Gents, Thanks for the replies.
The problems faced by me against the solutions-
Flame arrestor gets clogged over a period of time. Again how do we maitain the flame arrestor on a 200 feet vent stack of 8" diameter pipe??
The pressure from the compressor seals is too low & hence the same is...
Has anyone experienced vent stack fires at offshore platforms during thunderstorms????
My case is with around 0.5 MMscfd discharge through the vent to atmosphere- the source being mostly purge gas & leak from compressor seals.
What is the solution to prevent such fires??
Please refer the book " Reservoir Formation Damage" by Faruk Civan ( professor-university of Oklahoma). The book is published by Gulf publishing company.
What's is the basis for material selction in case of RF or RTJ flanges?? The problem faced is excessive corrosion at offshore location on the carbon steel flange faces.
Do we have a standard guideline/code for the gasket material selection??
Dead legs are a havoc to burst out in future. It will make life miserable once the facilities start ageing. Having a spare stub or a valve & not using the same will only corrode the same. Adding a flushing program doesn't work much. The microbial SRB's work 24/7 & our flushing program works once...
Dear fellow engineers,
Please enlighten with the standard practice for a Jack up Rig move IN /OUT to a producing offshore platform.
Is it a standard practice to shut-in all the production including the wells & depressurise the pipelines while the Rig moves IN or OUT of the platform???
OR Will...
Hi Unotec,
This is old data from Kermit E Brown hand book on Gas lift-
Normal temperature expected in a New Well along Texas & Louisiana Gulf Coast.
74 deg F +1.6 deg F /100 feet.
Example-
Given a 10,000 feet well. What temperature is expected at bottom?
74 def F + 1.6 deg F X (10,000/100)= 74...
my small piece.....
Normal formation pressure is equal to the hydrostatic pressure of the fluid extending from the surface to the subsurface formation. Add surface pressure if any.
Hydrostatic pressure psi= Density X0.052 X true vertical depth;
Hydrostatic pressure is defined as the pressure...
Dear fellow engineers, I have few queries on the usage of chemicals for day to day production.
1)Anti freeze chemical- like methanol/MEG ( glycol): This chemicals are injected along with gas in the well casings as well as on the trunk line to inhibit freezing. Does the excessive usage of...
Dear fellow engineers.......
I would like information on scale squeeze performed on oil producers to prevent scaling of the sub surface & surface equipment.
**What is the best combination of chemicals to be used?? Best recipe which will give a prolonged scale treatment?
**What is the best soak...
Hello all fellow engineers,
My problem has been the accuracy in well testing at the offshore location & this has resulted in problems with forecast's.
The oil producer via the test header is lined to a 2 phase separator & the outlets join each other ( Gas phase + oil & water) before exiting to...
