Drilling rig

to be used for the drilling process. This process is already contributing to the greenhouse gas footprint. Once a drilling rig is set up, a surface hole is then drilled to a depth past the underground aquifer. Steel casing is run into the wellbore and the cement is pumped down to hold it into place. In theory, this is done to protect the aquifer from migrating gas at the completion of the well. A process to be done a few more times with smaller diameter steel casing as drilling continues through…

hand. There are multiple types of gold mining: hard rock mining, hydraulic mining, and placer mining. Hard rock mining is mining hundred of feet underground in tunnels inside of mountains. Hard rock miners use tunnel boring machines, crusher, and drilling rig. Tunnel boring machine is a machine that consists of a bunch of little metal teeth that eat away at the rock. Crusher is a machine that crushes rocks into small pieces…

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 can be translated to the cost of almost 2 rig-years every year. An analysis of the stuck pipe incidents revealed that…

Deepwater Horizon The Deepwater Horizon offshore drilling unit and Macondo Well explosion on April 21, 2010 was only the latest in a line of recurring issues and near misses in the high risk production of oil and gas drilling platforms. Most of these near misses and issues can be traced back to a common set of characteristics relating to system defects, safety violations that went ignored, human factors and a lack of organizational integrity (Kurtz, 2013). Comparisons from experts in two…

range from gasoline, diesel or some sort of petrochemical. 2. Extraction: When looking at all four areas mentioned, most of the processes used for the extraction of the oil is comprised of drilling, pumping and fracking (excluding Gulf of Mexico). The Gulf of Mexico has more than 4,000 active platforms drilling with the majority of them in waters less than…

These actions on BP’s behalf demonstrated how they were taking responsibility for their actions tangibly to mitigate the damages (Wickman, 2014). However, a shift in rhetoric was emerging as blame was being placed on Transocean who they lease the rig from, and Halliburton who was responsible for the cementing (O'Connor, 2011). Even with Mr. Hayward’s responsiveness to rectifying the issues caused by the spillage, the Gulf Coast residences were becoming increasingly impatient with BP’s…

requires a lot of work and precision, petroleum engineers often choose different fields to specialize in. These fields range from exploration, drilling to petroleum accounting, economy and sales. There are different paths to becoming a petroleum engineer: One can start right after high school with a simple GED, be recruited as a simple roughneck on a rig, where most people gain most of their experience and work their way up to very high field positions such as supervisor or manager. Another way…

The first trial which was closing the blowout preventer valves with underwater vehicles but it failed. Then, the second method which was doming over the largest leak part with containment and third method which restrict the flow of oil by pumping drilling fluid also failed. After that, BP succeed to restrict the flow of oil by putting a “Top Hat Number 10” which fitted better at the wellhead and then sealed part of flow channel permanently by pumping cement from the top and the well has been…

In the Seasons of Life and Land, author Jimmy Carter argues that our arctic and its wildlife refuge are in danger and needs to be preserved. He clearly states the current situation and persuades the readers against such actions as to installing oil rigs for it may disrupt the caribou and their way of life as well as many other species of animals. Carter had the privilege to first hand experience the Arctic National Wildlife Refuge and he, himself was saddened at the thought of what might happen…

managers at a time starting with the lowest performing rigs. The goal is to train all current managers within 3 years and to make the training process an ongoing requirement for future management positions. The purpose of targeting managers to receive leadership training is because they have the most people-to-people contact. Managers have the responsibility of communicating between high level administrators, other managers, and lower level rig workers. We believes quality trained managers will…
