I will use fractures and the bottom of the casing to correct the depth numbers Depth from Camera: 764.8' Bottom of Hole 672' Sand stone layer 671' - 664' Vert Fracture 653 thin layer of darker material. 644 Thin layer of oxidized material 638 Series of healed vertical pull apart fractues 632.8- 632.5 Large open fracture. No sign of flowing water. "fluffy" sediment in fracture. 632- 631.2 Series of healed fractures 631.2 Thin bed of darker material 606.7 Inclusion fell out of wall rock. Left imprint. 596.1 - 591.6 Shale interbed. Ugly 582.5- 582 interbed and Fractures 569.8 " 568 Big fracture 567.3 " 566.8 " 560.1 Layer of banded material. Very cool looking. 543.9 Big fracture 540.4 " 484 Fracture with sediment 492.9 Huge Fracture with sediment on ledge 488 Fracture 479-474 series of fractures 443-441 " 426.6 Duct Tape.... Yes I did say duct tape. 421.1 End of duct tape goes into hole at bottom of large vertical fracture. 392.5 Bottom of casing. Vertical fracture disappears behind casing. top of casing. Camera reads -1' at point where we zeroed it. Overall the camera looks great! We plan on Lifting the Hole 100 feet to 657 tomorrow using trimmy pipe. Monday we will use the dump baler to do our final lift to final install zone. waiting on High resolution temp profile before making fine decision on install zone. _______________________________________________ strain-int mailing list strain-int@pbo.unavco.org http://pbo.unavco.org/mailman/listinfo/strain-int From: Wade Johnson Date: August 20, 2007 11:11:09 PM MDT To: Strain Subject: [strain-int] B900 install report. 8/18,20/07 On Saturday we cemented up the hole with 17 bags of portland. This should have brought the hole up to 650 feet. Today the hole was sounded at 642.5' There was about 7 inches of unset cement on surface. We used the dump baler and 3.5 bags of cement to bring the hole up to 620 feet. Tomorrow we will raise the hole to 615 feet. We will install at 612 feet on Wed. _______________________________________________ strain-int mailing list strain-int@pbo.unavco.org http://pbo.unavco.org/mailman/listinfo/strain-int From: Wade Johnson Date: August 22, 2007 9:33:07 PM MDT To: Strain , dreger@seismo.berkeley.edu, rich@seismo.berkeley.edu, nadeau@seismo.berkeley.edu Subject: [strain-int] B900 Blackwell 2 install report 8/22/07 Today we installed US39 at 611 feet in Parkfield area site B900.
