Routine Core Analysis

Core Handling
GEOTECH has over 20 years experience in handling cores of various sizes and lengths. Core samples are usually shipped directly from the drilling rig to our laboratory facility, normally in 1m lengths but occasionally in 9m long aluminum barrels. GEOTECH's core laboratory is equipped with heavy duty lifting gear to safely manage cores of any length. GEOTECH's core shed has the capacity to view and store large amounts of cores.



Surface Core Gamma
The core gamma surface logger is designed to measure and record natural gamma radiation in core sections. The core gamma log is most commonly used for correlation purposes and to distinguish different lithological units.


Core Slabbing (Fully Automated Slab Saw)
Cores are slabbed to provide a flat surface for core description / photography / profile permeametry. GEOTECH operates state of the art continuous "hands free" core slabbing equipment which is not only safer and quicker than normal slab saws, but also provides a more evenly slabbed surface devoid of any "circular blade" marks. This improved slabbed surface enhances the appearances of the core in the core photographs and facilitates profile permeametry measurements. GEOTECH is capable of slabbing core sections encased in aluminum by using a specially developed blade, which can simultaneously cut through rocks and aluminum in a single pass.


Core Plugging (Consolidated and Unconsolidated Core)
A cylindrical plug is taken from a conventional core for analysis. Core plugs are typically 1" to 1½" (2.5 to 3.8 cm) in diameter and 1" to 2" (5 cm) in length. Core plugs are ordinarily cut perpendicular to the axis of the core (horizontal plug) or parallel to the axis (vertical plug). Geotech also cuts plugs in other than standard diameters and trimmed to any length.
