Topic > Conventional and Unconventional Systems in Petroleum Geology

IndexIntroductionMain AssessmentConclusionIntroductionA system is defined as a set of interacting parts that are made to function as a whole unit. The systemic view involves a methodical study of the connection between the component parts and how each of them works together (Christiansen and Hamblin, 2014). It has helped geologists, engineers, and researchers better understand how the Earth works and how each thing relates to each other (Christiansen and Hamblin, 2014). Most systems are open, that is, they can exchange matter and energy across their boundaries and share it throughout the area. These types of systems are often considered dynamic in nature as they generally have no boundaries within them. Naturally occurring systems, however, have a predefined boundary present in them. The boundaries of these systems may be covered by flowing water or covered by rocks, or the boundaries are considered arbitrary in nature as they are defined for research purposes. Everything outside the system is considered its surroundings and these are not considered part of the system (Christiansen and Hamblin, 2014). Systems are considered an integral part of science as they include all components of the Earth such as air, fire, water, and rocks, which allows engineers and geologists to gain a more complete understanding of the world (Butz, 2008).Say no to plagiarism .

The purpose of this evaluation is to explain and evaluate the differences found between the conventional system and the non-conventional systems. It would allow us to understand what can be obtained from them compared to the hydrocarbon resources that are collected from them. Furthermore, examples will also be provided to clearly illustrate the differences present in the two systems as well as the hydrocarbon resources also found from them. This would help to understand what kind of gases and oils can be produced from them and which can be used as fuel or oil.Main AssessmentConventional and unconventional hydrocarbon resources are generally formed during the thermal progression of rocks or fossils. Both are generally used to mean a certain amount of fuels that can be used to contribute to a reserve if the resources are extracted economically. The difference found, however, between them is that they both represent a different set of resources that can be removed, as well as the ease with which fuels can be obtained from them. Conventional resources such as oil and gas are obtained from traditional materials. resources are generally formed using standard or simple methods to extract products from them (Everett et al., 2012). Extracting fossil fuels from these is generally done using standard processes used to remove them from deposits. In general, conventional resources are considered more convenient and less expensive to produce as they do not require specialized technologies to extract them and accepted methods can be exploited to harvest them (Everett et al., 2012). Due to the simplicity it possesses and how convenient it is to produce one, it can be seen that conventional resources are generally some of the first resources used in industry activities. Furthermore, conventional oils are hydrogen-containing compounds that are made up of short hydrocarbon chains and hydrogen and carbon atoms ranging from C1 to C60. Because of this, you can see that these have weightslower molecular weight than unconventional oils (Gordon, 2012). Since most of the energy from these comes from hydrogen while carbon is only there to carry the hydrogen atoms, it can be seen that conventional oils produce more energy with less waste than their unconventional counterparts. In contrast, unconventional oils are considered harder to extract as some resources are seen to be trapped in reservoirs surrounded by reduced permeability and porosity. This leads to an increase in difficulty, or it is generally impossible for oil or gas to flow through the pores and exit into standard wells. Specialized techniques and tools are typically used to extract these resources and can be expensive to produce. To extract oils such as shale oil, a hydraulic fracturing step is used to form several cracks in the resources so that oil and gas can flow through them. In the case of oil sands, an in situ repository would use steam-assisted gravity drainage capable of forming thick bitumen from underground deposits. All these methods are considered expensive compared to the methods generally used for the extraction of conventional oils (Everett et al., 2012). However, these can be seen to allow the production of hydrocarbon products from places that were previously not accessible or from which it was not possible to extract them. These resources can generally be transformed into reserves which could then be used economically. These types of resources are generally identified by their distinct characteristics. The heavier the oil, the more carbon it contains, as well as being rich in sulfur and full of impurities. These are generally heavier than conventional oils (Gordon, 2012). Due to the contaminants found within it, impure oils typically require a significant amount of energy to be improved and transformed into synthetic crude oil that could then be used to produce petroleum-based products or fuels ( Gordon, 2012). Generally, it can be seen that some of the new oils are in solid form and need to be extracted by mining or heating until they are able to flow (Gordon, 2012). These new forms of fats are generally considered less valuable than traditional or conventional oils as they take longer to process and produce, which also makes them less marketable. Unconventional systems have generally played an essential role in the growing demand in global oil and gas production, demonstrated by the creation of oil sands, coalbed methane (CBM) and gas, along with the rapid increase in shale gas and tight oil production present in countries like the United States. (Jia, 2017). Furthermore, Venezuela and Canada are two of the main oil sands and heavy oil producing countries. These are generally more used as oil for decades, and natural gas productions have led to extensive use of conventional resources. For this reason, new technologies are being developed that could allow the extraction of unconventional oils through the use of economic methods previously thought impossible. The formation of these has significant commercial potential as a large part of the hydrocarbon reserves are estimated to be located in unconventional resources. Meanwhile, the largest production areas of conventional oils are the Middle East and Central Asia-Russia (Zou et al., 2014). Approximately two-thirds of the remaining recoverable reserves and undiscovered recoverable resources of conventional hydrocarbons are found primarily in these two regions, with oil and gas accounting for.
