Daily Shift Report

Date: 2/28/2018

Written by (SURF Personnel): Hunter Knox

 

Location(s):  4850 Level - EGS Collab SIGMA-V (Collab)

 

Summary of Work:

Assembly of the downhole monitoring packages for PDT and set-up of the monitoring equipment.

Purpose: Installation of the monitoring gear for EGS Collab SIGMA-V

 

Science Hours (total) on Site:

Surface: 7.5  hrs

Underground: 57  hrs

 

Irregularities:

       The planned evacuation caused a delay in both shipment of personnel and equipment to the 4850. However, the shaft crew did an amazing job delivering gear to SIGMA-V for our efforts.

 

Actions:

       Continued testing of the bend radius for the fiber measurements in the 4850.

       Shipment of 3 loads down the Yates to SIGMA-V for monitoring equipment.

       Continued assembly for the monitoring package in PDT.

 

Observations:

       PSB was flowing at 2.5 mL/min today. It was the only well that was observed to be flowing.

       The saw horses are a huge ergonomic improvement to our work for installation.

       We assembled the monitoring package for PDT today. We had to move it down the drift to get the bottom section of the package into the wellbore. When this was done, we were unable to move it without some damage to the conveyance pipe. We broke two joints in the pipe. We caged up at an earlier time so that we could retrieve supplies for the hardware store that will help with movement of the package tomorrow. We anticipate that the improved procedure will be adequate for installation into both the PDT and PDB wells tomorrow.

 

Documents or Procedures: JHA-006 Geophysical Monitoring System Assembly and Installation.

Materials Receiving/Shipping:

       Shipments were made from the Yates Headframe to the 4850 with help from Richard Goetz and George Vandine.

       Equipment for the stimulation was made to the Yates Headframe. George Vandine and Richard Goetz worked to get the sensitive equipment into the Saw Mill.

       We will continue to work on getting other equipment into an appropriate (i.e. climate controlled) space tomorrow.

       The additional PVC pipe was delivered today to the Ross Warehouse. This pipe needs to be sent to the Yates Headframe (or other location as determined by George Vandine) so that it can be cut to fit on the cage.

 

Daily Safety Briefing:

       Use team lifting when required for offloading equipment.

       Be careful of hand injuries and pinch points during the assembly of the gutter.

       Lots of equipment is present in our work zone, watch for slip/trip/fall hazards and tidy up.

       Monitoring installation inherently has repetitive motion, so frequent breaks should be taken. Stretching is also greatly encouraged.

       Take your time and get it right. This a complex installation, which requires significant concentration and focus.
