Exploration work proceeded in a step-by-step manner.

The exploration methods of this period were relatively backward, mainly because computers had not yet developed in this era...... At this time, computers were still in their infancy, that is, the "super secret" used for decoding in the United Kingdom, but this primitive computer certainly could not be used to assist in the analysis of data.

Otherwise, by using the seismic exploration method, that is, artificially detonating the explosive charge and receiving the reflected waves from the ground, the structure of the underground rock formation can be analyzed and the anticline and anticline can be easily identified and the anticline can be drilled.

The method used in this era is the most basic geological exploration method, that is, drilling wells at different depths, taking samples, analyzing the composition of the samples, collecting data, and then drawing geological profiles based on these data to determine the location of the anticline.

It's a simple process, but it takes a lot of work.

Qin Chuan obviously 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 jobs are also necessary, otherwise it will be more difficult to find oil like a headless fly.

Qin Chuan was thinking more about secrecy at this time.

It's a sure thing that oil will go on like this...... There is oil in the ground, and Professor Buckhouse is not a person who sells his reputation, not to mention that even if Professor Buckhouse and others have no knowledge to mess around, the probability of finding oil in the ground is very large. Unless Qin Chuan's modern memory is wrong.

Therefore, Qin Chuan thinks that he should think more about what happens after he finds oil.

Oil refining won't be a problem.

At this time, Germany was most lacking in oil, most of its oil had to be imported from Romania, but even so, Germany's fuel still could not make ends meet, which directly led to Germany having to refine oil from coal (note: coal refining is to decarbonize coal and hydrogenate, Germany has mastered this technology during World War II, but the cost is very high).

Under these circumstances, if he had known that oil had been found in Africa, Hitler would have even spared no expense in building an oil refinery and other related facilities here as quickly as possible with the strength of the whole country.

It may even change Hitler's strategic focus as a result...... One of the reasons for Hitler's attack on the Soviet Union was to seize the Baku oil fields, and if oil was found in Africa, the strategic significance of the Eastern Front would be weakened, and the importance of North Africa would skyrocket.

Therefore, these are not things that Qin Chuan needs to worry about.

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

Cover for drilling with radar stations like now?

Qin Chuan didn't think that this could hide anything...... It's good that the oil didn't come out, but can you hide it after the oil is out? The transportation of oil and the construction of oil refineries will clearly tell the British the location of the oil fields.

So Qin Chuan found Colonel Slain.

"Colonel!" Qin Chuan said, "Have you ever thought about it...... After finding the oil, we can't use the radar station to continue to hide it? ”

Colonel Slane casually poured coffee for Qin Chuan and said, "Captain, are you a little worried about it too early?" We haven't even seen the shadow of oil yet! Maybe...... Oil is just a mirage for us! ”

Mirages are not uncommon in the desert, especially in areas where the Gabes Line has salt lakes.

"But I think we should be on guard!"

"How can we prevent it from happening?" Colonel Slane looked at Qin Chuan with an incredible look: "You mean...... Can we hide it from the British after we find the oil? Please, it won't be a secret then, unless we don't use this discovered oil field, understand? Otherwise the whole world would know where it is! ”

Colonel Slein was right, and this was the same as what Qin Chuan thought: once this oil field was put into use, the next step would be a long queue of trucks all the way to Algiers, and then from Algiers to France, Italy, and then to Germany.

So, the use of radar stations to camouflage drilling and all the secrecy measures is now only temporary, and its purpose is more to protect the exploration team, and the other is not to let the British know that the Afrika Korps is short of oil to the point that it needs to be found on the spot...... Otherwise, there is a high probability that they will launch another large-scale offensive.

But what Qin Chuan said was not this.

"Colonel!" Qin Chuan replied: "When I say secrecy, I don't mean the location of the oil field!" ”

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

"There's oil in the interior of North Africa!" Qin Chuan replied.

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

"What if it's for sure?" Qin Chuan said: "If oil is really dug up, like we said before, after the British know this, they will look for oil in the interior of Libya, Egypt instead of along the coastline, and they will find much more oil than us!" ”

Colonel Slain almost burst out laughing, "Please, Captain! Here is the only one you would think that North Africa is full of oil! Even if we run up to Montgomery and tell him...... We've dug up oil in the desert, so you can try it too! Any idea what to expect? He, including all the Britons, would have thought it was a trap, or they thought we were crazy! ”

Qin Chuan can understand Colonel Slain, this is a limitation of the times, just like talking to primitive people about airplanes will be denied.

But Qin Chuan had to insist, because it involved not only the Anglo-German war, but also Japan and China.

Germany attacked the Soviet Union for oil, and the mistake of this strategy stemmed from the fact that the Germans did not know that there was oil in North Africa, otherwise there would have been no war at all.

Similar to Germany, Japan's attack on the United States was also for oil, and the mistake of this strategy stemmed from the fact that Japan did not know that China had oil, otherwise there would not have been a war between the United States and Japan, and the United States might not have even entered the war.

To put it simply, Germany and Japan are sitting on the treasure mountain and returning empty-handed.

In the final analysis, it is the era that has led to the misconception that oil will only be explored near the coastline and mainly along the coast.

What if Japan also recognized that there was oil in Chinese mainland and adjusted its exploration priorities?

Qin Chuan couldn't even think about what happened next...... Japan may discover the Daqing oil field, and then they will be in the same situation as Germany, and their strategic significance to the United States will decrease, and they will devote themselves to building Northeast China, and then they will build Northeast China into a military machine like Algeria.

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

Qin Chuan must not let such a thing happen!
