>Hello Sohib EditorOnline, welcome to this journal article about minyak bumi diperoleh dengan cara. Minyak bumi is a valuable natural resource that is widely used in various industries. In this article, we will discuss how minyak bumi is obtained from the earth and the various methods used for extraction. So, let’s dive in and explore together!
1. Introduction to Minyak Bumi
Minyak bumi or petroleum is a dark liquid that is found beneath the earth’s surface. It is formed from the remains of dead plants and animals that lived millions of years ago. Over time, the organic matter was buried under layers of sediment and subjected to heat and pressure, which transformed it into minyak bumi.
Minyak bumi is a complex mixture of hydrocarbons, which are compounds made up of hydrogen and carbon atoms. The properties of minyak bumi vary depending on the composition of the hydrocarbons present in it. Some of the common properties of minyak bumi are its density, viscosity, and boiling point.
2. Exploration for Minyak Bumi
The first step in obtaining minyak bumi is to explore for its presence beneath the earth’s surface. This involves conducting geological and geophysical surveys to identify potential locations where minyak bumi may be present.
One of the most common methods used in the exploration for minyak bumi is seismic surveying. This involves creating shock waves on the earth’s surface and measuring the vibrations that are reflected back to the surface. By analyzing the data obtained from these measurements, geologists and geophysicists can identify the presence of minyak bumi reservoirs.
2.1 Seismic Surveying Process
The seismic surveying process starts with the placement of explosive charges in shallow holes drilled into the ground. These charges are detonated, creating shock waves that travel through the earth’s surface and penetrate the underlying rock formations.
The reflected vibrations are recorded by sensors called geophones, which are placed at various locations on the surface. The data obtained from these recordings is then processed using specialized software to create a three-dimensional image of the subsurface.
This image allows geologists and geophysicists to identify the location, size, and shape of minyak bumi reservoirs, as well as potential drilling sites.
2.2 Other Methods of Exploration
Other methods used in the exploration for minyak bumi include gravity and magnetic surveys, as well as surface mapping and drilling. These methods are used in conjunction with seismic surveying to obtain a more accurate picture of the subsurface geology and the presence of minyak bumi.
3. Drilling for Minyak Bumi
Once a potential minyak bumi reservoir has been identified, the next step is to drill a well to extract the minyak bumi. The drilling process involves creating a hole in the earth’s surface and penetrating the rock formations until the minyak bumi reservoir is reached.
The drilling process is complex and requires specialized equipment and expertise. There are several types of drilling techniques used for extracting minyak bumi, including onshore drilling, offshore drilling, and directional drilling.
3.1 Onshore Drilling
Onshore drilling is the most common type of drilling technique used for extracting minyak bumi. It involves drilling a well directly into the earth’s surface from a land-based location. The drilling rig is typically mounted on a platform and is supported by a network of cables and towers.
The well is drilled vertically until the minyak bumi reservoir is reached. Once the reservoir is reached, the drilling process may be modified to extract the minyak bumi more efficiently, such as through horizontal drilling.
3.2 Offshore Drilling
Offshore drilling is used to extract minyak bumi from beneath the ocean floor. It typically involves drilling from a specially designed platform, known as a drilling rig, which is located in shallow or deep waters.
Offshore drilling is more complex than onshore drilling and requires specialized equipment and expertise. It is also subject to greater environmental and safety risks, such as oil spills and accidents that may harm marine life and the local ecosystem.
3.3 Directional Drilling
Directional drilling is a technique used in both onshore and offshore drilling to extract minyak bumi more efficiently. It involves drilling the well at an angle, rather than straight down, in order to reach areas that cannot be accessed by vertical drilling.
Directional drilling is particularly useful for extracting minyak bumi from offshore reserves or reserves situated beneath urban areas or sensitive ecosystems.
4. Minyak Bumi Extraction Process
Once the well has been drilled and the minyak bumi reservoir has been reached, the extraction process can begin. The extraction process involves pumping the minyak bumi to the surface, where it is processed and refined into usable products.
There are several methods used for extracting minyak bumi, including primary recovery, secondary recovery, and enhanced oil recovery.
4.1 Primary recovery
Primary recovery is the initial extraction of minyak bumi that occurs naturally due to the pressure of the reservoir. This process involves pumping the minyak bumi to the surface using a pump, where it is stored and transported to refineries for further processing.
4.2 Secondary recovery
Secondary recovery is used when the pressure in the minyak bumi reservoir declines, and the primary recovery methods are no longer sufficient to extract the minyak bumi. This process involves injecting water or gas into the reservoir to increase the pressure and force the minyak bumi to the surface.
4.3 Enhanced oil recovery
Enhanced oil recovery is a more advanced method of minyak bumi extraction that utilizes various techniques to increase the amount of minyak bumi that can be extracted from the reservoir. These techniques include thermal recovery, chemical recovery, and microbial recovery methods.
5. Minyak Bumi Processing and Refining
Once the minyak bumi has been extracted, it is transported to refineries for processing and refining. The processing and refining process involves separating the various components of the minyak bumi mixture into usable products, such as gasoline, diesel, and jet fuel.
The refining process involves several steps, including distillation, cracking, and reforming. These processes are used to extract the various hydrocarbons present in minyak bumi and convert them into usable products.
5.1 Distillation
Distillation is a process used to separate the various components of the minyak bumi mixture by boiling point. The minyak bumi is heated in a distillation tower, causing the various hydrocarbons to vaporize at different temperatures.
The vapors are then collected and condensed into different fractions, such as gasoline, diesel, and jet fuel.
5.2 Cracking
Cracking is a process used to break down larger hydrocarbon molecules into smaller, more usable molecules. This process involves heating the minyak bumi to high temperatures and pressures, causing the larger molecules to break apart.
The smaller molecules are then collected and further refined into usable products.
5.3 Reforming
Reforming is a process used to convert low-quality hydrocarbons into higher-quality hydrocarbons. This process involves adding hydrogen to the hydrocarbons and heating them to high temperatures and pressures, causing them to recombine in a more desirable form.
The resulting higher-quality hydrocarbons are then used to produce gasoline and other high-value products.
