  • 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 ...

  • Oil and Gas Development - Onshore Industry - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • Drilling Mud in Horizontal Directional Crossing Project

    Horizontal Directional Crossing Project has a not long development in the country and even the world. But in recent years, pipeline horizontal directional crossing has been great development, large-scale construction of oil and gas pipelines across the length and across the diameter of the continuous creation of new records. In horizontal directional crossing project, the drilling mud play a very ...


  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

  • Finding a Stable Operating Cleaning Regime - BWRO Plant - Cleaning Case Study

    Introduction A brackish water reverse osmosis plant (BWRO) in East Spain suffered a significant loss of performance, with permeate flow rate dropping 40% with a consequent drop in recovery from 65% to 45%. After unsuccessful cleaning attempts, Avista Technologies was approached to help the client remediate the system and to find a stable operating regime. This case study outlines how ...

  • In-depth analysis of changes restores system optimization - Case Study

    Introduction A reverse osmosis plant (BWRO) had been operating effectively applying Avista antiscalant and cleaners for about a year. Increased product water demand led to changes in the feed water quality and an increase in plant recovery resulting in an increase in stress on the pre-treatment system and more rapid membrane fouling. The existing membrane cleaning regime was reviewed to try ...
