  • Maintenance of Oilfield Drilling Mud Decanter Centrifuge

    Decanter centrifuge is widely used in drilling mud separation to separate smaller solid particles after the equipment processing such as drilling mud shale shaker and drilling fluids mud cleaner or desander and desilter. Usually, decanter centrifuge is equipped with screw pumps or slurry pumps to feed drilling mud to ...


  • Degassing Refrigerators - Drill-head and Piercing-plier

    1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into ...

  • What`s at Stake: The debate over Arctic Drilling

    Royal Dutch Shell is planning to park two massive Arctic oil drilling rigs in Seattle's waterfront before they head north - but the petrochemical giant will first have to get around protesters in kayaks and others who want to thwart the new frontier in oil exploration and spark a national debate about fossil fuels and climate change. Here's a look at the debate over Shell's plans to drill in the ...

  • A new approach to drilling waste management – prevention!

    Grangemouth based Surface Active Solutions (SAS) has developed its microemulsion based technology to aid the prevention and management of drilling waste. The many activities surrounding the removal of drilling mud in surface and downhole cleaning applications usually generate significant volumes of oil contaminated drilling waste. The drilling mud is typically removed through the use of solvents ...

  • 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 ...

  • Comparison of core sampling and visual inspection for assessment of concrete sewer pipe condition

    Sewer systems are costly to construct and even more costly to replace, requiring proper asset management. Sewer asset management relies to a large extent on available information. In sewer systems where pipe corrosion is the dominant failure mechanism, visual inspection by closed circuit television (CCTV) and core sampling are among the methods mostly applied to assess sewer pipe condition. This ...

  • Perforation of ABS pipes by boring bivalve Martesia striata: a case study

    Acrylonitrile butadiene styrene (ABS) pipes are considered to be immune for boring organisms. However, inspection of the o0shore cooling water conduits of Lumut combined cycle power plant, Malaysia show that ABS pipes may not necessarily be immune for wood boring pholads, Martesia striata. M. striata caused heavy damage by drilling holes in ABS pipes used (about 5 years) for transportation of ...
