Being an experience Process Engineer I have been asked to Design a PLEM. First I got lost what is PLEM then found out What is PLEM. The datasheet given to me is entirly different than a Manifold data sheet. Appreciate experts help. I have been told it is for inhouse design and not for submission...
I have been asked to look for a suitable pump that can pump liquid from two phase separator to another platform. The production separator will be operating at 40 PSIG whereas the pump discharge reuirement is 140 psig. The amount of liquid is around 30,000 blpd (oil+water). Neither electricity...
Gentlemen,
The gas is wet, water saturated and a heavy gas, right out from Production Separator. The Separator is to be operated at 75 psig. The produced gas is transmitted to another Gas compression Platform. The Gas Mol weight is around 20.4, amount of the gas is in between 30 and 50 mmscfd...
By default I have become a project engineer for revisit of wells. The process engineers are doing blowdown calcs along with P&ID redline to connect the platform blowdown with the rig flare in addition to preparing the Long Leed Item list. Instruments is checking the available slots in pannels...
Gentlemen I have to maintain Normal level in a production separator. I am using a variable speed pump to draw the liquid and pump to a high pressure (from 30 barg to 100 barg). Normally, the liquid flow will remain constant with the exception when pigging operation is in progress. To control the...

The minimum length for a 6-inch launcher barrel should be 6 feet. For each pipe size above 6-inch add 1 foot (i.e., 8-inch should be 7 feet, 20-inch should be 12 feet, etc.)
I found the above statement while going through a search for a 20" Pig Launcher minor and major barrel length...
Considering the limited space available on an offshore platform the task is to design a 3-phase separator that can accomodate possible slug of well fluid. Options available are: (unless someone has better idea)
(i) Have a slug catcher followed by a separator, but this option requires a great...
I have done simulation on Hysim in 80s and then repeated on Hysis, sometime in 90s then never touched it. Now I have some time to polish up. I am looking for a solved model (oil Refinery, LPG, etc) that I can follow and polish up my rusted skill. Assistance will be appreciated.
A gas processing plant designed on international codes and standard, now it is to be changed to client Design Engineering Practices (DEPs). I would like to know what documents and drawing will require changes. I have to make a comparitive statement. Is there anyone who has such a matrix or...
Gentlemen,
We are in the process of installing gas compressors for Gas injection into wells at a pressure of 3000 PSI. In the design there was no backpressure PCV on the compressor discharge line, which compresses gas from 1400 psig to 3500 psig. In the HAZOP it was recommended that a PCV is...
In desinging a pig launcher I have provided a 2" balancing nozzle on the minor barrel which in turn is tied in to the kicker line (downstream of kicker isolation valve) for feeding. In some modles the balance line is tide in between major and minor barrels rather than minor barrel and kicker...
Gas Injection is to be carried out at 3000 psig by compressing the associated gases. SDV is proposed on the downstream of pig launcher (at plant) as well as at the upstream of pig receiver at well site on the gas injection pipeline. I am of the view that two check valves will do the job and does...
A 6” oil transport pipeline is being laid from point A, which is 18 km from the flow station. In the way, two pipelines from two different set of wells joins the transport line at point B and point C. The point B is 4 Km and point C is 13 Km from Point A. At point C the line dia is increased to...
Ladies and Gentlemen,
40 mmscfd-associated gas at 100 psig is to be compressed and supplied to LPG plant at about 1200 psig. Considering the possibility of LPG plant shut down the gas needs to be directed to gas injection well. This however will requires further compression, 3500 psig, to...
Production (Water, H/C Liquid and Gas) from a well is to be measured; a three phase metering system is one possibility but due to complications it is at low priority. The other possibility I am looking at is that the gas be separated prior to metering skid by installing a riser on the production...
In a production facility, the existing Overhead suction header (elevation: 9 ft) needs to be extended to accommodate two new pumps. The new pumps are bigger in size and to accommodate the valves and fittings the extended header is to be elevated by two feet (elevation: 11 ft). In other words the...
The well fluid at a pressure of 1100 psig and 90 deg F is fed to a scrubber. The gas quantity in the well fluid is 10.5 mmscfd whereas liquid is around 1200 BLPD (oil+water). The part of the gas at 1000 psig is to be used as lift gas whereas around 40% of the gas is to be fed back into...
High GOR together with small amount of sand has made a hole in wall opposite to inlet nozzle of a 10” production manifold. De-sanders are being looked into but it will take time. Meanwhile, better metallurgy is desired for the manifold to overcome the problem. I'll appreciate your...
I am having problem with the production manifold due to sand and high GOR from couple of oil wells, hooked up to the manifold. Can any one suggest the type of metallurgy suitable for fabrication of new manifold? The existing manifold is 300#, A-106 grade B, which has eroded. I was thinking of...
