I believe I read anything above 25bbl
However, I also recall that was from a poster. I try to keep my coffee clean.
That said, sensibly, the cost of implementation will/can vary significantly based on the wells location, drilling costs (if needed) accessibility etc.
Meaning there can't be a flat rate per well, or field.
I'm not O&G but common sense tells me this.
Make sense??
