Rumored Buzz on Well Testing - Wells - Private Water Systems - Drinking Water

Nine single-well pump tests were completed amongst the 5 CSWs and four of the MWs to examine permeability, sustainable pumping rates, hydraulic connection, and standard groundwater conditions. Notably, testing showed great hydraulic connection in between the CSWs in the ore zone horizon and no significant reactions in any of the MWs in overlying or underlying horizons (see Figure 2).

A full-blown well pattern injection and pumping test was carried out to determine hydraulic connectivity for the Test Pattern as a whole, and to assess possible production rates for the pattern. The test was run as a customized 4-spot pattern as there was an unexpected failure of the submersible pump in GWR-042.

Pumped groundwater from each of the external wells (GWR-038, GWR-039, and GWR-041) was recycled for injection in the center well (GWR-040) to produce a closed system. Production rates for the Test Pattern attained a sustainable rate of 45. 3 litres per minute ("L/min") injection in GWR-040 with very little pressure on surface stabilized with 15.

The 2-Minute Rule for Lt

This test fundamentally attained the 50 L/min flow rate assumed in the PFS for an operating well pattern. Hydraulic control of the Test Pattern was validated by no significant hydrologic actions observed in any of the overlying or hidden monitoring wells. Following the full-scale injection and pumping test, an ion tracer test was finished using the 4 functional CSWs in the Test Pattern.

3 L/min injection at the center well and a well balanced extraction circulation of 15. 1 L/min at each of the 3 outer wells. The ion tracer, including a 15% concentration of potassium chloride (KCl) by weight, was injected as a preliminary slug into the Test Pattern at GWR-040, followed by a chase stage involving the recirculation of water drawn out from the 3 outer wells (closed system).

Breakthrough of the ion tracer, as observed by a boost in the TDS, happened at the 3 extraction wells within 9 hours (GWR-039), 12 hours (GWR-041), and 14 hours (GWR-038). Full Article observed throughout the field test follow previous hydrogeological modelling performed by Petrotek (see news release dated June 4, 2020).
