DEFINITION 1
in the ground
TERM 2
Why would one drill?
DEFINITION 2

install a well for extracting petroleum and water
TERM 3
contour map
DEFINITION 3
A contour line (also isoline or isarithm) of a function of two
variables is a curve along which the f unction has a constant value.
contour maps are maps that -map illustrated with contour lines,
for example a topographic map, whic h thus shows valleys and
hills, and the steepness of slopes.[3] T he contour interval of a
contour map is the difference in elev ation between successive
contour lines.[4]
TERM 4
cross sections
DEFINITION 4
profiles for example: by knowing the surface elevation of
each drill site and the depth at which it was found the
elevation and thickness of the sandstone can be determined.
From this data one can make a contour map showing the top
of the sandstone and cross-sections showing its relationship
to other units above and below
TERM 5
Aquifer
DEFINITION 5
An aquifer is a wet underground layer of water-bearing
permeable rock or unconsolidated materials (gravel, sand,
silt, or clay) from which groundwater can be usefully
extracted using a water well. -is a layer of rock or sediment
that has high hydraulic conductivity
