    Vessel Rupture (Fire)

    Hello All, I hope you can guide me on my way to find an answer. I need to calculate if a separator is going to rupture due to fire exposure. I estimated the temperature profile through time. I think I have to calculate the strength on the vessel to compare it with the UTS of carbon steel at...

    Flare piping design

    Latexman, I have read the posts and I confirmed this is a complex system. You mentioned that "the latent heat in the metal will transfer from metal to fluid". Is that involved in the calculation of the metal mean temperature? Because I am calculating the internal wall temperature (gas inside...

    Flare piping design

    Hello All, Please do you know how to calculate the mean metal temperature? I need it to determine the design temperature of the flare piping dowstream of the BDV/RO in case of depressurisation. Thanks in advance, Petroleo

    Shear Rate

    Hello All, I hope any of you can help on this. I need to calculate the shear rate in a pipeline at different flowrates of a mixture of gas and oil. I have read that I need the internal diameter of the pipeline, and velocities but I am not clear about the equation and if the velocities are for...

    heat exchanger

    Hello All, I have this info about an oil cooler: Size: 2.58ID 23 O/L Design T:120 S:155F & T:150 S:250 psig Oper. T:45/70 S:128/75F & T:100 S:186 psig It means, shell and tube type, but I need to know if it cah handle around 30 MBOPD? I think oil is flowing through tubes. Thanks in advance...

    Residence time calculation

    Thank you both of you for your responses. My real problem is to calculate the oil residence time and now I found out that Stokes Law would be apropriate. Do you know if there is a typical particle size of oil in water? Oil density is 810 kg/m3 and oil viscosity is 1.4 cp at Patm. I know it must...

    Electrical Oil Dehydrator

    Thanks a lot monaco8774, that was exactly the type of information I was looking for!

    Residence time calculation

    Hello All, I suppose this is a so simple question but I am afraid I do not know how to solve it. Could you tell me How I can calculate if the residence time in an existinting horizontal separator is OK? I have the dimensions and estimated liquid and gas flows. Thanks in advance, Petroleo

    Electrical Oil Dehydrator

    Hello All, Do you think it is possible to switch a conventional 1st stage separator with an electrical oil dehydrator? the dehydrator is 6 times bigger but I do not find technical information about its limitations. I mean what is the main characteristic of this type of vessel? The only info I...

    Topside Weight

    Thanks a lot monaco8774. I see that operational weight would be more representative if I need to calculate spare weight in a facility, isn't it? Thanks in advance, Petroleo

    Topside Weight

    Hello All, I am reading a Topside Weight Review and I need to know the weight for each piece of equipment. But only base dry weight / base operational weight ratios for 10000t topsides are reported. DO you know what is that? how can I use them to get what I need? Regards, Petroleo

    Pressure Drop

    Hello everybody, I am wondering what would be a suitable maximum segment size for a pipeline pressure drop calculation with pipesim package? is a 3% of the pipeline length a good criteria? Thanks, petroleo

    BHP behaviour

    Thanks cesarcf1977 for your comment, I completely agree with you, but if you fix the THP, GOR, Gas Lift and water cut, and increase the flow, I think BHP has to increase as well. I have notice that at low GOR (up to 500) and low gas lift (up to 1 MMSCFD) BHP decreases when production is...

    BHP behaviour

    Thanks zdas04, I am using Pipesim because I got some previous results with Prosper and BHP decrease appeared as well. I am just generating BHP behaviour at several conditions in order to evaluate future changes in fluid properties on the system. I agree it is a complex system but these results...

    BHP behaviour

    Hello all, I think when liquid rate increases, BHP should increase as well. The opposite behaviour could be seen when GOR or gas Lift increases, or when water cut decreases, isn't it?. But I am simulating several 12000-15000 ft depth wells, 30API and I am getting lower BHPs at higher liquid...

    well completion

    Hi DrillerNic Thanks for your response, it really clarify me a few stuffs that I was not totally sure about it. The problem really is the high water cut, so I think my best approach would be have a carefully look at the logs, and production test, to see if I can determine which is the zone...

    How to reduce water production

    Dear Colleague, I am looking for information in how to control water production. I have read a little bit of gel injection, a polymer that change the relative permeability in the reservoir allowing oil and gas to be produce, and blocking water, but beside that, I would like to know if you have...

    well completion

    What parameters could be changed in a well completion when water cut is getting higher? or you think only a change of pay zone would be a solution?
