  • Fractured Bedrock Remediation - Case Study

    ABSTRACT BOS 200® successfully remediates petroleum groundwater impacts in fractured bedrock at a former truck stop. Based on the post-injection groundwater results from the pilot test and full-scale injection, a No Further Action letter was issued in February 2015. CHALLENGES Over a period of 20 years, site investigation activities revealed a 320 foot ...

  • Hart`s E&P: Optimizing production, economics in mature fields

    To generate cash flow in low-price markets, operators have historically turned to the resource they can count on most—fields that have proved they can produce. But optimizing production from mature fields presents its own set of challenges that have the potential to offset the benefits of improved production with higher capital expense. Increasing production while lowering lifting costs and ...

  • 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 ...

  • Multipurpose Horizontal Remediation Wells Treat Impacts from Former DOD Operations

    The site, a former DOD plant previously used for the manufacture of aircraft and missile systems had TCE impacts that posed a threat to the current occupants at the site.    The site had been recently redeveloped into an industrial complex for several companies. For the new occupants, a disruptive indoor construction to install a vertical remediation system was out of the question. In ...

  • Ground Water Remediation Case Study

    The Pine Street Barge Canal Superfund Site is located along the coast of Lake Champlain. Sediments in the canal were contaminated by historic dumping of various materials including coal tar, solvents and petroleum products. Terra Contracting Services, LLC (Terra) was retained to implement the remedial design. Terra subcontracted with Global Environmental Engineering Inc. (Global) to provide ...

  • 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 ...

  • Green Buildings: Economics and Policies

    Introduction Green building has received increased attention over the past decade from both environmental economists and policymakers.

  • World Oil: Proppant-sized solid inhibitors improve flow assurance in fraced wells

    The economic value of a hydraulically fractured well is highly dependent upon flow assurance—that is, maintaining unimpeded flow of hydrocarbons from the formation to the surface. Flow assurance issues occur in hydraulically fractured wells, as a result of the deposition and buildup of naturally occurring particulates that are present in the system during hydrocarbon production. Scale is ...
