The Moveable Oil Plot
Sxo = [ (a / Fm)*(Rmf / Rxo) ](1/n)
- Rmf: Resistivity of mud filtrate
- Rxo: Microresistivity
- presumably bulk resistivity of flushed zone
- Sxo: Saturation of total moveable fluid
- assumes filtrate has displaced everything moveable
BVF = Sxo*F
- Bulk volume (moveable) fluid
Volume moveable oil = BVF - BVW
