Abstract
Hydrocarbon reserves estimation is important in the petroleum industry because it is the basis for which many decisions are made. There are several methods traditionally used to estimate reserves but in 1995 Mattar and McNeil introduced a new procedure called the Flowing Gas Material Balance (FGMB). The FGMB is considered a convenient method because it uses data that is already obtained and quantifies the gas in place without having to shut-in the well and interrupt production. This paper proposes to apply the Flowing Gas Material Balance method for reserves estimation to gas fields in Trinidad and Tobago and make a comparison with traditional methods of reserves estimation to confirm the efficiency of its application. To do this,

In 1993, Desorcy et al suggested that the poor economic climate and lower quality of reservoirs that were being discovered at the time necessitated the implementation of a universal set of definitions that could be used throughout the industry. In response to this need, in March 1997, the Society of Petroleum Engineers (SPE) and the World Petroleum Congresses (WPC) approved a list of petroleum reserves definitions to improve the level of consistency in estimating and reporting on a worldwide basis. In 2005, the SPE’s Oil and Gas Reserves Committee (OGRC) published a comparison of the various definitions (Etherington, Zuccolo, and Spe 2005). Advancements in technology and expansions in the exploration and production sector made it apparent that updates to the 1997 guidelines were needed (Denney 2007). As a result, the Petroleum Reserves and Resources Classification, Definitions and Guidelines were updated in 2007 and this document serves as the current standard to define petroleum reserves …show more content…
However, knowledge and techniques gained from Petroleum Geoscience, Reservoir Engineering and Production Engineering will be the most utilised. If the proposed study proves to be successful, it can introduce a new technique that local oil companies can utilise to determine hydrocarbon reserve estimates. Reserves estimation can be considered to be one of the corner stones on which oil and gas exploration and production is based upon. By implementing the use of the Flowing Gas Material Balance method locally, gas reserves can be predicted without having to shut-in the well. This is important because when wells are shut-in hydrocarbons cannot be produced so the application of the FGMB would allow for more productive time in the drilling
The U.S. uses 25% to 30% of the oil produced in the world, yet has less than 3% of known oil reserves,” (Doc C Paragraph 3).This is important because if becoming self-sufficient is impossible than is drilling even worth
With rising gas prices and an increasing reliance on nonrenewable resources, finding a reliable source for extracting and transporting oil has become an issue. In 2010, the Keystone Pipeline project was proposed and commissioned by TransCanada. Essentially, this is a pipeline that transports oil sands bitumen across the Canada-US border and into several different reserves in the States. An additional extension to the Keystone Pipeline, the Keystone XL Pipeline, has also been proposed. Several issues arise when considering the consequences of this new proposal, including the potential for oil spills and habitat damage.
⦁ The map of the Marcellus Shale. ⦁ To penetrate more fracture the use horizontal drilling. Doing so they are capable of drilling millions of cubic feet of gas. ⦁ Issues in the environment
“If we do nothing, it doesn't matter how we feel. And that’s exactly what oil companies are banking on: out of sight, out of mind” (Hart, 24). In his article, 50 Miles Out, Brandt Hart explains the controversy surrounding offshore oil drilling along the east coast. This argument on whether to end or continue drilling started when new oil and gas leasing programs were made for 2017-2022, which included plans for oil and gas “exploration and development” in federal waters (Hart. 24). This plan also includes more oil drilling along American coasts, more specifically the Gulf of Mexico and east coast of the U.S.
The president has made statements to invade Iraq since 2002.Stating that "Iraq continues to flaunt its hostility toward America and to support terror," and even adding that “states like these, and their terrorist allies, constitute an axis of evil, arming to threaten the peace of the world. By seeking weapons of mass destruction, these regimes pose a grave and growing danger.” is Bush during his speech to invade Iraq. Saddam Hussein -was president of Iraq from 1979 to 2003. In his time in office Saddam suppressed the groups that opposed him.
However, the U.S. Department of State argues that the crude oils that are going to be delivered by the Keystone XL pipeline is essentially the same in make up as the ones being supplied to America’s Gulf Coast refineries right now. It also mentions about then Secretary of State Hillary Clinton’s argument that either way, the U.S. will depend on “dirty oil from the Gulf or dirty oil from Canada ….” until the discovery of cleaner technologies becomes possible (Keystone 295). Furthermore, it is important to note that
Although there has been a delay in oil and gas production in recent years, continuous state is an important substance in the US petrochemical industry. Of the US $ 747 billion in domestic refined oil production, US $ 71 billion (9.5% of all domestic production) is attributed to coastal
In Document B it says that jobs would be created, but at the same time it would be too expensive. Document B also says “If oil is discovered, less than 2,000 acres of the 1.5 million acres of the Coastal Plain would be affected” this says that it would destroy people's homes. There is no reason to try to solve a problem, when you’re going to create another. Anything can go wrong if you drill for oil.
The main way that oil and natural gas reserves are acquired are through the means of Fracking. Also known as hydrofracking, this method utilizes a drill that drills down thousands of feet underground, which is then flushed with millions of gallons of water along with additive chemicals at high pressures to break the rocks sheltering the reserves. This method of attainment is quite risky as it comes with many unfavorable consequences that are quite unbeneficial. Like fossil fuel plants, fracking also releases greenhouse gasses like methane(Potential Health and Environmental Effects of Hydrofracking in the Williston Basin, Montana), which is worse than carbon dioxide and causes air pollution. Alongside that, pollutants like Benzene and Xylene also leak out during the fracking process, which is known to cause serious health conditions and even death in some cases due to the long exposure to the pollutants(Potential Health and
You may ask what does the word fracking mean? The United States has many opinions on this hot topic and no one really knows the right answer for it all. The method of Natural Gas Drilling consists of a type of horizontal drilling and hydraulic fracturing, known as fracking. This process peals fissures in underground shale, rock figures by implanting a high pressurized mix of chemicals, fluids and proppants. This causes the fossil fuel to travel to the production well.
With the increased scale of fracking in Texas, one might wonder if the oil boom is affecting our water supply. The value of water in Texas is deeply cherished considering Texas’s dry climate and long-standing droughts. One may even wonder if Texas is valuing its water as much as it is its oil. As research furthers, we can begin to weigh the positive and negative effects of oil fracking. By providing overwhelming data on oil fracking
1. Introduction In 2010, the Deepwater Horizon oil platform spit nearly five million barrels of oil into the Gulf of Mexico, making it the largest oil spill in history. The 1989 oil spill surpassed Exxon Valdez's oil spill in 1989 as the largest oil spill ever seen in US-controlled waters and the Ixtoc I oil spill of 1979 as the largest oil spill in the Gulf of Mexico. On April 20, 2010, Deepwater Horizon, an ultra-deepwater offshore rig, exploded in the Gulf of Mexico about 41 miles off the coast of Louisiana, killing 11 riggers and injuring 17 others.
This graph shown below shows the oils production in 2015-2019 the production oil is reduced and by 2035-2050 the oil produced barrel per year is reduced from 60 billion barrels years to 10 billion barrels be year in
Exxon exercises unique geoscience capabilities and understanding of the global hydrocarbon endowment to identify and prioritize all quality resources in a cost-effective manner. Exxon’s strategy is a cost leadership strategy in the upstream segment by outperforming the competition—creating a comparable value at low-cost—using core competencies: industry-leading technology and capabilities, disciplined approach to investing and cost management, and operations
2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage
