  • Compressive strength of rocks - PetroWiki

    Jun 04, 2015· Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but …

  • Heavy oils—seismic properties

    mary seismic signature of, say, a steam flood, may be the result of crossing the bubble point and not the thermal or even steam phase effects (see for example, Jenkins et al., 1997). Hence, the resulting signature will be a complex combination of fluid, rock, and recovery process characteristics. Let us first examine the response of crossing

  • Pore fluid effects on rock mechanics - PetroWiki

A co-axial rotating smeared crack approach was used to model the nonlinear behavior of the mass concrete in a 3D space which is able to model cracking/crushing under static and dynamic conditions.

  • Grinding Mill - Eastman Rock Crusher

    Crushers are used to reduce particle size enough so that the material can be processed into finer particles like powders in a grinder. So, a typical processing line at a mine might consist of a crusher followed by a SAG mill or a ball mill. In this context, grinding mills like ball mills are considered grinders rather than crushers.
