How do you conduct a slug test?

How do you conduct a slug test?

A slug test involves the instantaneous injection or withdrawal of a volume or slug of water or solid cylinder of known volume. This is accomplished by displacing a known volume of water from a well and measuring the artificial fluctuation of the groundwater level.

What is a pneumatic slug test?

Pneumatic slug tests use pressurized air or nitrogen as the slugging agent. The well is sealed, and the water column is pressurized. As the pressure increases, the water level drops and water is forced out of the column and into the aquifer.

What is packer testing?

Packer testing is a technique in which one or more inflatable bladders, or packers, are used to isolate different regions of a borehole for hydraulic testing or water sampling. This webinar will introduce appropriate approaches, methods, and equipment for borehole packer testing applied to hydrogeologic projects.

What is an Overdamped slug test?

Overdamped slug tests typically occur in aquifers of low to moderate hydraulic conductivity (K) and exhibit the type of response depicted in Figure 2. Figure 2. Data from a typical overdamped falling-head slug test in an unconfined aquifer with fully submerged well screen (data from Batu 1998).

When would you use a slug test?

A slug test is a controlled field experiment performed by groundwater hydrologists to estimate the hydraulic properties of aquifers and aquitards in which the water level in a control well is caused to change suddenly (rise or fall) and the subsequent water-level response (displacement or change from static) is …

How is pump test conducted for evaluation of aquifer parameters?

A pumping test is a field experiment in which a well is pumped at a controlled rate and water-level response (drawdown) is measured in one or more surrounding observation wells and optionally in the pumped well (control well) itself; response data from pumping tests are used to estimate the hydraulic properties of …

What is double packer test?

Double Packer’ Hydraulic Conductivity Testing The, ‘double packer’ system is undertaken with 3 inflated packers, whereby one packer is inflated within the 146mm Geobore S casing, one underneath the casing shoe and another at the bottom of the clients requested test section.

How do you test a packer build?

Build AMI with Packer. Launch instance based on AMI. Run Serverspec tests against instance….My preferred pipeline would look like:

  1. Build AMI with Packer.
  2. As the final build step, run Serverspec.
  3. If the tests fail, abort the build.
