Yang Jing put the thirteen famous paintings into the space and immediately felt at ease.

This independent space is safer than the safest safe in the world. The most important thing is that there is no dust or dirt in the space, no gravity, and no time seems to pass. Not to mention that the thirteen paintings can be kept for a long time, even if a cup of steaming coffee is put upside down into the space, the coffee will not flow out. Moreover, after being placed in the space for three days, the coffee is still steaming hot when it is taken out, and it has not deteriorated at all...

This kind of space, which is safe and can preserve its quality for a long time, is simply amazing and so lovable!

After having fun in this space for three days, Yang Jing once again focused his attention on the old oil well.

Twelve days had passed since the natural treasure gas was absorbed from this old oil well. According to Yang Jing's estimation at the time, the changes in the thick oil at the bottom of the well should be almost the same by now, so Yang Jing asked the workers to reopen the seal at the bottom of the well.

The changes observed at the bottom of the well this time will definitely not be the same as the last time. This old oil well has completely changed in the past ten days. Once the seal at the bottom of the well is opened, oil can be pumped out.

At this time, the oil pressure at the bottom of the well has reached 2.6 MPa. This pressure is not enough to make the well self-flowing, but once the seal at the bottom of the well is completely opened, it is equivalent to completing a new oil well and then shooting through the oil layer.

Under the pressure of the well, and the pumping of the oil pump, streams of sticky crude oil were quickly pumped up along the oil pipe. At a flange that Yang Jing had specifically instructed to be loosened, a little bit of the crude oil flowed out from the gap of the flange. Yang Jing put his finger on it, and the next moment, the situation at the bottom of the well appeared in Yang Jing's consciousness again.

In that huge oil bubble, the changes in the thick oil have not completely stopped, but the changes have been very slow. It is estimated that in another day or two, this magical change will completely stop.

What made Yang Jing happy was that about one-third of the heavy oil in the large oil bubble, which was originally full of heavy oil, had now turned into recoverable crude oil. Although it was not half of what was expected at the time, this one-third was still a lot. A rough estimate was that there were at least 8 million tons of recoverable crude oil.

Eight million tons is almost 60 million barrels, which is not a small amount for Rongbao Mining. For Yang Jing, a shareholder who holds 30% of the shares of this oil well, these eight million tons of recoverable crude oil are enough to bring him a pre-tax profit of at least one billion US dollars!

After Yang Jing was satisfied with the workers tightening the loose flange, he washed his hands and said to Guo Dabao, who was waiting impatiently, "Uncle Guo, go all out! According to my estimate, this oil well can produce about 60 million barrels of crude oil. Of course, you can also make an estimate. I think the number you get should not be much different from mine."

When he heard the number "60 million barrels", Guo Dabao immediately let out a long sigh, and a flush suddenly emerged on his dark face.

Before today's oil extraction, Zhao Meng had already told Guo Dabao the approximate extraction cost.

Although this old oil well is very old, once oil production is resumed, the cost of production is still very low.

Because of Yang Jing, the most expensive survey cost in oil field construction has been eliminated. With the old wellhead, the cost of re-expanding the well is not high. These two most expensive projects are not involved in this old oil well, which directly reduces a large part of the mining costs.

If we only take into account various expenses such as electricity costs, material loss, and labor, the cost of extracting crude oil from this old oil well is less than seven dollars per barrel!

Of course, if this well ultimately fails to produce any crude oil, or produces very little crude oil, then this old oil well will still lose money.

But now that Yang Jing mentioned the number of "60 million barrels", it was enough to make all of Guo Dabao's previous worries disappear.

According to the current crude oil price in the international crude oil futures market, this old oil well is enough to bring a huge amount of net profit to Rongbao Mining, even more than all of Guo Dabao's current wealth! Even if 30% of the shares were given to Yang Jing, the remaining amount would still be more than all of Guo Dabao's current wealth!

This old oil well is truly a treasure trove!
