  • Top Water/ Borehole Drilling Companies in Uganda (East Africa)

    Rural water being a source for health, an essential nutrient and a building block for peoples’ lives in local communities cannot be sustained without external support in form of boreholes as they are the ‘surefire’ answer to providing fresh water in rural communities. A borehole is simply a deep-hole or a shaft sunk into the earth purposed ...

  • Borehole Video Systems – Making A Difference…

    This article was originally published in the May 2009 issue of Geodriling International. Mike Deed, Managing Director of Geoquip Water Solutions Ltd, considers how the Laval R-Cam 1000 portable downhole video camera could revolutionise the borehole inspection industry. THE ability to see into a deep borehole has been an aspiration for well drillers, well owners, and geologists ...

  • 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 ...

  • Geodrilling International - Installation of Closed-loop Borehole Probes

    The installation of closed-loop borehole probes is a challenge on almost any project. With many domestic clients requiring a large meterage of borehole to be installed in a small site, Nicholls Boreholes has found that the traditional manual installation of closed-loop borehole probes is no longer a safe or acceptable option. The company has developed the Loop Feeder, a hydraulically-driven, ...

  • Effects of Borehole Fluid on Standard Penetration Test Results

    The standard penetration test (SPT) represents the most widely used in-situ test method for evaluating the liquefaction resistance of saturated soils. Significant progress has been made in recent years in developing correlations between SPT results obtained using different test procedures and equipment in order to develop a higher degree of standardization for SPT testing. One of the heretofore ...

  • 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 ...

  • 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 ...

  • The application of high pressure jetting drilling in Eastern Sichuan

    Based on the problem of the low rate of penetration (ROP) of well sections above Xujiahe formation (mainly sandstone and mudstone) in Eastern Sichuan, Southwest of China, this paper discusses the feasibility of a high pressure jetting drilling scheme in this area and analyses its mechanism of increasing ROP. The paper establishes a physical model of borehole flow path at bottom hole and applied ...

  • Why Bentonite Hurts Well Production: The Case for Biopolymer Drilling Fluid

    Bentonite is a naturally-occurring clay material, largely composed of the mineral, sodium mont-morillonite. The dominant property of bentonite is that it swells to many times its dry volume when hydrated by water, forming a viscous fluid with high gel strength. This makes bentonite an excellent product when used as a sealant, for preventing the influx of surface water into a well, sealing ...

  • Using the Pencil-Paper Method with a Tablet Computer to Increase Borehole / Well Logging Efficiency

    Traditionally, geologists use pencil and paper when logging soil descriptions, drilling tests, and well diagrams in the field.  We wanted to see if we could speed up this process using a field computer.  We tested a fully ruggedized Yuma2 tablet computer (retail value of $3500) and a consumer grade Dell Venue 8 (retail value $250).  Both computers run a full version of Windows 7 or ...

  • A novel approach for providing potable water in rural Sodwana Bay, northern Kwazulu-Natal, South Africa

    Many people living in the Sodwana area of South Africa do not have access to potable water. Groundwater is the best source of fresh water for the rural community. Potable water in the Zululand coastal plain, Sodwana, South Africa can be enhanced by: (i) providing detailed information on the aquifer system using geophysics; (ii) providing information on groundwater quality and its efficient ...

  • South East framing review

    Drilling a borehole on a farm can cost less than a conventional water supply and cut the carbon footprint from pumping and treating mains water. "There is an environmental as well as a cost argument for drilling a borehole,' said Ben Nicholls, joint managing director with his brother Richard of Nicholls Boreholes, which is based in West Sussex. Nicholls Boreholes is in an office on an ...

  • Bridge/tunnel base exploration case study

    Case 1 A surface-borehole resistivity survey completed for bridge construction As shown infigure 1, this surface-borehole survey was configured to accurately locate known caves for structural reasons. The operator collected 60k data points in only one hour as a result of how the FlashRES-UNIVERSAL can collect all voltage readings for each combination of current electrodes. Figure 2 shows that the ...

  • 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 ...

  • Horizontal Wells - Technology Overview

    Horizontal well technology has been incorporated into many current environmental remediation applications (and associated contaminants), such as in situ bioremediation, air sparging, vacuum extraction, soil flushing, free product recovery, etc. Ac cording to information reviewed, this technology is most applicable to sites with relatively shallow soil and/or groundwater contamination, and can ...
