Define Total Petroleum Initially-in-Place.

Why is the equation for Oil Initially-in-Place is divided by Formation Volume Factor?

• Because oil expands at surface conditions

• Because oil shrinks at surface conditions

• Because oil shrinks at subsurface conditions

Why is the equation for Gas Initially-in-Place is multiplied by Formation Volume Factor?

• Because gas expands at surface conditions

• Because gas shrinks at surface conditions

• Because gas expands at subsurface conditions
