Presentation Transcript

  1. Water Well Test Pumping Aztec Engineering Co., Ltd.

  2. Aquifer tests are designed to determine: The amount of storage available in an aquifer The rate at which water can flow through an aquifer The Radius of Influence i.e. the distance from a well to the limit of the cone of depression Aquifer Tests

  3. Aztec Test Pumping • Pumping rates from 1 L/s to 100 L/s • Fully digitized data recording – Flow & Level • Electronic pump speed control. • Pumping units come fully equipped, ready for work. • Truck mounted cranes up to 16 ton lifting capacity. • All weather operation, -50°C to +50°C. • Satellite Communications – voice & internet.

  4. Test Pumping Units Aztec have 3 separate pumping units available. • Unit 1 – flow rate up to 45 L/s, 4” manifold • Unit 2 – flow rate up to 17 L/s, 3” manifold • Unit 3 – flow rate up to 100 L/s, 6” manifold

  5. Fully Digitized Data Recording • Water Level – down hole pressure transducers with on board memory, direct read cables. • Flow Rate – Turbine flow meter with integral reed switch connected to data logger. Ultrasonic flow meter with on board data logging.

  6. Electronic Pump Speed Control • Aztec utilizes ABB manufactured variable speed drives (VSD). • Smooth step test transitions • Constant flow (+/- 1%) for duration of constant rate test. • No flow control valves required in flow manifold, which eliminates flow rate inconsistencies when using valves.

  7. Fully Equipped • Gensets – 2 x 50KVA, 150KVA, 625KVA • Pumps – 3” to 12” diameter. 1 L/s to 100 L/s • Franklin Hi-Temp submersible motors. • Column Pipe – 2” ID to 8” ID. • 5” to 8” column pipe with integral 1” tubes for dipmeters, transducers, etc. • All handling tools • Certified lifting slings for all loads.

  8. Truck Mounted Cranes • Tadano - 5 ton lift capacity • XCMG - 16 ton lift capacity

  9. All Weather Operation • Capable of continuous operations through temperatures of -50°C to +50°C. • Control cabins and generator housings are fully insulated.

  10. Satellite Communications • Aztec uses BGAN satellite communication. • Voice & internet/email, anywhere on the globe. • Daily Reports…..daily! • Test pumping data as requested.

  11. Pumping Test Data Presentation • All depth & flow data are collated in MS Excel and graphically displayed.

  12. Pumping Test Data Presentation • All depth & flow data are in tabular form also for pasting into most aquifer test analysis programs.

  13. Shipping & Transport • All pumping units & equipment are housed in standard 20’ shipping containers. • International & Domestic transportation handled with ease.
