Natural Gas Extraction and Transportation Overview

Natural Gas Extraction and Transportation Overview

Natural gas extraction and transportation is a critical part of ensuring that this clean energy source reaches the end user from the point of underground resources. Below is a basic overview of natural gas extraction and transportation:

natural gas extraction

Geological exploration and drilling:

- Geological exploration: Determining the location, reserves, quality and extraction conditions of natural gas deposits by means of geological surveys, geophysical exploration (e.g., seismic wave detection), and geochemical analyses, etc. Drilling: The drilling of wells in selected natural gas fields.

- Drilling: Drilling operations are carried out at the selected location of the natural gas field to penetrate the earth's crust and reach the gas-bearing layer. After drilling is completed, wellhead equipment, including blowout preventers and casing, is installed to ensure the safety of the well.

gas transportation

1,Gas gathering and processing:

- Gathering Station: Extracted natural gas is first transported to the gathering station, where it undergoes pre-treatment steps such as preliminary dewatering, desanding, and separation of condensate, in order to remove impurities and ensure pipeline transportation safety.

- Compression and Boosting: At the gathering station or at boosting stations along the route, the natural gas may need to be pressurized by a compressor to overcome friction losses and terrain elevation differences during long-distance transportation.

2,Main transportation methods:

Pipeline transportation:

- Natural gas pipeline: most natural gas is transported through a network of long-distance pipelines laid, including trunk lines, branch lines and urban distribution networks. Pipeline transportation has the advantages of strong continuity, large capacity and relatively low cost. It is a better way of gas service.

- Facilities along the pipeline: There are monitoring stations, pressure regulating stations, metering stations and other facilities along the pipeline, which are used for real-time monitoring of the operation status, regulating the pressure, metering the transportation volume and so on.

Liquefied natural gas (LNG) transportation:

- Liquefaction and Storage: For natural gas energy sources that are located far from consumer markets or need to be transported internationally across oceans, the natural gas is cooled to approximately -162°C at the liquefaction terminal, which reduces its volume dramatically (to approximately 1/600th of its original gaseous state), facilitating efficient transportation.

- LNG Carrier: The liquefied natural gas is loaded onto a dedicated LNG Carrier and transported across the ocean to the receiving terminal.

- Regasification and Distribution: Once at its destination, the LNG is regasified at the receiving terminal by heating or evaporation and then distributed to end-users or further injected into the local gas pipeline network via onshore pipelines or tankers.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
