  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • GPS-enabled gas analyser finds & proves borehole locations case study

    Prove it? They can now! Landfill technicians and environmental consultants can now find and prove borehole locations with a GPS-enhanced portable gas analyser from Geotech. Its on-board GPS guidance system takes staff to the precise location of the 1000 it can store. It adds the GPS-received location, date and time to the gas analysis record. GPS locations can be added at boreholes or pre-loaded ...

  • Isolate & sample up to 7 zones in one borehole

    CMT Multilevel Systems isolate and monitor up to seven discrete zones in one borehole; monitor 7 zones in the 1.7" (43 mm) System; 3 in the narrow 1.1" (28 mm) System. Both options are low cost. The single tube design makes them fast and easy to drill and install in one day. System flexibility allows port locations and monitoring strategy to be finalized right on site. CMT wells are ideal for ...

  • Scanning proposed borehole locations for Utilities case study

    Environmental and engineering firms often are tasked with performing soil borings for monitor well installation as part of a Phase II Environmental Site Assessment. This task becomes more challenging when the borings are to be installed in gasoline stations, right of ways or other areas where there are numerous underground utilities that are either unmarked or not properly located. GeoView can ...

  • Flow measurement technology comparison: GA5000 Vs Hot Wire Anemometer

    A typical landfill or contaminated land site under investigation will comprise of a suitable number of gas monitoring wells, with a planned series of monitoring visits.  The monitoring will include gas flow measurements, which together with methane and carbon dioxide concentrations will be used to calculate gas screening values (GSV) and hence allow the determination of whether any gas ...

  • Using Grid Tools in the RockWorks Utilities to Modify a Borehole Manager Stratigraphy Model

    Summary Creating a geological model with RockWorks can be tricky with certain datasets. When a Stratigraphy Model is created in the Borehole Manager, the program creates a top and base grid for each unit listed in the Stratigraphy Table. After model generation, you can view these grids, stored in the Project Directory, in the RockWorks Project Manager. The following steps demonstrate how you ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

  • Drilling Muds and Drill Cuttings Recovery for Beneficial Reuse

    Drilling Muds Drilling mud, also known as drilling fluid, is a vital component of the drilling process. It helps in the process of drilling boreholes into the earth where holes are required for extraction of oil and gas, core sampling and various other purposes. It is broadly of three types, including water-based, oil-based, and synthetic-based. Among all of these, synthetic-based muds ...

  • Triaxial permeability testing and microstructure study of hard–to–drain coal from Sydney Basin, Australia

    Several mines operating in the Bulli seam of the Sydney Basin, Australia have coal seam zones that are difficult to drain. Metropolitan Colliery being one of such mines, has experienced difficulties in reducing gas content within the available drainage lead time; as the coal seam would not drain even with additional drainage boreholes. A research study using coal permeability testing and ...
