Kansas City Company Uses US Product, TerraThane, to Keep Natural Gas Flowing in Nation’s Ninth Largest Gas Reserve

FORT LUPTON, CO—An unfortunate inlet line break at one of Anadarko Petroleum's hydraulic fracturing stations in Weld County, Colorado just north of Denver, allowed injection fluid to wash out the end of the pumping station and get beneath the concrete slab foundation causing erosion. The voids created beneath the slabs were from three inches to five inches and left the slab floor uneven. The general contractor for the station, Open Range Services, initially thought to use the legacy method [...]

Breakthrough! Bertha TBM Completes Alaskan Way Viaduct Tunnel in Seattle 

GeoPrac.net [2017-04-05 07:29:14]  recommend  recommend this post  (30 visits) info
After tunneling 9,270 feet under downtown Seattle, the Bertha tunnel boring machine finally broke through at the north portal yesterday. The breakthrough marks a major milestone in the project to replace the seismically deficient SR-99 Alaskan Way Viaduct. The 57.5 foot diameter machine started tunneling in July of 2013, and I was fortunate enough to take a tour of it shortly after that. The Seattle Tunnel Partners team ran into some major problems in January of 2014 when they encountered an [...]

Uncovering the Hidden Benefits of Buying New Software

A good way to begin building a business case for investing in new software and systems is to evaluate the time and cost in carrying out a typical task, such as producing site plans and geological profiles. Byrne Looby Partners have done just this and reaped significant benefits from using HoleBASE SI and the AutoCAD Civil 3D extension on The Irish Water projects. As Andy Wilkins says, ‘Everything we do now goes into HoleBASE SI and the Civil 3D extension as it is saving us and our [...]

Norway may build the world's first tunnel for ships 

GeoPrac.net [2017-03-30 08:04:15]  recommend  recommend this post  (59 visits) info
If Norway's Stad Ship Tunnel gets approved, it would be located on the Stadhavet Sea, an area known for heavy winds and hurricanes. Stormy weather makes it almost impossible for ships to travel in the area. Vessels often wait for hours or even days before it becomes safe enough to cross. A study has been performed by the Norwegian Coastal Administration (NCA), and their findings are scheduled to be released this May. If approved by the Norway Department of Transport, construction could [...]

Maybe I missed this when it first happened, but I recently saw that AASHTO's Standard Specifications for Transportation Materials and Methods of Sampling and Testing is no longer being offered as a printed book but now is a web-based publication with a single year subscription fee. It can get pretty pricey for multi-user license. I'm sure it's convenient, but if you are running an AASHTO accredited lab, you probably just have to bite the bullet. I wonder if all of their publications are [...]

Every tunneling machine needs its cutting tools replaced every now and then. But the challenge is keeping a giant machine sharp while a wall of waterlogged earth looms in front. Welcome to the world of hyperbaric interventions, where crews used compressed air to stabilize the ground and safely complete this high pressure work. This video takes you 200 feet underground for a rare look at hyperbaric work inside Seattle’s SR 99 tunneling machine, Bertha. [Source: WSDOT YouTube Channel. [...]

Earlier in February severe rain caused the Oroville Dam in Sacramento to reach capacity. The dam is an earth fill dam approximately 770 feet high, making it one of the tallest dams of this type in the Country. On February 11, water began flowing over the emergency spillway, which prior to that point had never been used, and caused erosion at the base of the weir, threatening to undermine the wall at the top of the spillway and potentially cause a catastrophic failure of the dam.
