Abstract
A variable stiffness engineered degradable ball or seal having a degradable phase and a stiffener material. The variable stiffness engineered degradable ball or seal can optionally be in the form of a degradable diverter ball or sealing element which can be made neutrally buoyant.
Claims16
A degradable component having a variable stiffness and/or being deformable;
- said degradable component configured to form a temporary seal in a well formation;
- said degradable component includes a degradable metal and a stiffness component;
- said degradable metal forming a continuous phase in said degradable component;
- said stiffness component forming a discontinuous second phase in said degradable component;
- a stiffness or yield strength of said degradable component changes when said degradable component deforms;
- said degradable metal includes degradable magnesium alloy;
- said stiffness component includes non-degradable material;
- said non-degradable material includes micro balloons;
- said microballoons have a crush strength of 500-10,000 psi;
- said non-degradable metal constitutes20-90 vol. % of said degradable component;
- said degradable metal constitutes 40-80 vol. % of said degradable component.
