Drilling Basics: Geology and Groundwater
Full course description
This course focuses on the basics of Geology and Groundwater.
The Geology Basics section is a fundamental overview of the different types of rocks and subsurface
structures a driller may encounter. The first subsection addresses rock formation, as well as big-picture
geological processes that shape subsurface structures. By emphasizing sedimentary characteristics and
soils, the curriculum centers around porous media to which groundwater typically resides. The section
finishes out by covering the different components of subsurface structures, emphasizing key
terminology and phrases often shared among the drilling profession.
The Groundwater Basics section introduces the movement of groundwater and barriers to flow. The hydrogeology introduction explains the pathways from precipitation to groundwater and how water moves through natural cycles and porous media. The groundwater flow subsection describes the many characteristics of aquifers and how groundwater flow is calculated. This is followed by full explanations of the different types of pumping tests. This section ends by discussing the different issues associated with well flow by describing potential drinking water contaminants and aspects of well clogging.
