeze cementing. Fractures and caverns in formation cause catastrophic absorption of drilling fluids and cement slurries. Effective circulation loss control allows eliminating these problems, significantly save time and financial resources.

LOST CIRCULATION ROOT CAUSES

  • Fracturing reservoir properties: the presence of pores and fractures, permeability (the ability of the rock to pass liquids and gases), saturation (the content of oil, gas in the sedimentary interstices).
  • Tectonic disturbances (various kinds of displacement, fractures, caverns).
  • FORMATION PRESSURE.
  • Drilling mud properties and other factors.

CIRCULATION LOSS CONTROL IS CARRIED OUT BY THE FOLLOWING BASIC METHODS:

  • filler materials placement;
  • cement slurries injection;
  • casing;
  • freezing;
  • explosion of the loss zone and others

With the use of these technologies,experts of the Mirrico Group have carried out dozens of operations to circulation loss control with an efficiency of 90% and higher.

Having received from the Customer a completed questionnaire with problems at the well, our experts will select the most effective circulation loss technology. Using this service will significantly reduce technological downtime.
