Slow oil field? Bad plumbing?

[zOldBulldog]

I just started producing this oil field. I would swear all my previous oil fields (even smaller ones) filled the tanks much faster (at least before the field goes down to a trickle) even before adding speed modules and beacons (like in this case).

I am sure I messed up the plumbing somewhere but I can't spot it. Can someone see where I got it wrong?

Thanks in advance.

EDIT:

Here is the resulting layout after implementing the changes suggested.

I will have to update my "oil field loading station" blueprint to match this. It is better than what I had.

Easy way to tell if your pumpjacks are connected or not: watch them for a bit and see if they all continue to animate. If some of them stop, those ones aren't connected to the rest of the system (and have now filled up their pipes with oil). Also, what is the yield of that entire patch, according to the map? (Gives an indication what level of throughput you should expect).

[orzelek]

You have one disconnected underground pipe behind med pole along the vertical pipline that collects the oil. Thats only from one pumpjack so shouldn't make big difference.
Check the oil fields - maybe they rolled pretty low.

Also you can try to place the pump between left side tank just next to it.

One thing that might help overall is not trying to place all oil wells on one line to tanker - connecting them in groups to separate inputs should make things faster if pumpjacks can produce a lot of oil.

Thanks frightning and orzelek, that helped.

The pumpjacks are showing expected resources to be: 13.4/s, 18.0/s 18.4/s, 20.5/s, awa20.7/s, 21.6/s, 22.1/s, 24.1/s, 24.2/s, 26.0/s. All show productivity +22% at the moment. Combined yield for the field is 2094%.aw

@orzelek:
- I moved the pump between the collection tank on the left and the loading tanks to being attached to the collection tank as you suggested.
- If I'm looking at the right pipe behind the medium pole of the line that collects oil, that is not disconnected just an underground pipe I used to allow me to walk through.
- I think you are right, using separate pipelines for the tanks would probably move the oil faster... on the other hand I am wondering if it might be overkill by the time the field goes down to a trickle. After the initial slow fill, it seems to keep up with the 2 trains I allocated to this field. But I am definitely going to do that with the next field, it has a lot of oil patches and combined yield of 16,899%. What do you think?

@all:

In order to determine how many pipelines I should plan for on a big oil patch, is there a way to calculate how many/which pumpjacks to put in each pipeline so that it doesn't slow down due to being full?

If you place a pump at the end of the line to force it into storage tanks, you only need 1 pipeline to support up to around 10000% yield. In other words, don't worry about it. I use pipelines instead of setting up a 30 second train route. The pipes don't really care.

Thanks bobuckles, implented (I hope ) . I added an updated screenshot on the original post.

[orzelek]

If I'm seeing correctly your updated screenshot still has the initial issue
Circled it here:

There is an underground pipe that ends at the same point where your walk through short underground starts so there is no connection there.

I see that now, thank you!!! I will fix it as soon as I get back home.

Edit... and done! Thanks again for pointing it out.

Yeah, my rule of thumb, assuming the oil patches are at least 100%, is 3-4 pump jacks per pipe if at all possible. No math on my part, just seems to work well enough for me.

Rules of thumb are good, they don't hurt my brain

And I assume the rules extends to 3-4 per pipe, up to a total of 3 pipes per wagon max (one per tank/pump going into the train)... at which point let it slow down as it won't get the trains loaded any faster... right?

Also, is that just during the initial "really fast" production, or also once the oil field slows down to a trickle?

You really only need 1 pipe unless the oil field is massive. A single pipe can support a maximum of 12000 fluid/sec, but loses flow rate with each tile away from a pump you get, but even after hundreds of tiles, you can still be over 1k fluid/sec, which is more than 30 pumpjacks that are each providing 30 oil/sec worth of throughput. Honestly, other than for unloading/loading fluid wagon, I find little use for pumps except to regulate fluid systems via circuit network (e.g. for cracking and perhaps coal liquefaction v adv. oil processing).

what i do to maximize oil flow is have 3-4 connect into a tank, then use a pump directly off the tank to pipe directly to a tank at the rail line. each 3-4 > tank > pump > tank connection is separated so that no back flow happens and there is no flow restrictions. only at the tanks at the station are there any cross connections between the tanks.
