Dependable, Durable, Versatile and Field-Servicable

Once these auxiliary testing devices are in place, predetermined horizons can be continuously monitored. Tigre Tierra® Packers provide independent access to each horizon so that changes within a horizon can be induced from the surface.

Straddle Systems:

Accessing the horizontal and vertical extent of groundwater contamination requires the completion of a network of monitoring wells.  One technique involves drilling several well clusters with each well completed to a specific horizon.

A more cost effective technique is to drill fewer wells and complete each well to multiple horizons within the same borehole.  This technique allows further cost reductions by permitting the use of straddle packer systems that allow sampling from multiple horizons within a single well.

The isolated horizons are predetermined by the distance between the two packers, which can be varied according to site conditions. As with other techniques, several well volumes must be removed to assure that representative samples are obtained. However, a straddle packer system does isolate and reduce well volume, thereby minimising sampling time and expense.
