FRAC BALL AND HYDRAULIC FRACTURING SYSTEM

摘要

There is provided a fluid communication-interference body, such as a frac ball, for deployment downhole within a wellbore for effecting interference to fluid communication between the wellbore and the subterranean formation. The body may include a shall and an inner core. The shell includes shell material which may include metal-comprising material, such as titanium. The core includes core material. The core material may include composite material such as microspheres distributed within a polymer material-comprising matrix.

1. A fluid communication-interference body comprising:
a shell including a shell material having a modulus of elasticity of greater than 15 and a tensile strength of at least at least about 15×106 psi, at SATP conditions, and a tensile strength of at least about 50 ksi, at SATP conditions; and an inner core including an inner core material having a minimum compressive strength of at least about 5 ksi, at SATP conditions.
