=== Refinery placement ===
[[File:UCS best mining.png|thumb|The most efficient refinery placement against the resource field.]]
Usually it is best to place just 2 refineries (although there are scenarios, where placing 3 refineries is a valid option - you should take into consideration the fact that it costs more money to set up such facility, as this means that you will most likely want more harvesters as well). Refineries that are spaced 2 tiles away from the resource field perform better than refineries placed just 1 square (as most players do) from the resource field. The reason for the latter underperforming is, that sometimes (especially with more harvesters around), the refinery pickup spot can be just next to a mining dot (sometimes even 3 dots). If the refinery is currently occupied by harvester, then any of the harvesters that are mining just next to the refinery pickup spot will stay on the "dot" and wait till the refinery pickup spot gets free. In the variant with 2 tiles spacing, they move by 1 square towards the refinery, freeing the mining dot for other harvesters. It doesn't make any difference whether you place refineries on the opposite sides of the resource field, or both on the same side. Since it is better to have the buildings more grouped (to ensure more reliable energy coverage and to make the defense easier against rushing LC), it could be slightly better to place them on the same side if possible.
