PACKER TESTING

Single and Straddle Packer Systems for Discrete Zone Testing, Sampling and Injection of In Situ Treatment Fluids

Earth Data Northeast has many years of experience conducting packer tests for a wide variety of applications. We offer 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.


SYSTEM APPLICATIONS

Earth Data Northeast maintains an extensive inventory of packers and state-of-the-art data collection devices. Packer systems can be configured for short-term testing 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 in situ treatment fluids
  • Determine pressure response of individual fractures in adjacent monitoring wells
  • Detect casing leaks

PRE-TESTING SURVEYS

Earth Data Northeast can provide complete suites of geophysical logs and borehole video surveys to characterize the well or borehole prior to packer testing.
