Poor Boy Degasser or Mud Gas Seperator, located downstream of the choke manifold, is a vertical vessel used to separate any gas from drilling fluid during well control situation. Once the gas has been separated, it can pass through the vent line in the derrick. Alternatively, as long as it’s a safe distance from the rig, it could even be vented.

With mud’s separators, there are two main types. Also known as a ‘poor-boy’ and a ‘gas buster’, the more common of the two is called an atmospheric mud/gas separator. However, some mud/gas separators are designed to operate at moderate back pressure. Although these will mostly operate under 100 psig, it’s possible to come across those that work at the atmospheric gas vent line pressure plus the vent line friction drop. The simple diagram of poor boy degasser is show in figure 2.

A degasser is equipment used to remove entrained gas in drilling fluid so it prevent or minimize reduction of hydrostatic pressure due to gas cut mud. When drilling mud passing over the shale shakers while drilling, gas will normally be released. However, the wellbore could receive additional volumes of gas and these need to be removed from the mud. If not removed from the circulating system properly, recirculation of mud containing gas will reduce the well’s hydrostatic head. With a degasser, this can eliminate or minimize loss of hydrostatic pressure.

Mounted over the active pit, degassers are essentially a one-stage liquid/gas separator. With a maximum lift to the inlet of around ten feet, mud vacates the submerged pipework in the mud pit and enters the degasser. From here, a three hp electric motor will power a vacuum pump and this should be mounted atop the degasser itself. By the pump, the vacuum is then applied to the vapor space.
Ultimately, the range applied by the vacuum will depend on the density of the mud passing through. In most cases, it will offer between 2-5 pounds per square inch (between 8 and 15 inches of mercury). In terms of extracting gas from mud flows, 900 gallons per minute is likely to be the maximum rate. Continue reading
Writing the resume for newly graduated student is quite different from the experienced personnel because they don’t have working experience to add in the resume. This is not the problem because this section is dedicated for someone who just graduates from the collage.
You may start with your personnel information as address, telephone number, email, etc. Then you need to add the objective why you are applying for this position. Your objective should be precise because many people write so long objective but employers don’t understand what the new students want.
Next is the middle part of your resume which should be easy to read. The middle description should include your educational background, your experiences when you are in the school, your technical knowledge, your computer skill, etc. The most important of this section is your educational background. When you mention your education, you need to start with your recent degree including your degree with date, university name and the grade.
Additionally, if you have an internship experience, this information should be included in your resume too because many employers will seek the people who has the same experience for the position. You should mention the joining date of the position that you are working for and the company name. Continue reading
