With a pencil, place a mark at the right-most point of the dividers. You have just marked the first
ten collars on the well. Move the dividers to the right, now lining up the left-most point of the dividers
with the pencil mark you just made. Again, put a pencil mark at the right-most point of the dividers
(below left). This marks another 10-collar section of well casing.
Continue marking 10-collar sections on the tape. When collars are not present all the way to the
bottom of the well, then the divider setting for the last readable collars should be used to estimate the
remaining unreadable collars to the fluid level.
When you can no longer mark 10-collar sections, count the individual points on the dividers to
the remaining joints to the fluid level (above right) – which is the biggest downward kick on the tape.
To calculate joints to fluid, simply count the marked sections, by tens, and add the last few joints
to the fluid. That is the actual collar count – the joint-to-fluid measurement.
Calculating distance to the fluid in feet or meters
To calculate the distance to the fluid, multiply the number of joints by the length of the
casing joint. (This length will be available on the completion sheet for the well.) This will be the
distance to the fluid.
In the above
example,
there are 65 collars marked on the fluid level tape, and the casing joint
length is 32, multiply 65 x 32, and the depth to the fluid is 2,080 feet.
