Well Testing, Monitoring, Servicing & Controlling

Well testing takes on three forms. Ketek can provide you with options for all three.

Groundwater Sampling

For a variety of reasons, clients often need to sample groundwater. Proper practice is to pump out at least three times the volume of water in the well before taking a sample to ensure an accurate, representative sample and not get any contaminants from stagnation.

Aquifer Testing (Pump Testing)

Wells are installed for a variety of reasons, many of which require that the flow characteristics of the aquifer are understood. Obtaining accurate data is paramount for hydrogeologists to establish these characteristics. Reliability of the equipment is a fundamental requirement and also a key strength of Ketek.

Injection Testing

Wells are sometimes installed to be used for fluid disposal. To test the effectiveness of the well for this purpose, pumping must be done at elevated pressures with appropriate monitoring. It is vital that the field crew have a thorough knowledge of the equipment and the process to conduct the test properly.

Well Monitoring

The consistent and reliable operation of a groundwater well observation network is vital and often a requirement of regulators and facility operators.

These wells are likely installed for the purpose of aquifer depressurization, tailings seepage capture or general environmental monitoring.

Through appropriate monitoring, the Ketek team can extend the life of your well systems and your equipment.

The following can be considered:

  • Proper sizing will ensure that pumps operate at optimum capacity and therefore last longer
  • Qualified pump installation will ensure that the well (specifically the screen) remains competent
  • Pump placement (in relation to the screen) will dictate how it is installed to protect the motor, and
  • Attention to the equipment minimizes failures and, in the event of a failure, decreases the turnaround time for repair.

Well Testing, Monitoring, Servicing & Controlling

Some facilities are many years old and the well network associated with it is just as old. It is significantly less costly to revitalize a well than to abandon and drill a replacement.

This is not an exact process as each well has unique and often unknown issues.

Ketek has built custom tooling and applied innovative techniques to clean wells with a high rate of success.

The most common problems include:

  • Damaged screens, letting solids enter the well
  • Separated casing, causing a narrowing or complete blockage of the well
  • The sump is full of solids (over time this may happen)
  • Equipment trapped in the well, and
  • Items dropped into the well. This is often a complex problem as the item may have damaged the screen as it fell.

Water Well Control and Monitoring

Wells that are central to operations or have a longer required usage cycle are more appropriately integrated into the facilities grid, rather than having continuous human monitoring. Costs of ongoing well operation can be significantly reduced by introducing permanent power and electronic monitoring devices, primarily due to fuel savings and reduced manpower requirements.

Ketek’s combined strengths in technical and engineering capability, manufacturing capacity, and hands-on field knowledge allow us to design, build, install, and maintain a well tailored to your specifications, and an Intelligent Pump Control System to go along with it.

Ketek - Water Well Control

Ketek’s Intelligent Pump Control System is designed to be mobile and easy to maintain, and to achieve the following:

  1. Monitor water parameters including, but not limited to:
    • Head pressure
    • Temperature
    • Electrical conductivity
    • pH
    • Total suspended solids
    • H2S concentration
    • Flow rate, and
    • Total flow
  2. Communicate with existing facility devices for centralized data collection, and
  3. Connect groundwater pumped to a permanent or semi-permanent surface or subsurface flow network.
