How does this work?

It's a new well in the Zhuangxi Buried Hill Oilfield that already has a water cut of 34%. That's what i understand

How does what work? If you mean how can a new well have a 34% water cut, that's not at all uncommon. Remember that generally oil reservoirs were saturated with salt water before the oil migrated in, and every oil reservoir has some amount of water saturation. Depending on the exact pore geometry in the reservoir, a new well may or may not have a water cut. Typically, the oil occupies the larger pore spaces, while water occupies the smaller ones and also coats the surfaces of all of the grains of rock surrounding the pores (because of surface tension). In a pressure-depletion type of reservoir, as pressures decline, the water cut increases as it becomes easier for the water to escape from the smaller pore spaces.
