In water well drilling rig operations,
clay and loam—soft soils—bring unique challenges.
Clay is highly plastic;
its stickiness rises sharply when wet.
Loam mixes sticky soil with sand grains. It has loose structure but strong water retention. These soils cause two main issues during drilling:
-
Clay particles cling tightly to bits, forming thick mud layers. This drastically reduces the bit’s cutting ability.
-
After the bit passes, loam hole walls shrink without support. This “diameter reduction” increases drilling resistance.
These problems lower efficiency and may even cause hole accidents. Understanding soft soil traits helps choose the right drilling plan for water well drilling rig.
