Shale Rock Properties (SRP)

Contact

Shale rock properties (SRP) analysis determines fundamental core data sets for reservoir characterization. SRP is crushed analysis that yields porosity, permeability, saturation, bulk, and grain density data.

Why crush? Pore connectivity and pathways in shales affect the ability to accurately determine petrophysical properties on core sample. Induced fractures from coring and sample handling also affect permeability determinations. Mitigating these factors is done by crushing the sample. 


SRP analysis begins with intact sample material. The sample is then crushed and processed to obtain fundamental rock properties.

The analytical method begins with an initial bulk measurement on intact, as-received material. The sample is then quickly crushed to yield less than 1/8-in. sized material (all sample material is used). An initial grain density and permeability measurement is then determined. Pore fluid saturation data is determined by Dean Stark Toluene extraction, followed by further cleaning with chloroform/methanol to remove any residual hydrocarbons suppressing porosity. A final grain density and permeability measurement is determined, and data is reported in tabular format.


SRP analysis offers you the ability to obtain valuable data where conventional testing methods are limited.
