There are three files:

1) 56A_1_PressureData_20160404 (Kuster memory tool)

2) 81B_1_PressureData_20160404 (MadgeTech pressure and temperature recorder)

3) SP_2_PressureData_20160404 (MadgeTech pressure and temperature recorder)

These files contain data collected from:

1) A MadgeTech PRTemp1000IS pressure and temperature recorder.  These pressure recorders, at surface, are reading pressure from 1/8” stainless steel capillary tubing run to a depth below the water table and filled with nitrogen.  The data is subject to temperature fluctuations and nitrogen density, both of which can be accounted for.

2) A Kuster memory tool was deployed to a depth below the water table.  The tool remained in the well for the duration of the test then was recovered to download the recorded data.  This tool provides a more accurate pressure since the recorder is downhole.

The data was collected during three distinct pumping schemes:

1) March 13th 2016 through March 18th 2016. Plant shutdown. All wells (injection and production) are shut off until water levels are, more or less, constant over time.

2) March 18th 2016 through March 23rd 2016. What is referred to as “flooding the field” by Ormat. This is a period during which three infield and one outfield injection wells were injected with water and five production wells were pumped from until water levels, more or less, constant over time. 

3) March 20th 2016 through March 22nd 2016. +/- 10% periodic changes in flow rate. During this period, which is actually superimposed onto the period 2), flow rates are changed periodically by +/- 10% of the flow rate at all injection wells.
