  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • Optimising laboratory environment for successful IVF

    The London Women’s Clinic in Cardiff (LWC Wales) is one of ten clinics within its group which collectively provide expert fertility treatment to families across England and Wales. When it comes to IVF and fertility treatment there is no ‘off-the-shelf’ or ‘one size fits all’ solution and, as such, the medical teams produce a bespoke fertility programme for each and ...

  • Analyzer underpins growth of container inspection company

    After a career as a customs officer in the Netherlands, Wim van Tienen was well aware of the toxic gas hazards presented by some freight containers, so in 2009 he started a company, Van Tienen Milieuadvies B.V., offering gas analysis and safety advice. The company grew quickly and now employs 23 staff. Wim attributes a large part of this success to the advanced FTIR gas detection and analysis ...

  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • A Portable High Speed Gas Chromatograph for Field Monitoring

    Over the last two decades a variety of portable or transportable gas chromatographs (GC) have been specifically designed for field use. Each instrument has introduced innovations that have simplified the task of on site air monitoring. Portable instrument users are well aware of the advantages of field sampling. These advantages include more representative results because there is no sample ...


  • Baseline groundwater quality in unconventional oil and gas fields

    In recent years, expansion of unconventional oil and gas production has prompted significant interest in potential impacts on drinking water resources. In many cases, water quality investigations rely on access to landowner water wells to develop baseline data prior to drilling; respond to spills, complaints, or incidents; or evaluate potential impacts due to drilling, completion, hydraulic ...

  • Exergy of natural gas flow in Iran's natural gas fields

    Natural gas flow has a valuable pressure exergy which is currently destroyed in throttling valves at exit of the gas fields. In the current study, this pressure exergy has been calculated for an actual case. Exergy analysis was based on actual condition of the Shanol gas field, which is situated in Iran, in the summer. It is assumed to be a good representative of Iran's whole gas fields. Exergy ...

  • Leveling the carbon playing field

    Climate change is one of the most far-reaching economic challenges of our times. Unchecked, it threatens the welfare of people around the globe. Mitigating the worst of its impacts will require mobilizing capital and technology in innovative ways that will transform the global economy. The good news is that if we do it right we can generate technologies and markets that will not only leave us a ...

  • Evaluation research on performance of permeability and fracture in Sulige gas field by new method

    Tight gas is the most available alternative unconventional natural gas in China. Its potential is huge and the Sulige gas field is the biggest one. However, there are many urgent development problems to be solved, and evaluating well performance is of one of them. Low permeability, strong stress sensitivity and hydraulic fracturing make it difficult to predict well performance. Evaluating the ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

  • Field scale and economical analysis of carbon dioxide, nitrogen, and lean gas injection scenarios in Pazanan gas condensate reservoir

    Liquid dropouts around the wellbore in gas condensate reservoirs causes severe reductions in gas production rates, the permanent loss of a large portion of volatile and valuable condensates, and a wrong estimation of well deliverability. It is believed that applying diffusion coefficients and the Generalised Pseudo Pressure (GPP) method leads to more accurate modelling of reservoir performance. ...

  • Successful Dunbar Field Life Extension

    The advent of high-power multiphase pumps is changing the world of oil production. In particular, they allow continued production from fields that are nearing the end of their useful lives. These revolutionary pumps have been in operation since autumn 1999 on the Dunbar platform, in the UK sector of the North Sea. Multiphase pumping (MPP) is essentially a means of adding energy to the ...

  • Field Performance Testing for Pipeline Pumps

    Significant energy savings can be achieved by optimizing pump operating efficiency. Measuring the exact pump performance with crude oil under realistic conditions in the field is the first step towards improving the pump efficiency in the future. About 20 billion barrels of crude oil were transported through pipelines in 2015. Around the world, there are over one million kilometers of ...

  • Field verification of on-line hydrocarbon dew point measurements

    Introduction The Michell Condumax II applies a fundamental measurement principle for direct measurement of hydrocarbon dew point. Measurement performance is assured through comprehensive factory test and calibration, to verify that each analyzer offers accurate determination of the temperature at which hydrocarbon condensate forms. Further extensive examination confirms highly sensitive ...


  • Numerical modelling of gas dispersion from road tunnels in urban environments: comparison with field experiment data

    Numerical computations and field experiments of the dispersion of a tracer gas from a road tunnel in Paris are compared. The Reynolds-averaged Navier-Stokes equations, combined with the k-ε turbulence model of Chen and Kim, are solved using the finite-volume code PHOENICS. Results are shown to be sensitive to the turbulence modelling and to the parameterisation of turbulence and drag forces ...
