The exploration work is carried out step by step.

The exploration methods during this period were relatively backward, the main reason was that computers had not yet developed in this era... Computers were still in their infancy, which is the "super secret" used for decoding in the UK, but this kind of primitive computer is definitely not used to assist in data analysis.

Otherwise, by using seismic exploration, that is, by manually detonating the explosives and receiving reflected waves from the ground, the structure of the underground rock formation can be analyzed and the inclination, anticline can be easily found and the wells are dug at the anticline.

The method used in this era is the most basic geological exploration method, that is, drilling wells at different depths to take samples, analyzing the components of the samples to collect data, and then drawing a geological profile diagram based on these data and thus determining the anticline position.

This process is simple, but requires a lot of work.

The hardship is that Qin Chuan knew that there was oil under his feet, but he watched this group of exploration work busy sampling, analyzing, and calculating on the surface...

But then again, these tasks are also necessary. Otherwise, it would be harder to find oil than climbing to the sky like a headless fly.

Qin Chuan was considering more confidentiality work at this time.

If you continue like this, you will definitely get oil... There is oil underground, and Professor Buckhouse is not a person who seeks fame. Moreover, even if Professor Buckhouse and others have no knowledge to mess around, the chance of finding oil underground is also very high. Unless Qin Chuan's modern memory is wrong.

Therefore, Qin Chuan believes that what he should consider more is what he has to do after finding oil.

Refining won't be a problem.

At this time, what Germany lacked the most was oil, and most of its oil had to be imported from Romania. However, even so, Germany's fuel was still insufficient to cover its expenses, which directly led to Germany having to refine oil from coal (Note: Coal refining is to decarbonize coal and hydrogenate coal. Germany had mastered this technology during World War II, but the cost was very high).

In this case, if we knew that Africa had found oil, Hitler would even use the national efforts to build an oil refinery and other related facilities here as quickly as possible.

It may even change Hitler's strategic focus... One of the reasons why Hitler attacked the Soviet Union was to seize the Baku oil field. If oil was found in Africa, the strategic significance of the Eastern Front would be weakened, and instead the importance of North Africa would rise sharply.

So, these are not something Qin Chuan needs to worry about.

What Qin Chuan has to worry about is how to keep this secret.

Use radar stations to provide cover for drilling like now?

Qin Chuan didn't think this could be hidden... It would be fine if the oil was not produced, but could it be hidden after the oil was produced? The transportation of oil and the construction of refineries will clearly tell the British the location of the oil field.

So Qin Chuan found Colonel Slein.

"Colin!" Qin Chuan said: "Have you ever thought... after we found the oil, we can no longer use the radar station to continue hiding it?"

Colonel Slain poured coffee for Qin Chuan and said, "Captain, is it too early for you to worry about this? We haven't even seen the shadow of oil yet! Maybe... oil is just a mirage to us!"

Mirages are not uncommon in the desert, especially in the area where the Gabes defense line has a salt lake.

"But I think we should be on guard against it before it happens!"

"How to prevent Yu Weiran?" Colonel Slain looked at Qin Chuan with an incredible look: "You mean... can we still hide it from the British after we find the oil? Please, it is not a secret at that time. Unless we don't use this discovered oil field, do you understand? Otherwise, people all over the world will know where it is!"

Colonel Slein's words were right, and this was the same as Qin Chuan thought: Once the oil field was put into use, the next line would be a long queue of trucks that would connect to Algiers, and then transport them from Algiers to France, Italy and Germany. The British did not even need spies. The air reconnaissance planes would look down and know that the end of the "long dragon" was the oil field.

Therefore, now using radar stations to disguise drilling and all confidentiality measures are only temporary, and the purpose is more to protect the exploration team. Another is not to let the British know that the African Legion is so short of oil that it needs to find oil on the spot... Otherwise, they are likely to launch a large-scale attack again.

But Qin Chuan was not talking about this.

"Colin!" Qin Chuan replied: "What I mean by confidentiality does not refer to the location of the oil field!"

"What will that be?" Colonel Slain looked at Qin Chuan in confusion.

"There is oil inland North Africa!" Qin Chuan replied.

"But you're not sure if it really exists!"

"What if I'm sure?" Qin Chuan said: "If you really dig oil, as we said before, when the British knew this, they would look for oil in Libya, Egypt inland, instead of along the coastline, and they would find much more oil than we do!"

Colonel Slain almost laughed out loud: "Please, Captain! You are the only one here who thinks that North Africa is full of oil! Even if we run to Montgomery to tell him... we dig oil in the desert, you can try it! Do you know what will happen? He, including all the British, would think this is a trap, or they just think we are crazy!"

Qin Chuan can understand Colonel Slein, which is a limitation of the times. Just like talking about taking off a plane with the primitive people, it will be denied.

But Qin Chuan had to insist, because this involved not only the British-German War, but also Japan and China.

Germany attacked the Soviet Union for oil. The mistake of this strategy stems from the fact that the Germans did not know that there was oil in North Africa, otherwise there would not be this war at all.

Similar to Germany, Japan attacked the United States for oil. The mistake of this strategy stems from Japan's lack of knowing that China has oil, otherwise there would be no US-Japan war or even the United States might not have participated in the war.

Simply put, Germany and Japan both sit on the treasure mountain but return empty-handed.

Ultimately, it is the misunderstanding of oil in this era, thinking that oil will only be near the coastline and focus on exploration in the coastal area.

What if Japan also realizes that there is oil in China and adjusts its exploration focus?

Qin Chuan couldn't even think about what happened next... Japan might discover the Daqing Oilfield, and then they would have the same situation as Germany and their strategic significance to the United States declined. They would devote themselves to building the Northeast, and then build Northeast China into a military machine like Algeria.

This is an irony. What Qin Chuan did to survive in North Africa seems to affect the motherland on the other side of the ocean.
