Frequently asked questions

What is core orientation?

Core orientation is the process of determining the original position of a drill core sample. When combined with downhole survey results, it gives the core sample location and orientation before it was extracted from the ground. Geologists use this data to measure structural features, such as bedding planes, fractures and veins, aiding in the creation of a geological model and identification of subsurface formations.


There are two broad categories of core orientation methodology: manual and digital. These methods help determine the precise orientation of rock formations within a drill core sample.


Some core orientation methodologies include (and can be seen as complementary):
•    Electronic Core Orientation Instruments 
•    Dipmeter and borehole televiewers 
•    Structural Geology techniques (field observations, mapping, geophysical methods, and laboratory experiments)
•    Photogrammetry

What holes sizes is the ACTIII compatible with?

The ACTIII can be used to orient core in hole sizes N, N2, N3, H, H3, P, LTK60, B, BTK®, W/L56, W/L66, W/L76, BTW, NTW
