  • Directional drill resale values and how to get the most for your rig

    Wide resale value disparity among brands There’s a lot to consider when purchasing or leasing a horizontal directional drill — features, durability, support, training and overall value. But one area often overlooked is the potential resale value of the unit. Too often contractors will overlook the potential value of the machine after its useful life in their ...

  • Modeling emissions from offshore drilling

    To regulate drilling activities proposed by oil and gas companies in the oil-rich Gulf of Mexico (GOM), governing agencies require the submittal and approval of certain plan documents before drilling activities can be initiated. For drilling activities in the Western GOM, these plans typically consist of one of the following: EP, or Exploration Plan – required to conduct ...

  • Centrifuge Technology in Drilling Fluid Recycling

    Drilling fluid additives and the water that contains them are an essential part and expense of successfully completing a horizontal directional drilling (HDD) installation, and the longer the bore and larger the product being installed, the more drilling fluids cost. Therefore, it makes economic sense to recycle drilling fluids by removing cuttings and recirculating the cleaned ...

  • Q&A: A look at Shell Oil and Arctic offshore drilling

    Shell Oil drill vessels are heading to the Arctic. But they will not be permitted to drill into petroleum-bearing rock until a key piece of blowout response equipment, a capping stack, is on site. The capping stack is carried on the icebreaker Fennica, which arrived early Saturday for repairs in Portland, Oregon. Arctic offshore drilling opponents plan to demonstrate while the Fennica is ...

  • Principles of HDD Solids Control & Buyers Guide

    Relative to the use of drilling fluids within the oil & gas industry, the use of drilling fluids within the horizontal directional drilling (“HDD”) industry, is new.   As the use of HDD technology did not become mainstream until the 1980’s, it took another decade before drillers started to consider the use of basic drilling fluids.  Even today, ...

  • Common challenges relative to the use of Decanter Centrifuges for barite recovery in the oil & gas industry

    When centrifuges are properly deployed, they can have dramatic effects on drilling performance. In fact, without them, many of the advances made in drilling would not have been considered achievable. Classically, we believe that centrifuges can achieve two common goals: Reduce the content of drilled fines, specifically colloidal solids, and Perform barite recovery in order to reduce ...

  • Oil shale is not a viable fuel source - Study

    While many are celebrating the end of the 'Peak Oil' concerns because of abundent new sources of oil in shale deposits, a true accounting for all economic and environmental costs to exploit this energy source suggests it may not be a viable proposition at all. Scientists' best estimates of the Energy Return on Investment (EROI) of oil shale suggest it is very inefficient compared to conventional ...

  • ISCR-Enhanced Bioremediation Accelerates Groundwater Cleanup at Active Manufacturing Facility

    In the winter of 2008, full-scale in situ chemical reduction (ISCR) was implemented as a removal action at the Siltronic Corporation site in Portland, OR, to treat a source area contaminated by releases of TCE. The source area was considered to be the portion of the site with concentrations of TCE in groundwater greater than 11,000 µg/L, suggesting the ...

SOLUTION MACTEC evaluated various monitoring  technologies and determined that  Westbay System modular ...


  • Why many experts missed this: Cheap oil can hurt US economy

    WASHINGTON (AP) - If there was one thing most economists agreed on at the start of the year, it was this: Plunging oil prices would boost the U.S. economy. It hasn't worked out that way. The economy is thought to have shrunk in the January-March quarter and may barely grow for the first half of 2015 - thanks in part to sharp cuts in energy drilling. And despite their savings at the gas pump, ...

  • Danger and Detection of Hydrogen Sulphide Gas in Oil and Gas Exploration and Production

    A rig worker smells rotten eggs near the well head, rubs his itchy eyes as he investigates the frosty pipe connections. After a few moments, he believes all is fine as he no longer smells the tell-tale hydrogen sulphide odour. In this scenario, we can only hope the worker recognises the danger and quickly leaves the site. Oil fields, especially mature ones, can produce hydrogen sulphide gas ...

  • Triad expedites brownfields redevelopment in Fairbanks

    The Fairbanks North Star Borough (FNSB) used Triad in 2006-2007 to assess environmental conditions at a municipal property along the Chena River in Fairbanks, AK. FNSB accelerated the site investigation as part of a brownfields assessment grant received from the U.S. EPA in 2005. Low-level contamination had been identified onsite in past investigations, but its extent and impact on future ...
