STRADDLE PACKER TESTING

print this topic
 

Earth Data Incorporated has extensive experience conducting packer tests for a wide variety of applications. Earth Data offers complete, self-contained packer systems operated by highly trained and experienced field personnel. Our professional staff will work with you to plan a packer testing program to meet your specific needs in a cost effective manner.

Earth Data Incorporated maintains an extensive inventory of packers and digital data collection devices. Packer systems can be configured for short-term testing, semi-permanent, or permanent installations. Packer systems can be used to characterize discrete intervals within a well or borehole to:

§         Determine the vertical extent of groundwater contamination

§         Determine vertical head distribution and flow potential in an open borehole

§         Conduct pumping/injection/slug tests in isolated fractures or screened intervals

§         Determine fracture permeability

§         Collect water samples from discrete fractures or screened intervals

§         Seal-off zones of poor water quality

§         Inject tracers

§         Determine pressure response of individual fractures in adjacent monitoring wells

§         Detect casing leaks

PRE-TESTING SURVEYS
Earth Data Incorporated can provide complete suites of geophysical logs and color TV surveys to characterize the well or borehole prior to packer testing.
