NRG Soluble Balls (for Multistage Hydraulic Fracturing 100 megapascals). Soluble balls are used to activate downhole equipment in most termination systems for multi-stage hydraulic fracturing. The ball learned to withstand pressure of 100 MPa for several hours, and then small particles are processed a few days. Soluble balls are made of magnesium (Mg) based alloy. or suffer (Al), who are quickly exposed to the box when exposure to any electrolytic fluid, brine KCl, fracturing fluid or formation water. since the balls are soluble, then to start production, after well stimulation, no additional funds required drilling operations
NRG Dissolvable Balls
- Ball material: magnesium or aluminum alloy;
- Operating pressure: up to 100 MPa, depends on the operating tension between the ball and seat;
- Dissolution medium: brines, fracturing fluid, formation fluid, acids;
- Maximum operating temperature: up to 150 C;
- Electrolyte concentration and temperature affect the rate of dissolution;
- The required dissolution rate varies by the choice of alloy type;
- When used in acid fracturing (HCl) for delayed start of dissolution It is possible to apply a protective coating.
- The ball dissolves even at minimal electrolyte concentrations (from 1%);
- The decomposition product is a fine powder, which does not have a negative impact on well productivity;
- Advanced quality control: testing a ball sample from each batch;
- Application of a protective coating for use in acid fracturing (HCl).
