Rising Gas-Oil Ratios in Delaware Basin Oil Targets
Oil-targeted development in the Delaware Basin is increasingly challenged by rising gas–oil ratios, raising questions about fluid evolution and long-term oil yield across core benches.
Well Jumpin Jack Flash - who coulda knowd, a bubble point is reached where an oil well turns into a gas well.
It works like this. Initially, the gassy oil flows easily because the gas is dissolved in the oil under high pressure. But as the oil is pumped and the pressure drops, the gas begins to fizz out of the oil. Gas escaping from a freshly opened can of beer does the same thing. When a can is opened, pressure falls and the gas comes out. The same thing happens with gas dissolved in pressurized oil underground when pumping the oil reduces the pressure.
The oil is trapped within a rock matrix. Gas molecules move through the rock's pores much more easily than oil, flowing around the oil. As a result, the oil stops moving.
So, we may have finally reached peak bullshit.
Water, water, every where,
Nor any drop to drink.
