The minimum spacing (and therefore the size of the plat) is based on hypothetical limits as to what can be drained by one well.  you'll need to look at the field rules to see what that is.  Location and formation would help a lot with your query.

Just curious,most plats I've seen has been around  600 acres +.I was told some outfit was going to do a 300 acre plat running north.Most of the directional drilling in this area/Tangipahoa  has been running north east.

                                    Thanks

A plat can be anything from the cosmos to wherever?

Wineshine, I think you may be saying "plat" when what you intend is "unit".  When we post and discuss a plat here on GHS, it is usually a plat of a drilling unit.  Is your question about the minimum size that a unit can be?

to follow up on Jay's comment, suppose that the requirement for the field is a minimum of 660' in all directions from the well bore.  On a vertical well, you could think of it as a square that is 1320' x 1320' or 40 acres.  

A horizontal well from that same point would start with the same minimum potential.  Every 1' of lateral length would add 1320 square feet to the size of the unit.  

So, suppose the lateral is 4000' long.  4000 X 1320 = 5280000/43560 = 121 acres + 40 acres or 161 acres total.  

The operator could drill a shorter lateral under lease rights, but its often most economical to drill longer.  And if they have more than a little holding in a section, they can potentially form a unit sized to the section or larger.
