When we arrived at B207 we sounded the hole with a open bottom dump baler. The Hole depth was 690' 8" We then souned the hole with a closed bottom DB. Hole depth was at 690' 6". This indicates 2" of mud on top Calculate is will take 1.023 cuft of set grout to bring the hole up to 685. Mix grout and trip in. With loaded baler hole bottom is at 691'. Good trip a delivery of grout. After hole prep we loaded US55 and 10 sacks of grout into the install trailer. US55 was put on test at 1750. 1830 we left site. There is a 150w lamp and 250w heat lamp on in the trailer to try to keep the grout and strainmeter "warm" Tomorrow's plan is to install US55 at 685 feet. _______________________________________________ strain-int mailing list strain-int@pbo.unavco.org http://pbo.unavco.org/mailman/listinfo/strain-int From: Wade Johnson Date: October 17, 2007 10:28:06 PM MDT To: yellowstone@pbo.unavco.org, Strain Cc: Subject: [yellowstone] B207 Install update 10/17/07 Today we installed US55 at 687 feet from casing level (685 from ground level.) Install went smoothly. We did have some issues with the compass test box which delayed the install till late afternoon. More details to follow tomorrow. Thanks to Taka'aki, Mick, Nick, Steve and Tyson for all of your help and hard work today! Especially with the cold weather and snow! -Wade _______________________________________________ strain-int mailing list strain-int@pbo.unavco.org http://pbo.unavco.org/mailman/listinfo/strain-int From: Wade Johnson Date: October 20, 2007 11:40:54 PM MDT To: yellowstone@pbo.unavco.org, Strain Cc: Subject: [yellowstone] B207 install report 10/20/07 10/18-19/07 48 hour waiting period...

Test Seismometer #108. 1100 lower seismometer on coated steel cable 1148 seismometer installed 5 feet off bottom 1155 install 1 1/4" pipe for heat measurements. Appears that we have a leaky joint and pipe is filling with water. 1320 600ft of 1 1/4 installed 1329 Shut down GTSM logger to adjust temp settings 1340 Trip in 1 1/2" pipe 1545 Pipe at bottom of hole. 668.4 feet. This puts the seismometer at 663.4 feet. Pull pipe back 4 feet. ~1600 begin cementing hole 1717 finished pumping 35 94lb bags of cement down hole (1.5 cu yards) this should lift the hole about 200 feet Trip pipe back into casing. Flush pipe with water. Clean up grouter 1815 Try to pull data off GTSM. Can't get USB memory stick to work. 1837 Off site Future plans.

You will therefore need to make alternate arrangements to have one on site (eg from Tim or one of your other spares Are you aware that we supplied another one on your PO 2472 in June). I do not have a field suitable one in house but will get one made up this week and ship it to you at The Yellowstone Park as soon as it is done ( assuming you are still there). In respect of the problem you had with the USB, it sounds like the USB connector has been knocked off perhaps when you did the temperature re-adjustment? I say this because I took a USB data dump off the unit on the evening of the deployment and all was fine then. Just open the logger board and check the cable which runs from the USB port on the front panel to the PC104 board (it will be the PC104 end of that cable). Alternately you can pull the data off via the RJ45 connector.
