Well Video Surveys
The standard deliverables for a welenco video survey are as follows: On site, one or two VHS tapes (please let us know in advance if you need more than one) and a hand written survey report. Within 5-7 days we provide any additional VHS copies you request (up to three at no charge), a color printed Video Survey Report with still image captures, and a 3.5" floppy or CD (your preference) with all still image captures in .jpg format. Also we are now able to transfer surveys to CD ROM or DVD. This is a great idea if you want to archive your well videos. We can usually fit a 1000' survey on a CD and much more on DVD. This service is provided for an extra charge but it is minimal since we do all the work in-house. Click on the link above for more information about this service. Welenco operates several types of down-hole video cameras, each is best suited to certain conditions, click on the links above to find specifications on each type to assist in picking the camera that would work best in your scenario. Call us today to schedule a well video and get your well back to peak performance. (800) 961- WELL (9355) |

Video
surveys are run for a variety of purposes in both existing
and new wells. In new wells a video log is often run to
confirm the "as-built" construction of the well,
to inspect for damage such as corrosion, casing breaks,
holes, splits, and other deformities. Surveys are also
performed to determine the source of sand or gravel entry
or falling production rates. Video surveys are usually
conducted prior to and after cleaning or repair operations
to assess the effectiveness of the maintenance. Occasionally
videos are used to aid in "fishing" operations
for equipment that has fallen into the well. In open (hard-rock)
boreholes a video survey can be used to locate fracture
zones which may produce water. 
During
a video survey the down-hole camera is lowered into the
well and the image is observed on a video monitor and
simultaneously recorded on up to three VHS cassettes.
The depth that the camera is currently at is superimposed
onto the video image and is also recorded. During the
survey the operator may capture still images of areas
of interest like those shown on this page for later viewing
on a PC and printing on the Video Report form. Welenco
maintains a permanent archive copy of the Video Report
form, however due to storage space limitations it is our
policy to archive the recorded survey for 30 days except
under special circumstances.
