Update from the Field: Pumps in Place, Piping Assembled

September 24, 2014

The Newberry site has been busy with AltaRock staff and contractors assembling stimulation infrastructure over the last few weeks. We’re happy to report that the pumps are in place, generators have been wired in and piping has been welded up. All the equipment has been pressure tested and is up and running as planned.

Assembling the piping and valves for stimulation is no small task. The heavy-duty piping delivers high-pressure water to the wellbore during stimulation.

DTS cable spoolLast night, we started to cool the with low-flow cold water injection. After the wellbore is sufficiently cooled, we’ll install a distributed temperature sensing (DTS) fiber optic cable in the well. The cable provides real-time temperature data along the wellbore and is used in stimulation zone analysis.

Once the DTS cable is installed, a step-rate injectivity test will be performed. The step-rate test will establish a baseline permeability, to compare to the permeability enhancement due to multi-zone stimulation. After the baseline permeability is determined,  stimulation will begin.

Other ongoing site activities over the last few weeks have included groundwater monitoring, and geophysical survey projects overseen by Oregon State University.

Our ongoing groundwater sampling program continues to add to and improve the scientific data available for the area. As part of the sampling program, groundwater was recently collected from seven sites at and around the Newberry EGS Demonstration injection well. Fore more information about the groundwater monitoring program at the Newberry EGS Demonstration, see our previous post on the topic- Groundwater Monitoring and Water Sampling Update.

    how can I save this information for future reference?

    Suddenly Volcano’s erupting all over the world. How can you be sure you are not responsible? Cause and effect. Where are your facts showing what you are doing is not causing these other volcano’s to erupt? For every action there is a reaction. You are drilling into the ring of fire.

    I would refer you to Karl Popper’s musings on the nature and scope of knowledge. He stresses that the problem of distinguishing truly scientific endeavours from the unscientific is based upon those endeavours as being falsifiable. That is, that which is unfalsifiable is also unscientific, and that postulating an unfalsifiable theory (such as that injecting cold water at low pressures in Oregon could even remotely possibly cause a volcano to erupt in Japan) could be scientifically true is pseudoscience (http://www.the-rathouse.com/2008/Bartley1964CCR.html). Another example is the Russell’s teapot analogy (Russell, 1952; available at http://russell.mcmaster.ca/cpbr11p69.pdf), which demonstrates that the burden of proof for a scientifically unfalsifiable claims lies upon a person making that claim rather than shifting the burden of proof to others.
