v3 Chapter 928： Class D oil field (1/2)

With the continuous and in-depth development of science in later generations, there are various methods of petroleum exploration, including seismic exploration, gravity exploration, magnetic exploration, electrical exploration, geochemical exploration and so on.

In each category, more detailed methods have been subdivided through precise research by scientific researchers.

After all, oil is stored in a special stratigraphic structure. It is not easy to find it, and it requires very precise exploration.

From another perspective, after hundreds of years of development, in the face of black gold oil, the most surface oil that is easy to explore has long been found out by carpet search. What has not been discovered is the hard bones that are hidden deeper. The underground is also more concealed, and you must rely on sophisticated methods to find it out.

Moreover, in order to obtain more precise results and improve accuracy, several methods are used together.

However, this time of exploration is based on the use of the three-dimensional seismic exploration technology that just appeared in the 1970s and has been further developed in the two-dimensional seismic exploration technology. The comprehensive application technology integrating physics, mathematics and computer science can make underground targets The image is clearer and the position prediction is more reliable.

Even in later generations, three-dimensional seismic exploration is one of the most important methods in geophysical exploration, and it is the world's main exploration technology for underground natural minerals such as oil, natural gas, and coal.

Just when the old Jack and the others began to drill a small well to prepare to fill the explosives, Xia Yu walked to Bush Jr. and asked, ”Mr. Bush, who shouldn't rent or buy this land yet?”

George W. Bush shook his head and said, ”No, there are signs for sworn sovereignty on land that has a master. We didn't see it when we came.”

The old Jack who was digging a well also heard the conversation between the two and immediately replied: ”Chairman, I went to the town's Land Management Bureau the day before yesterday. This large area is blank and no one has rented it yet.”

Xia Yu nodded slightly and said to Bush: “There must be oil here. Although we can lease the land after detecting the results, there is still a risk of exposure. It is difficult to guarantee that it will not be discovered by a passing exploration team. Rent this land.”

”What's more, there are a lot of blasting wells to be dug now. It will take some time. It is better to go back and let other employees come together and rent this land by the way.”

Xia Yu's so swearing promise and the concerns raised really affected Bush.

He glanced at the busy old Jack and others, and nodded in agreement with Xia Yu's opinion.

After instructing the old Jack and others to continue their work, Bush Jr., Xia Yu and others got in the car again, went straight on to the nearest highway, and then galloped along the highway.

The United States is vast and sparsely populated, and the barren land in the wild is not valuable, even in the oil-rich Texas.

For more than a hundred years, the cities and towns of Midland have already perfected all aspects of oil extraction, which naturally includes the initial land lease and sale. Every year, the local government will announce the standards for land lease and sale in different locations. The price and the price level are related to whether there are oil fields nearby. Naturally, the price of idle land near large oil fields will be higher than ordinary wasteland, but there are certain limits.

The price difference between buying land and renting land is relatively large.

Moreover, once oil is discovered, it can be exploited within a few years, and the slower one is only about ten years. Unless it is a super large oil field, it takes decades to be exploited, but such super large oil fields are rare. One is enough to make a sensation in the world!

Therefore, it is generally sufficient to rent land for ten years, and according to the contract, you have the right to continue to renew the contract. There are also restrictions on the fluctuation of the rent. It can be said that all aspects have been taken into account, making people feel relieved and boldly explore (bet) oil. .

The land Xia Yu and others wanted to rent had been rented by at least ten people in the previous hundreds of years, but because of technical problems or other reasons, no oil was discovered before, and now the land has returned to the local government.

It was about 1 in the afternoon, and that large piece of land was rented by Bush Energy Company for ten years at a price of nine thousand dollars a year, and it obtained all the legal rights to the land, including mineral exploration, mining and ownership.

Around two o'clock in the afternoon, all sixteen small wells were dug and explosives were filled at the bottom of the well. The geophone and the instrument cart were connected by cables.

”Chairman, the preparations are done!”

”Then start testing!”

After finishing talking, Xia Yu, Bush Jr. and others went a little farther, one is to be safer, and the other is to avoid interference with seismic signal acquisition.

I saw Old Jack start the device, and after a while I heard a series of dull explosions.

The transmission speed of sound waves is very fast. After waiting for more than two minutes, Xia Yu and others hurried to the instrument car.

The instrument cart is equipped with a special electronic computer, which will process and calculate the data transmitted from the detector through the cable according to the set program. The data will be classified and arranged to highlight the valid and remove the invalid and interference data. Finally The technicians superimpose and migrate the processed data, and finally obtain a seismic section or 3D data volume file.

A group of people gathered around the technician, watching him continuously operate a special electronic computer. About twenty minutes later, a seismic profile map came out.

Then Jonathan, another staff member wearing glasses, stepped forward and analyzed the seismic profile.

Bush and others all subconsciously let go of their breaths, their eyes fixed on the profile.

Whether there is oil or not depends on the analysis result of the seismic profile.

Time comes over every minute.

Jonathan has been frowning and analyzing the data.

Suddenly, his brows trembled, and he leaned forward to look at the lower right corner of the profile.

”Jonathan, did you find it?”

Bush Jr. asked hurriedly, feeling a little uneasy.

Jonathan pointed to the section in the lower right corner, feeling a little excited and replied: ”Chairman, this piece of stratum structure is different, and according to the analysis of the seismic wave reflection results, it is very similar to the oil and gas trap structure, where it is possible to store oil!”

Hearing this, everyone showed excitement.

Bush immediately said: ”Quickly calculate the position and re-explore!”

Except for Xia Yu and Li Wuming, everyone immediately got busy.
