The Reservoir Rock Section: 

The Reservoir Rock Section is build to determine the petrophysical properties of reservoir rocks and basic data necessary for exploration and petroleum engineering work. There are two types of investigations that can be performed in the reservoir rock section:-

Conventional Core Analysis

 Sample Preparation 

•  Drilling and cutting (plugs or whole sample)
• Samples numbering, cleaning with solvent and drying using oven 

 Full diameter core analysis

•  Porosity and grain density
• Horizontal air permeability Kmax, 90 degrees
• Vertical air permeability

 Plug sample core analysis

•  Porosity and grain density
• Horizontal air permeability
• Vertical air permeability
• Horizontal and vertical air permeability including Klinkenberg corrections
• Fluid saturation by Dean Stark or by Retort method
• Digital probe parameter to measure permeability on full diameter of slabbed core 

Special Core Analysis 

•  Mercury injection capillary pressure (multi points)
• Mercury injection capillary pressure drainage & imbibition
• Mercury injection capillary high pressure (up to 60,000 psi)
• Porous plate cell capillary pressure air-water or oil -water multi point at ambient conditions
• Capillary pressure air-water or oil -water by using centrifuge
• Formation resistivity factor at ambient conditions Formation resistivity factor at overburden pressure
• Resistivity index at ambient conditions
• Liquid permeability measurements at ambient conditions
• Clay swelling and fine movements
• Evaluation of critical velocity
• Relative permeability unsteady state at ambient conditions
• Relative permeability unsteady state at reservoir conditions
• Water flood test at ambient conditions
• Amott Wettability (imbibition and dynamic displacement)
• Porosity and permeability as a function of overburden pressure
• Rock compressibility 

Formation Damage Tests:

Newly introduced laboratory and still under construction, hopefully in near future we will finish setting up this lab. with the assistance of a specialized and experienced company in this area in order to operate and maintain the equipment and get some experience to perform tests and work on projects in the area of formation damage.
