4. Procedure



  1. Test = Test 1 + Test 2 + Test 3

  2. Test 1 = high freq pulsations (10 pulses with 0.3 day)

  3. Test 2 = mid freq pulsations (10 pulses with 1.5 day)

  4. Test 3 = Low freq pulsations  (5 pulses with 5.5 day)


5. Intepretation


  1. Numerical model

    1. Single well with circle boundary

    2. High density LGR

    3. High density time grid (seconds)

  2. Automated pressure match in PolyGon software
