Historic well and field information:
What do we know?
• Wells were drilled to 300 to 900’ where 15 ½” or 12 ½’ casing was
set and cemented to protect surface water. Drilled to the top of the
Tansill and 8 5/8” cemented with 500 – 600 sacks of cement. Drilled
to TD and produced Open Hole or with liner.
• By 1930, some wells were making as much as 20,000 BW and 50
BO.
• Earthen, unlined pits were used for storage of oil and water. It was
assumed the water would evaporate. In places, however, the water
table rose >10’.
• 3,500 – 9,500 PPM TDS in 1920’s produced water.
• 99,000 PPM TDS in water “passing through salt section”.
• In 1956, 350,000 BWPD was still being diverted to disposal pits at
about the time when water floods were starting.
• Many irregularities in subsurface maps are due largely to errors in
measurement resulting from crooked holes (Ackers, et.al., 1930,
p.934)

WINK SINK I
Measurement of
the “ring
fractures” around
Wink Sink 1
suggests the sink
and the sag to
the east should
be view as a
couplet. The
feature in the bar
ditch of SH115 is
not part of the
previously
existing sets of
fractures.
Hypotheses on Sink development
• There are many possible causes of a cavity
which eventually results in a collapse:
– Fresh waters from shallow aquifers enter borehole
and cause dissolution in Salado Salt
– Existing Cenozoic collapse in Salado is enlarged by
water(s) and collapses
– Brine water from surface pits enters along fractures in
shallow horizons causing dissolution
– Water moving up from Capitan Reef causes
dissolution
– Water lost through casing into Salado causes
dissolution
Arco 3D East west lines indicate “disrupted” reflectors in the evaporite
section. The top of the Yates (Black line) is at approximately 500ms.
Although the location of the Cenozoic Alluvium “Fill Zone” is know as
an area of poor quality seismic data for deeper horizons, There maybe
shallow data present that would be extremely useful to this study
WINK SINK II
The water supply
wells for the city of
Wink are in close
proximity to Wink
Sink 2 (Gray
area), and Sag
Area (Blue area)
both inside the
fenced area.
Monitor wells,
placed between
the Sink and the
town are strongly
recommended.
Wink Sink 2
Wink Sink 2 looking south
Sag Area to east of Wink Sink 2
6” Gas Pipeline
serving Wink has been
exposed for over 2
years. The depth of the
fracture is >13’.
The trend of the this
crack and the one
through the electric
substation is
independent of Wink
Sink II.
