It has been widely acknowledged that core handling is critical to the maintenance of core integrity. Unfortunately, cores often don’t undergo adequate handling procedures

The rig site handling of unconsolidated core is a risky process that might hamper core integrity if appropriate procedures are utilized.

The main purpose of core preservation is to retain the pore fluids in the undisturbed core samples thus preventing saturation and wettability alteration.

Cases of invasion of core-stabilization products into fractures are often seen. This represents a common and often serious problem in the subsequent geological description of slabbed cores.

The fundamental objective of coring is to obtain core that is representative of the reservoir rock properties.

StoreCore primarily serves the Oil Industry but also provides services to numerous Universities and Research Institutions.

Kirk Petrophysics provides expert on-site core handling services.

Core plugging

Core Plugging- Tunisia Kirk Petrophysics supplies and operates an air powered plugging tool that is capable of extracting 1” diameter plugs from sleeved cores. The tool is mobile, compact and is capable of cutting through the aluminium, GRP, or steel sleeve before sampling the actual core.

The following special core analysis can be carried out on 1” x 1” plugs at core laboratories:

Capillary pressure, porous plate, centrifuge, mercury injection
Electrical resistivity a, m, n
Liquid permeability
Formation damage
Rock mechanics.

The well site core plugging tool is an air powered device, mounted on a drill stand to provide extra stability. A foot operated clamp holds the plugging tool securely over the inner barrel (it can be altered by moving the jaws of the clamp into the next predrilled position, facilitating different tube diameters).

A single air supply provides power for the motor and also provides cooling and cleaning for the cutting blade. A combined filter/regulator unit helps to control the supply pressure and removes water and abrasive particles. The air lubricator unit deposits an oil mist into the air supply to lubricate the motor and prevent corrosion of any downline equipment.
