Daily Shift Report

Date: 2/27/2018

Written by (SURF Personnel): Hunter Knox

 

Location(s):  Motor Repair Shop, Yates Headframe, 4850 Level - EGS Collab SIGMA-V (Collab)

 

Summary of Work:

Shipment of the monitoring gear to the EGS Collab SIGMA-V site, Guide Walks, and assembly of the monitoring gear for PDT.

 

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

 

Science Hours (total) on Site:

Surface: 16.5  hrs

Underground: 38  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:

       Testing of the bend radius for the fiber measurements at the Yates Headframe.

       Shipment of 5 loads down the Yates to SIGMA-V for monitoring and grouting equipment.

       Guide walks for Chris Strickland and Timothy Johnson

       Began assembly for the monitoring package in PDT.

 

Observations:

       None of the wells were flowing.

       The water level in PST was observed to be nominally 30’ below the collar. This will be tested more precisely tomorrow.

       The saw horses will be a huge ergonomic improvement to our work for installation. We will work with SURF to have them shipped to the SIGMA-V site 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.

 

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.

Figure 2: Improvement on the lighting situation for the area between the stimulation/production wells and the parallel shallow wells. This is important for safe and accurate installation of the ~200’ monitoring strings.

Figure 3: EGS Collab team works together to layout out the predetermined design for PDT. Each person was assigned to marking out the locations for a single phenomenology (i.e. ERT, CASSM, etc.), which helped people ensure the complex design parameters will be met. Measurements were double checked after mark out.
