'Upstream' in used to describe the processes involved in obtaining crude oil and gas from natural resources. This is likely to involve the exploration of potential gas and oil sites, using seismic and geophysical surveys alongside prospective drilling to determine whether or not a reserve has any promise. If a reserve is found, then the 'upstream' category also includes the development of oil or gas fields by doing things such as constructing well-heads and implementing production facilities.

The 'downstream' category covers processing the crude oil into a marketable product. This may include the transportation of oil and gas, using pipelines and pumping systems, as well as the procedure involved in resource liquefaction and gas processing, using oil refineries and petrochemical plants.

The oil and gas industry are driven by a series of demands, most notably the increasing demand for these resources, the increasing demand or products derived from these resources, new discoveries of oil and gas in complex natural structures, environmental concerns which have lead to specialist technological advances and new regulations which have driven the expansion and development of these industries.

The largest producers of oil and natural gas are Saudi Arabia, Russia, the United States, Iran, China, Mexico, Norway, Venezuela, the UK, Canada, Algeria, the Netherlands, Indonesia and Uzbekistan. However, there is an increase in production from offshore areas such as the Gulf of Mexico, the North Sea, Angola, Vietnam and Australia.

There are many oil and gas jobs available and they can offer successful candidates a truly international career. Oil rig jobs can take a UK engineer to offshore areas across the globe, whilst drilling jobs are available in new and emerging hotspots, such as Kazakhstan, Azerbaijan and Turkmenistan. These will all require 'upstream' teams to assess the area's prospects in the initial stages, as well as 'downstream' engineers, planners, sales and marketing staff, accounts advisors and construction engineers - to name but a few involved in these mammoth processes.

Those seeking oil and gas jobs overseas would be ell-advised to utilize the services of an appropriate recruitment organization. These groups not only have advanced notice of jobs 'in the pipeline', but they also have the contacts in the industry that ordinary people do not have access to and the capabilities to ensure that the right CV is seen by the right people.

Working abroad in this industry is a chance to begin a new life and enjoy a global career with good work prospects. The demand for gas and oil is relentless, opening up job opportunities within every sector of the processes involved in finding and harnessing these natural resources.

Our compressor vendor is currently supplying a screw compressor package with a 25% capacity recycle valve and not 100% - they have stated that this is typical practice. The screw compressor responds to high discharge pressure by using it's slide vane to unload the screw, then reduce speed and then open recycle. The slide vane takes some time to respond and unload and I am concerned that it will not be quick enough to avoid tripping the screws on high discharge pressure. Immediately opening a 100% recycle valve and unloading the screw as quickly as possible makes more sense to me and I am wondering if we are wise to get the vendor to upsize the valve for this purpose?

Anyone have any experience with operating screws and recips in series in close proximity?]]> http://campbellforums.com/discussion/75/dehydration-by-cooling Mon, 10 Nov 2008 14:30:47 -0700 Miguel Araque 75@/discussions

I am a french junior process engineer working in an Engineering Company.

The context is the following:
- The system is: inlet pipe + control valve + outlet pipe.
- The fluid is natural gas
- The outlet pipeline is burried.
- No outlet pipe insulation.
- The minimum allowable temperature in the outlet pipe is -20°C.
- The minimum temperature at the control valve outlet flange is about -15°C (worst scenario)

The problem is that i need to calculate the length of outlet pipe so that the fluid temperature increase to 0°C.

My data are:
- Outlet pipe material: carbon steel (L360)
- Outlet pipe internal diameter: 570 mm
- Outlet pipe thickness: 20 mm
- Outlet pipe is burried 1 m deep.
- Average air temperature: 11°C
- Wind velocity: 10 m/s

My questions are:
1/ Do you know where i can find thermal conductivity data for ground? or do you have data? I know it strongly depends on the ground composition but i don't have anything...
2/ Could you please share any Excel spreadsheet to perform that calculations?

Thank you

OR say I am a bad Guy who want to create hydrate in a flow line of well whose pressure is say 3000 psi.

Its 100 % methane....now when I open the choke valve, due to pressure drop accross the valve temperature will drop...but at the same time if i open the choke fast then pressure drop will be minimize ....can i avoid hydrate formation by this way or I will end in to a trouble.

kindly explain.

I can see the hydrate curve and I can know the P and T for hydrate formation but I want to know due to my mistake I will end up in such situation...

Also if the upstream of choke is gas and downstream of choke is nitrogen in that case also if pressure drop is there then hydrate will form or what ?

also if line is full of seawater and nitrogen then addition of methane gas will form hydrate ?
