Special Core Analysis
Special Core Analysis Services include the following analyses at room & reservoir conditions:
- Electrical Properties measurements, Formation Resistivity Factor and Resistivity Index by different methods.
- Capillary Pressure measurement by Porous Plate and Centrifuge and by Mercury Injection.
- Wettability measurements, Harvey Amott, USBM & Combined.
- Relative Permeability by Unsteady & Steady state methods.
- Core Flooding analyses.
- Rock Mechanics Acoustic properties and more.
Special Core Analysis Project Design
- The planning of SCAL studies is often left until the conventional core analysis is complete.
- Quality of any SCAL study will depend upon the initial sample conditions.
- The objectives of any SCAL study should be defined prior to coring to ensure that the optimum coring, core handling and core preservation techniques are used.
Electrical Properties
In order to Determine Archi’s equation Constants Datalog applies several core 
electrical properties measurement techniques:
- FRF at both room and overburden conditions to get the “m” constant.
- Resistivity Index by both in conjunction with capillary pressure and by continuous injection method to get the “n” constant.
- “a” constant is then empirically calculated by FRF curves.
- Clay Corrections “BQV” are also measured by either CEC or COCW methods.

Relative Permeability
As Flow assurance is one of the key parameters needed by production engineers, determining relative permeability curves are necessary, Datalog is supporting various
operators in the determination of relative permeability by both:
