Hillard Huntington et al.2013 Fracking was developed to get the remnants of oil contained in production wells‚ especially in old oil wells. This process is effective to increase the number of production wells. Fracking is highly controversial in many countries such as‚ USA‚ German‚ and UK. Some people say that fracking can advocate the economic benefits of more broadly accessible hydrocarbons.

natural gas or oil. How the process works: The process includes steps to protect water supplies. To ensure that neither the fluid that will eventually be pumped through the well‚ nor the oil or gas that will eventually be collected‚ enters the water supply‚ steel surface or intermediate casings are inserted into the well to depths of between 1‚000 and 4‚000 feet. The space between these casing “strings” and the drilled hole (wellbore)‚ called the annulus‚ is filled with cement. Once the cement

Assalamualaikum and a very good evening I wished to my beloved lecturer‚ Madam Shima and to all my fellow mates. My name is (name)‚ I’m from PE department‚ 2nd year 1st semester. I have been studying Petroleum Engineering for almost 2 years now and have been exposed with many things regarding the Petroleum Engineering. So‚ I hope you guys can listen to what I’m going to present after this. (Slide 2) I believed that all of you‚ an engineer-to-be‚ will someday works with the oil and gas industry and

Because there was no surface or groundwater pollution off the plant property‚ the plant manager decided to do nothing. Jesse thought that somewhere under the plant there still sits this plume‚ although the last tests from the sampling wells showed that the concentration of the chemical in the groundwater within 400 feet of the surface was essentially zero. The wells were capped‚ and

drilling mud. All drilling fluids‚ especially drilling mud‚ can have a wide range of chemical and physical properties. These properties are specifically designed for drilling conditions and the special problems that must be handled in drilling a well. Purpose of Drilling Fluids 1. Cooling and lubrication. As the bit drills into the rock formation‚ the friction caused by the rotating bit against the rock generate heat. The heat is dissipated by the circulating drilling fluid.
