The Problem

Wells producing water are likely to develop deposits of inorganic scales. Scales can and do coat perforations, casing, production tubulars, valves, pumps, and downhole completion equipment, such as sand screens, safety equipment and gas lift mandrels. If allowed to proceed, this scaling will limit production, eventually requiring abandonment of the well.

This limit in production may also be the result of poor perforation technique (high skin due to the “shock damaged region” caused by conventional perforation techniques), organic deposits in existing perforations (such as paraffin and asphaltene), clogging of sand screens etc..

The Solution

By way of high energy focused shockwaves, using the “qWave Pulser” technology, stimulate the areas affected for effective removal of scale, clogging or other deposits in the wellbore or downhole completion equipment, or improving (widening/extending) existing perforations having previously been created by conventional perforation techniques.

Areas of Application

  1. Cleaning and/or improving (widening/extending) existing perforations having previously been created by conventional perforation techniques.
  2. Cleaning of sand screens having been clogged by particles, scale or organic deposits.
  3. Removal of scale deposits from downhole completion equipment, such as downhole safety valves and gas lift mandrels.
