The Wink Sinks
We are pleased
to announce that the Study of the Wink Sinks has begun. Through
the support of industry, The Bureau of Economic Geology (BEG)
and University of Texas of the Permian Basin (UTPB) have
received funds that are sufficient to begin Phase One of the
study which includes:
v
A
better understanding of the extent and rates of ground
subsidence and identify areas of potential risk to public safety
and infrastructure in Winkler County.
v
Build data bases for the Wink to Kermit area to serve as a
spatial framework for all the study results. These will include
topography, transportation and public service infrastructure,
aerial photographs and oil and gas wells and petroleum
infrastructure.
v
Complete an Interferometric Synthetic Aperture Radar (InSAR)
analysis at the Center for Space Research at UT Austin.
Satellite data is being acquired to identify priority areas
showing anomalous rates of recent vertical movement of the
ground surface that can be indicators of potential sinkhole
development.
v
Digital Photogrammetry of older sets of aerial photos that can
be used to determine high-resolution topographic changes that
preceded the development of Wink Sinks 1 & 2 and the associated
Sags. This is necessary to determine if subsidence preceded Sink
Hole development.
v
Collection of oil and gas well data to determine if changes in
the status of well bores and near well bore changes during the
past 80 years can be identified and related to the development
of the sinks and sags. We will be asking operators to provide
data for this portion of the study.
v
Maintaining contact with the local stakeholders and partners is
critical and we hope that a frequent exchange of pertinent
information can speed and sharpen the focus of the project. To
this end, a monthly newsletter will be sent to Sponsors and
Stakeholders and informational meetings will be held.
This represents
the First of Three Phases of the program. In the future, when
funding becomes available, the US Geological Survey will
investigate the potential effect of the Sinks, and their root
causes, on the potable ground water in the Wink-Kermit area.
UTPB will investigate the circulation of deep, saline ground
waters, interpret the shallow structure in available 3D seismic
surveys and expand the study of the well bore and near well bore
intervals on trend to the north and south. The BEG will generate
high quality Light Detection and
Ranging (LIDAR) which is a remote sensing system used to
collect topographic data, and conduct surface mapping of
the sink areas.
Among the
Sponsors are Chevron and Apache Corporation. Devon has made a
$50,000 gift to the University of Texas, Jackson School of
Geosciences earmarked for the Wink Sink Project. Other oil
companies have also made donations.
