What are the risks in the Oil and Gas industry?

The risk of Drilling in the oil and gas industry Working on a drilling platform far from shore is often dull and routine until something goes wrong. Being isolated at sea during a blowout is a horrific scenario, add fire and you have the disaster witnessed on Deepwater Horizon. Even without fire, a seafloor leak of gas can destabilize the rig as the buoyant properties of the water changes. When wells blowout on land the crew and support personnel can evacuate to a prescribed location to take stock of the situation. Emergency responders are able to rally quickly to a land-based emergency. While land blowouts can still be life-threatening the dangers at sea are multiplied. Many old rig-hands lost fingers and toes either throwing a chain around the pipe while making a connection, mashing digits while racking pipe, engaging tongs, slips, and falls. Common injuries occur just because of bad body position. Fire from leaks, faulty equipment, and smoking has claimed its share of workers. The size and weight of materials needed to drill wells cannot be imagined by people who have never witnessed a well being drilled. What is apparent is that even with strict safety guidelines, a human[…]

interview tips for oil and gas company jobs

Some people wanted to know what kind of technical questions that oil & gas companies might ask during an interview for a process engineering role at a refinery. Here some information from the experts: 1. What do you know about our process? 2. What do you know about our refinery? 3. Why should we hire you? 4. A certain supermajor might ask how a fin fan heat exchanger works and what sort of things could decrease efficiency. Or to draw and describe a distillation column and internals. Know unit op basics: key operation variables, what makes them go bad and how to fix it at a basic level. This helps to know the keywords. 5. Be able to draw PFD and talk about your problem-solving approach. 6. They will certainly test you on typical process engineering fundamentals, but not necessarily topics you would have learned at university. Be prepared to explain your thought process (and maybe even calculate) on questions relating to: Pump sizing, NPSH, cavitation Pressure drop in pipe flow (Bernoulli) Heat exchanger design and selection Ideal gas calculations Vessel inerting/purging method and calculations and of course, distillation operation and improvement They may also get you to present the[…]

Fluid mechanic application in oil and gas industry

What is fluid mechanic? In the oil and gas industry, we are dealing with fluid mechanic problems every day. What is fluid? What is the nature and character of the fluid? To solve this problem we need to understand fluid mechanic basic. Mechanics is physics that deals with stationary objects and moves in the influence of forces. 1) Branches of mechanics that deal with stationary objects are called statics, and 2) The branch of mechanics that deals with moving objects are called dynamics Fluid mechanics is the science that deals with the nature of the fluid in a state of silence (fluid statics) or fluid in a moving state (fluid dynamics), and the interaction of the fluid with solids or other fluids at the surface of its boundary. Fluid mechanics is often also called fluid dynamics by looking at silent fluid as a special case of fluid moving at zero speed. Fluid statics deal with silent fluid problems. Example: fluid in a glass, fluid in a pressure vessel, fluid in a reservoir, etc. Silent fluid is in equilibrium (the resultant force acting on it is equal to zero). In a silent fluid (fluid does not flow) there is no shear[…]

API & ASME – Code and standard used in oil and gas industry

American Petroleum Institute (API) The American Petroleum Institute (API) is an associated organization of various industries in the United States engaged in petroleum and natural gas. API currently has distributed more than 200,000 technical pieces standards to all over the world. The purpose of these standards is to help its users in an effort to increase efficiency and savings in the operation of their businesses, by still referring to legislation, safeguarding the safety and health of the community, and not forgetting to preserve the environment. In addition to producing standards, codes and implementation guidelines relating to piping, tanks, vessels, and equipment in the oil and gas industry, the APL also provides instructions on maintenance matters, inspections of equipment that is working, evaluating components is experiencing a decline in ability, also referred to as “fitness-for-service” or “for-purpose fitness.” Although it is recognized that most documents produced by the API are for consumption in the oil and natural gas industries, many standards Relevant API and can be used for the petrochemical industry in general. Some API Standards that are often used in Engineering are as follows: 5L  Specification for Line Pipe 510 Fired Heater Tubes 520 Sizing, Selection, and Installation of Pressure-Relieving[…]
