1
The oil and gas value chain is broadly divided into two segments.
2
Upstream for the discovery and production of crude oil and natural gas, and downstream for refinement and sales of the end products.
3
Each is a big industry of its own.
4
Due to the complexity of each segment, most companies focus on one, though major oil and gas companies are fully integrated across the value chain.
5
Let's start with upstream.
6
The world has a surface area of 200 million square miles.
7
How can oil companies know where oil and gas reserves are?
8
It starts with the exploration phase.
9
Explorations can be onshore or offshore, and the objective here is not to find oil or gas,
10
but to narrow down the search area by identifying potential reservoirs that might host oil and gas.
11
Have you ever seen someone selecting a watermelon by tapping on it
12
and listening for a hollow sound sound to see how ripe it is, oil and gas exploration process is similar to that, just more expensive.
13
A lot more expensive.
14
The exploratory process starts with seismic surveys of basins to scan below the surface and identify potential reservoir targets.
15
Seismic surveys use sound waves, akin to the watermelon tapping and listening method, to create images of subsurface rock layers.
16
The sound waves, generated by a loud bang, like the detonation of dynamite in a hole dug in the ground or from an air gun in the water,
17
travel through the Earth and are partially reflected by each rock boundary back to the surface.
18
Geophones placed at the surface record the reflections,
19
which are then digitized and analyzed by geophysicists to identify potential rock formations that could lead to oil and gas accumulations.
20
In addition to seismic surveys, companies also conduct regional studies to see if there are discovered reserves in neighboring countries with similar geographies.
21
This would increase the probability of discovering reserves in the basin under exploration.
22
Based on the results of seismic surveys and regional studies, companies will decide to proceed to drilling exploratory wells, which are typically 5 inches wide,
23
with a depth ranging from a few hundred feet to 20,000 feet.
24
Next, samples are collected from the drilled wells and tested, in attempts to confirm the presence of a reservoir and its properties in terms of volume and mobility,
25
that is, how easily the reservoir will flow.
26
Tests are used to create 3D models of the reservoir and to identify the depth of different layers of gas, oil, and water.
27
This is an important step because drilling to extract oil and gas is a delicate operation, and mistakes can be economically catastrophic.
28
Even with the most advanced tests and models, exploration is always a risky bet.
29
companies can spend millions drilling to find an empty well or wells that are not commercially recoverable with existing technologies.
30
With modern seismic survey technologies the chances of finding oil or gas is less than 20 percent.

本課的詞彙與口語要點
這節 C1 級別的口語課以影片“Inside the Upstream Process: How Oil & Gas Is Found”為素材。 影片中反覆出現的詞有：oil, gas, companies, seismic, reservoir。 這段影片共有 30 個句子、487 個單詞可供跟讀。 講話部分時長為 2:57。 說話人語速自然，每分鐘約 165 個詞，接近日常對話。 只有 77% 的單詞屬於英語最常用的 3,000 詞，詞彙難度較高。
影片中的重點詞彙
影片中最難的 15 個單詞，附發音和釋義：
| 單詞 | 發音 | 釋義 |
|---|---|---|
| seismic 形容詞 | /ˈsaɪzmɪk/ | 地震的 |
| reservoir 名詞 | /ˈɹɛz.ə(ɹ).vwɑɹ/ | 儲備 /儲備 |
| drill 名詞 | /dɹɪl/ | 鑽 /鑽 |
| upstream 形容詞 | /ʌpˈstɹiːm/ | 上游 |
| basin 名詞 | /ˈbeɪsɪn/ | 洗滌槽 /洗滌槽 |
| detonation 名詞 | /dɛtəˈneɪʃən/ | 爆炸 |
| digitize 動詞 | /ˈdɪd͡ʒɪtaɪz/ | 數字化 /數字化 |
| geophysicist 名詞 | 地球物理學家 /地球物理學家 | |
| catastrophic 形容詞 | /ˌkætəˈstɹɑfɪk/ | 災難的 /災難的, 災難性的 /災難性的 |
| dynamite 名詞 | /ˈdaɪ.nəˌmaɪt/ | 炸藥 /炸藥 |
| accumulation 名詞 | /əˌkjuːm.jəˈleɪ.ʃən/ | 積累, 累計 |
| ripe 形容詞 | /ɹaɪp/ | 成熟, 熟 |

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
