  • Drilling Mud in Horizontal Directional Crossing Project

    Horizontal Directional Crossing Project has a not long development in the country and even the world. But in recent years, pipeline horizontal directional crossing has been great development, large-scale construction of oil and gas pipelines across the length and across the diameter of the continuous creation of new records. In horizontal directional crossing project, the drilling mud play a very ...


  • Horizontal Directional Drilling - A Green and Sustainable Remediation Remedy

    Interest in using sustainable practices and technologies for environmental cleanup has increased notably within the past few years. The US EPA and many states have published recommended practices to reduce the environmental footprint of cleanup operations, and many consultants and contractors are attempting to “go green” in contaminated site remediation. It makes sense to conserve ...

  • 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 ...

  • 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 ...

  • Evaluation of a Horizontal Well

    Background: Air Sparging Air sparging is an in-situ remediation technology where air is injected into the saturated zone of an aquifer. It is an alternative to conventional ex-situ pump and treat systems for remediation of contaminated ground water. It is necessary to understand the pattern of air flow that will occur in the subsurface in order to determine the optimal placement, ...

  • The “Straight Skinny” on bentonite-based drilling muds & their standard practice use in the horizontal remediation well industry

    Let’s make our point up front: 1) bentonite-based drilling fluid is NOT bad for horizontal remediation well (HRW) projects; 2) it does not damage the formation; 3) it is a naturally occurring clay material that is mined; and 4) it does flush easily/adequately during well development. Most remediation professionals have designed and/or installed vertical wells at one time or another ...

  • 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. ...

  • 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 ...

  • Horizontal Remediation Wells used in order to preserve military security

    Project Description: Remediate a plume of trichloroethylene (TCE) under multiple military buildings by air sparging (AS) and soil vapor extraction (SVE). There are two target zones: the shallow zone is approximately 70' below grounds surface (bgs) and 20' below this is the deep zone. The plume was located under multiple buildings comprising an area of approximately 150,000 SF. Scope of Work: ...

  • Direct-Push Injection and Circulation Biobarrier to Remediate a TCE Groundwater Plume

    ABSTRACT: The goal of this study was to determine if direct-push drilling methods combined with a circulation system could be used to establish a passive biobarrier in a very transmissive aquifer to treat tricholoroethene (TCE). The Site is located in central Indiana, where historic use of TCE has impacted an unconfined aquifer. A plume consisting primarily of TCE has migrated from west to east ...

  • DTI assists Samsung Corporation with innovative horizontal remediation well installation for the Yongsan District `Dream Hub` Project in Seoul, South Korea

    Site Background Dream Hub is a massive $40 billion redevelopment project in the heart of Seoul, South Korea encompassing an international business district spanning over 34 million square feet and hosting what is to be the tallest building in Asia, thus, landing Seoul on the map of cities with the world’s tallest skyscrapers. This substantial urban development will span over 140 ...

  • 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 ...

  • 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, ...

  • Plume Control under a City Building

    Subsurface remediation in a big city setting is complicated. Limited work space, heavy traffic, noise restrictions, and a dense network of utilities are just some of the factors that conspire to make the installation of any in situ plume control or plume reduction system a seemingly unsolvable logistical puzzle. Horizontal wells placed directly beneath a building can provide protection from soil ...

  • Plant Profile - Warrenton Wastewater Treatment Plant Sequential Batch Reactor

    The Warrenton (Ore.) Wastewater Treatment Plant is brand new. In fact, it initiated full operation Jan. 2, although the plant has been utilized since June 28, 2006. The sequencing batch reactor (SBR) plant was constructed on top of an existing facultative sewer lagoon site. The site conditions prohibited deep excavations, so the three basins for the SBRs are shallow, at only 12.5 ft (3.8 m), with ...


  • New advances in planning a bore

    Software helps take out the guesswork Horizontal directional drilling (HDD) is challenging and difficult work fraught with unknown obstacles.
