  • Case Study: Why Horizontal Ozone Sparge

    To avoid costly business interruption and site disturbance, Ganesh Kurse with G & RK Consulting Associates, recommended a non-invasive remedial approach by installing horizontal ozone sparge wells with directional drilling techniques. Although horizontal ozone sparging wells were a new remedial technology to G & RK and the State of Alabama’s underground storage tank (UST) ...

  • Cost Effective Multi-Purpose Horizontal Wells

    A question commonly posed to Directional Technologies from our environmental consulting clients: “Can one horizontal well be designed for more than one remedial application?” The answer is “yes.” Horizontal wells are utilized for many diverse remedial methods: air/oxygen/ozone sparge, soil vapor extraction (SVE), multiphase extraction (MPE), in-situ chemical oxidation ...

  • 30" Sleeve Installed with Directional Drilling Underneath Highway

    “Taking time to properly plan and execute a horizontal drilling and utility installation project can save client’s monetarily by avoiding road closures and other costly delays typical with trenching,” said Mike Bertram of Directional Technologies. “We know that  Directional Technologies has the right personnel in place and they are using the best horizontal drilling ...

  • The Power of 243 Vertical Wells

    This is a comparison of a Horizontal Remediation System and a Verticle Well System at a theoretical site with an area of 388,800 ft2   where with a Radius of Influence (ROI) of 20 feet, 12 Horizontal Remediation Wells, depending on plume geometry, can cover the same area as 243 vertical wells with the same ROI per well. Not only ...

  • Horizontal Well Systems for Improving Remedial Efficiency and Zone of Influence

    To improve remediation efficiency and expand the zone of influence, Directional Technologies, Inc. transferred technology from the oil and gas industry to the environmental industry. The oil and gas industry has used directional drilling for decades to improve oil recovery, based on a simple concept that the more screen contact there is with the “pay-zone,” the more production gained. ...

  • Carbon Tetrachloride Source Remediation in Bedrock and Overburden - Case Study

    ABSTRACT Carbon Tetrachloride source in bedrock and collateral contamination in overburden were successfully remediated at a decommissioned U.S. Air Force base. CHALLENGES The combination of bedrock and overburden Carbon Tetrachloride (CT) contamination posed a unique set of challenges including the selection of an adequate drilling program, gathering ...

  • PRB Installation at Superfund Site Using Angled Drilling - Case Study

    ABSTRACT BOS 100® was injected adjacent to and beneath a stream using a direct push angle drilling technique to successfully create a PRB and limit PCE flux from the upgradient source area into the stream. CHALLENGES The Superfund site is a former textiles facility where tetrachloroethylene (PCE) was used in dry-cleaning operations. Approximately ...

  • When to Rent or Buy Tric Plumbing Equipment

    Without any doubt, Tric plumbing equipment is a new era in tric tools. So, what do the letters Tric stand for? They are used to mention trenchless plumbing equipment specially invented for the pipe bursting process that gave birth to the today trenchless home sewer replacement industry. Where should I rent or buy Tric plumbing equipment? Today, autonomous sewer ...

  • Hart`s E&P: Smart drillpipe technologies for the driller’s toolbox

    Advances in technology boost successful development of new LWD and drilling technology offshore the Norwegian Continental Shelf. Wired drillpipe (WDP) technology was implemented on a multiple-well project located offshore the Norwegian Continental Shelf. The operator’s main objective was to drill each well as cost-effectively as possible while making sure that the wellbore placement ...

  • Key Elements of a Successful Horizontal Remediation System

    Environmental remediation professionals around the country (and internationally) are rapidly learning that Horizontal Remediation Systems are an essential “tool in their remediation toolbox”. When designed and executed by experienced horizontal environmental drilling experts, Horizontal Remediation Systems can be extremely effective at achieving rapid site closure compared to vertical ...

  • Soil and Ground Water Remediation Case Study

    On this State Funded Clean-Up project, Global was the project engineer and was responsible for the design of an air sparging/soil vapor extraction remediation system. The system included five soil vapor extraction wells and twelve sparging wells that operated on a rotating schedule. One of the soil vapor extraction wells and nine of the sparging wells were installed as horizontal wells beneath ...

  • 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 ...

  • Direct and indirect effects of petroleum production activities on the Western Fence lizard (Sceloporus occidentalis) as a surrogate for the dunes sagebrush lizard (Sceloporus arenicolus)

    The dunes sagebrush lizard (Sceloporus arenicolus) is a habitat specialist of conservation concern limited to shin oak sand dune systems of New Mexico and Texas. Because much of the dunes sagebrush lizard's habitat occurs in areas of high oil and gas production, there may be direct and indirect effects of these activities. We used the congeneric Western fence lizard (Sceloporus occidentalis) ...
