Natural gas

Nuclear energy has certainly come a long way since its introduction to the public in 1945. The world stood in shock at the revelation of the destructive capabilities of the two first nuclear weapons “Fat Man” and “Little Boy.” The actual development of nuclear energy began in the 20th century following the discovery of the elements uranium and plutonium. When the bombs were detonated these elements produced enormous sums of energy in the form of both heat and radiation; these hazardous…

Since the creation of electricity, people have searched for the most efficient source of energy. There are many common sources of energy, and they all have their own flaws. Many of the common energy sources are nonrenewable resources; therefore, they are not a logical source of energy for the future. Some of the energy creating processes can be very dangerous to humans and the environment. Many of these sources are not economical either. To be considered efficient, an energy source must be…

Petrobras is a Brazilian oil company that was created by the Brazilian government in 1953. For the first decade Petrobras struggled to be successful despite being given a constitutional monopoly by the Brazilian government. Brazil did not have any oil reserves or the knowledge in oil exploration, and the goal for Petrobras was to become a world class oil producer. Petrobras began to see success in the 1980s when they developed deep water and ultra-deep oil production. This new technology…

Response: One of the major operation challenges in the E&P industries are stuck pipe incidents which usually lead to a considerable amount of lost time and associated costs. The increases in drilling activity, drilling in depleted and higher risk reservoirs leads to an increased risk of stuck pipe. As we can observe in this case for this NOC, the greatest impact is when the drilling performance is Non-Productive Time (NPT). We know that around 25% of the NPT is regarded to stuck pipe and this…

Geothermal energy is one of the most recommended sources of renewable energy for electricity. It is more useful especially in areas where there is a lot of volcanic activity. Since geothermal energy is extracted from deep within the earth’s surface, it is safe, clean, reliable, and environment friendly. However, despite all these advantages, this type of energy suffers from its disadvantages as explained below. Disadvantages of geothermal energy Location It’s not easy to find the most…
