  • 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 ...

  • The use of the Pareto distribution for fracture transmissivity assessment

    For many applications data on the transmissivity distribution of individual fractures are necessary, i.e., discrete fracture network (DFN) modelling of groundwater flow and transport of solutes in fractured rock and design and performance of rock grouting. Using borehole data from the Äspö Hard Rock Laboratory, Sweden, it is shown that evaluated fracture transmissivities from three boreholes at ...

  • Portable Remotely Operated Drill (PROD): Hydrocarbon Sensing System

    Proven Technology Benthic’s prototype Hydrocarbon Sensing System (HSS) analyses drill returns for the presence of hydrocarbons as they pass through PROD before being vented on the seafloor. The System, in its present form, includes two hydrocarbon sensors in line with the drill returns path. Drill returns, composed of seawater drawn from above PROD and pumped down the drill ...

  • Railroad survey application

    Introduction The GPR technology has been introduced to the railroad engineers as one of the easy tools for quick and non-invasive railroad inspection. Since these surveys tend to stretch for a number of kilometers the amount of data can be overwhelming. However, with some clever preparations and proper tools for post processing the data one can create swift and easy to understand ...

  • 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 ...

  • A basic bottom-up approach for small systems of safe-water supply: a decentralized case study in Uganda

    In developing countries, diarrhea is known as the major cause of burden among children. Diarrhea is associated to poor quality of drinking water, inadequate sanitation and insufficient hygiene behavior. This work introduces a bottom-up approach for the implementation of a borehole installation in conjunction with proper water handling in rural areas. A pre-intervention survey was performed as a ...

  • 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 ...

  • Volumetric Analysis & Three-Dimensional Visualization of Industrial Mineral Deposits

    Abstract Base and precious metal deposits are typically characterized by a single parameter such as the total weight of mineable gold. Industrial mineral deposits, on the other hand, are characterized by their end-use. For example, the volumetric evaluation of a limestone deposit depends upon who’s buying the product. The concrete industry has a suite of evaluation parameters such as ...

  • Integration of Subsurface Data Management and GIS to Facilitate Model Calibration

    Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÒ Geology and any of several popular modelling environments ...
