2015-10-5 · Do not drill at excessive rates. Signs of disturbance are excessive slough in the SPT barrel, drill fluid in the sample, and failure of the sampler to rest at the proper cleanout depth. Slough is the disturbed material in the drill hole that caves from the sidewalls but can include disturbed sand that heaves or flows upward into the drill hole ...

THE BASICS OF LOGGING CORE FOR EXPLORATION

Knowing where your hole starts is important, but just as important are the direction its going (azimuth), what angle its being drilled at (dip) and its projected length (EOH). All drill records will have an azimuth, dip and length recorded – these are values needed to actually drill the hole. The azimuth is just a direction to turn the rig.

Drilling and Logging Techniques in Exploration Geology

• Percussion sample yields a crushed sample, comprising cuttings from a fairly well-determined depth in the hole • Beyond that, the drill hole itself can provide a complementary amount of information, particularly by logging using devices to detect physical anomalies, similar to the geophysical surveys mentioned above.

Drilling - Geological Survey of Ireland

Drilling. Drilling is the process of penetrating through the ground and extracting rocks from various depths beneath the surface for confirming the geology beneath and/or providing samples for chemical analysis. The tip of the drill is known as a drill-bit, which is attached to the longitudinal drill-rod and penetrates the ground to form ...

RAB Drilling - Bostech Australia

RAB. This is an older exploration drilling method no longer commonly used. Sample quality is less accurate than Air Core due to the use of a single tube. This means that samples have the risk of contamination through contact with the geology of the drill hole. This is because the sample recovery is outside the drill-string. Air Core drilling is ...
