Are there any Stoner Pipeline Simulator users out there and what version, Gas, Liquid or Both?

RE: SPS
RE: SPS
I'm still running a 10-year-old copy of MNET from Scientific Software Intercomp (now defunct) with probably the last functional dongle. Like Stoner, it will handle just about any piping configuration and as big a model as you can code so I haven't felt the need to buy one of the new sexy programs.
I spent last week trying to make a 32 well, highly looped, low-pressure gas model converge in PipePhase. What a horrible experience. If you don't guess the flow direction properly then you get really bad results that aren't obvious until you do a line-by-line analysis.

RE: SPS
Thx for responding.
Ugh! I appreciate your pain. Is PipePhase doing 2-phase flow?
I've been using versions of SPS since the old mainframe version in 1986. I worked in a gathering system with 862 wells, many loops, multiple outlets and lots of field compressors inside. Never had any convergence problem. SPS usually works very well, once you get the model running, but that is generally not easy and always results in the addition of a few thousand gray hairs. Maybe that's a good thing... if you're bald. It always seems to be accurate. It is best to start with a microsystem and add on to it, one tiny little bit at a time, get that working and add on again. Lately one of my clients and I (or is it just me?) have been having trouble modeling dispersion between liquid batches. I was thinking about getting one myself someday, but price is relatively prohibitive ... so all of this has got me thinking. Seems like Energy Solutions TG/TLNET might be a real nice candidate. I have doubts about AFT, but admit I have not even researched its capability at this point. I don't know if it will do transients and heat txf to soil either. Still got some studying to do before I can think about opening up the billfold.
RE: SPS
I think PipePhase claims to be able to do gas, liquid, two-phase, but I'm a low-pressure gas guy and haven't had much need for rigerous liquids handling.
I don't recognize the AFT name.

RE: SPS
I preferred Pipeflo (it did cool down calcs as well, which were useful), but the windows style graphical user interface for PipeSim was easier to use than the screen input style interface on Pipeflo (but it was a few years ago, so Pipeflo may have changed!). But I seem to remember it didn't have that many multiphase flow correlations/ flow maps.
I know SLB have expanded the downhole aspect of PipeSim- tubing lift curves and the like- so I guess that's useful for modelling entire gathering systems!
RE: SPS
One thing I have learned to appreciate is a good graphical interface. I've done some of that with my old company for attaching to their SPS can. That is still something SPS has yet to learn. Theirs is too obviously an adapted front end fitted to the hulky old "C" engine. And, IMO, they forgot what all liquid pipeliners need most, graphical tanks. Shows that its the gas companies they rely on the most. I had to custom build my own trank graphics ActiveX and add it into their tool collection.
Well, I better decide fast. I said I can already do this kind of stuff on my web page. Later!

RE: SPS
I have used AFT for fluids for many years and get good back up. I am not a gas or two phase fluids designer so dont know the capability of the software. the engineers at AFT did come out of NASA. I find them to be straight shooters.
They also do consulting work so perhaps they can give you some references of gas jobs they have done and the clients you could talk to.
