Axetris Sensor Field Test

The Axetris LGDs were operated continuously for two years. After intensive laboratory testing, they went out into the field in 2015. Axetris was able to test the functionality of its sensors under real-life conditions thanks to the support of the Linth waste incineration plant. The gas concentration measuring devices called laser gas detectors ( ...

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 ...

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 ...

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 ...

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 ...

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

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 ...

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. ...

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 ...

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 ...

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 ...
