introduction to Oil and Gas Facilities

Oil and Gas well Most people argue that oil and gas wells produce crude oil and pure gas. Whereas actual gas wells produce a fluid whose content is a mixture of hydrocarbon gas, oil, water, large quantities of salt; other gases such as carbon dioxide (CO2) or hydrogen sulfide (H2S) that highly toxic and lethal. Oil and gas wells also produce solids, such as sand from underground / reservoirs, dirt, and corrosion products from tubing. In the Upstream oil and gas business, oil and gas processing companies work to separate the fluids with solids, remove dirt and other unused substances to produce crude oil or gas ready for sale. Ready-made crude oil has limits to the maximum limits of water, salt, and other impurities. Oil companies such as Chevron or Exxon built field oil facilities used to process or separate produced fluids into crude oil and gas. Oilfield facilities differ[…]

ultrasonic testing, the most powerful and easiest inspection method in oil and gas industry

Ultrasonic testing One of the most common and easiest inspection methods in the oil and gas industry is Ultrasonic testing or commonly known as UT. UT is a non-destructive testing technique based on the propagation of ultrasonic waves in the material tested. Usually, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, is transmitted into materials like carbon steel to detect material thickness or to find internal defect inside the material. UT equipment consists of several parts that have different functions such as Pulser / receiver, transducer, and monitor screen. Pulser / receiver is an electronic equipment that can produce high-voltage electrical pulses. the transducer produces high-frequency ultrasonic energy. The ultrasonic energy is discharged and dispersed through or entered into the test material in a waveform. If there is a defect or discontinuity (such as crack) on the wave path, then some energy will be reflected back from[…]

best practice to develop career in oil and gas company

Oil and Gas company The oil and gas company has always been an idol for job seekers due to large revenues and large industrial scope. But the oil and gas industry sometimes faded due to unfavorable fluctuations in world oil prices. how to build a career in the oil and gas industry? We do not need to worry about with the oil and gas sector at this time. because all the business there is a cycle. We believe energy will not be separated from the growth of the country, and the largest source is still in oil and gas. for example, there are companies in this industry for 125 years, continues to grow through the acquisition and organic. What is the choice of profession in this industry? oil and gas sector consists of various businesses. The chain is long, from exploration, exploitation, extraction, and others. the companies involved are also[…]

basic material knowledge for Mechanical engineer : Carbon Steel

Carbon steel Callister and Rethwisch (2010) classified iron alloys based on carbon composition into 3 groups: iron with carbon content <0.008%, steel with a carbon content of 0.008% C to 2.14% C and cast iron with carbon content> 2.14%. The steels were subdivided into 3 groups: low carbon steel, medium carbon steel, and high carbon steel. low carbon steel Low carbon steels generally contain less than about 0.25% C and are unresponsive to heat treatment intended to form martensite. Reinforcement can be achieved by cold work. The microstructure consists of ferrite and pearlite constituents so that the alloy is relatively soft and weak but has excellent ductility and toughness. Low carbon steels are easy to work with (machinable) machines, easily welded (weldable) and least expensive to produce. medium carbon steel Medium carbon steels have a carbon concentration between 0.25 to 0.60%. This alloy can be heated by austenitizing, quenching, and[…]
