Schlumberger has introduced the ELEMENTAL degradable alloy balls for multistage stimulation treatments. The technology demonstrates predictable, complete degradation of the alloy balls, ensuring maximum well productivity.
The alloy balls degrade predictably in a wide range of downhole conditions, well depths, temperatures, pressures and well fluids. Controlled degradation takes place, without the need for chemical additives, low pH environment, retrieval operations or milling after fracturing.
The ELEMENTAL degradable alloy technology can be used with Schlumberger multistage stimulation systems. The technology has been deployed with the Falcon multistage stimulation system for uncemented wells in formations representing a significant challenge to degradation times, such as Gold Creek, Slave Point, Glauconite, Cardium, Montney and Lower Montney, with bottomhole temperatures as low as 86°F. The technology has also been used in the Bakken, where formation temperatures are around 260°F.
