: 413 Petroleum Exploration

At this time, a resource exploration ship was moored on the sea.
Chen Rui's yacht was next to the resource exploration ship and boarded the exploration ship by a small boat.
On the exploration ship, dozens of oil prospectors were busy nervously.
These petroleum exploration personnel include geological engineers, reservoir engineers, geophysical data collection, interpretation, processing engineers, numerical simulation, logging, supervision positions, and so on.
They belong to Halliburton Energy Services.
Halliburton is currently the world's largest oil and energy industry service company. The company's main job is to provide equipment and services for oil and gas exploration, development and drilling, and infrastructure construction.
They have been working on Tortuga Island for more than half a year.
They are employed by the Royal Asset Management Committee of Tortuga Island. Their main job is to explore more than 180 square kilometers of land on Tortuga Island, tens of thousands of square kilometers of territorial waters, and oil and gas resources in the exclusive economic zone.
Anyone who has learned about geology and petroleum exploration knows it.
To form natural oil, three conditions are required.
1. Sedimentary rocks suitable for petroleum generation. Sedimentary rocks are formed over millions of years. The sediments contain fish, shell aquatic animals, plankton, plants, etc. These organic substances decompose due to heat or age. Into oil and gas.
2. Porous rocks that store petroleum. Porosity will be filled with petroleum like a sponge.
3. Impervious rocks ‘cover’ the oil and seal it up.
Oil prospectors look for these three rocks.
"Hey, Bill, is everything going well at work?" Chen Rui walked into a studio, one wearing a blue plaid shirt and jeans, and was slightly fat. Wearing black-framed glasses, the old man, about 5 or 60 years old, sat in front of the computer, staring intently at the computer screen. With a pen in his hand and a notebook on the table. The notebook was full of dense data, sketches.
The old man was Bill Bob, an internationally renowned geological engineer who served as the captain of the petroleum exploration team here.
Previously, in order to learn more about the work progress of the oil exploration team, Chen Rui had been here. Bill Bob also invited Chen Rui to have a lunch on board, and the two were very familiar.
"It worked very well." Bill Bob sat at the computer. Hearing Chen Rui asking, looked up and said to Chen Rui with a smile.
The main processes of petroleum exploration and development are: geological prospecting-geophysical prospecting-drilling-logging-logging-completion-cementing-perforation-oil production-workover, incremental production and subsequent transportation And processing.
At the beginning of the year, Bill Bob led an oil exploration team to the island of Tortuga. First of all, he used professional geological knowledge to directly observe and study the ground floor and rocks on the ground, and collected rock formations on the sea floor to understand the sedimentary strata And structural characteristics to collect all geological data in order to find out favorable zones and distribution laws of oil and gas generation and accumulation. To achieve the goal of finding oil and gas fields.
This is the 'census' of the geological survey method.
Then, a 'scrutiny' was carried out in the 'selection', and its promising areas of the 'census' further confirmed the selection of more powerful oil-bearing structures.
The final step is ‘fine measurement’. It is mainly reflected in the "setting", the target of the "detailed investigation" is to specifically determine the oil-bearing structure, and to prepare an accurate structural map for further drilling.
This is the survey and geophysical process.
These two processes took more than six months for the exploration team.
Finally, the 'detailed search' target, that is to say, the place where Tortuga Island and the exclusive economic zone are most likely to have oil is located in this sea area, 40 nautical miles northwest of Tortuga Island, in Tortoga Altuga Exclusive Economic Zone.
"Where has the exploration now proceeded?" Chen Rui poured himself a glass of boiling water, took a light sip, and looked at Bill Bob. Said Bill Bob.
"The survey is over, and the work of geophysical exploration is coming to an end," said Bill Bob. "The data returned by magnetic measurement, gravity measurement and other methods. It is very likely that there is an oil and gas field under the ocean floor through computer analysis."
Magnetic measurement method, gravity measurement method, I used to know something when talking to Bill Bob. All rocks are magnetic, but there are slight differences in the magnetic properties of various rocks. Based on this, you can know the structure and type of underground rocks, and the root magnetism. The barometer can measure changes in magnetic data and draw a stratigraphic structure map.
The gravity measurement method is based on the density difference between the detected object and the surrounding rocks (mines), ....
"Congratulations, you have done very successfully." Wen Yan said with a smile, "Congratulations, you have done very successfully."
"Mr. Chen, I should congratulate you, this is your oilfield." Bill Bob said with a smile.
"When can we drill?" Chen Rui asked.
"We calculated the position of the rock formations using magnetic measurement methods and seismic exploration methods, and we also produced a stratum structure map and a detailed cross-section view of the formation. After the drilling equipment arrives from the United States, we can drill for about half a month. Then, "said Bill Bob.
Chen Rui nodded.
Halliburton Energy Services is one of the world's largest suppliers of energy products and services, from oil and gas exploration, development, production, operation, maintenance, conversion and refining, to infrastructure construction and even the abandonment of oil and gas fields. To provide products and services along the entire oil and gas chain.
The petroleum exploration and drilling service contract signed by the Royal Assets Management Committee and Halliburton Energy Service Department ~ EbookFREE.me ~ service fee is more than 10 million US dollars.
After the successful drilling of oil, there are contracts for the construction of offshore oil extraction platforms, the construction of oil refineries, and the construction of oil pipelines. These contract service fees may exceed US $ 1 billion.
The reason why the Royal Assets Management Committee thought of hiring Halliburton's oil prospectors to explore the oil and gas resources on the territory of Tortuga Island, the territorial sea, and the 200-mile exclusive economic zone.
This is what Chen Rui intended.
The Kingdom of Tortuga has just been established. Chen Rui entrusted the Royal Assets Management Committee to hire professional oil exploration personnel to explore the oil and gas resources of Tortuga Island.
Chen Rui's thoughts seemed very reasonable and normal to others.
Although the area of ​​Tortuga Island is very small, only more than 180 square kilometers, with little resources, but the territorial sea, contiguous area and exclusive economic zone of Tortuga Island are not small.
Extending a range of 200 nautical miles from the sea baseline, adding up to tens of thousands of square kilometers, the possibility of possessing oil and gas resources is very large. (To be continued)
