Inhibition in drilling fluids?
Inhibited drilling fluids are mainly used to prevent shale swelling during drilling operations. These drilling muds can be either oil-based or water-based. The most effective way to prevent shale swelling is using oil-based-mud (OBM), but water based muds (WBM) can also be used if such inhibitors like KCl, etc are added to the drilling fluid.
Fluid flow in an annular space?
Fluid flow in an annular space occurs during a drilling operation of the gas and oil well. The correct prediction of the flow lies in the drilling mud in the annular space between the well.
What does Baker Hughes do?
Baker Hughes is an oilfield service company. They provide the oil and gas industry with products and services for drilling, formation evaluation, completion, production, and reservoir consulting.
How do you get crude oil?
Crude oil is organic remains of plants and animals Buried long ago. The organic material over a long period of time changes to different length of hydrocarbons. Crude oil is unrefined petroleum. The way to get crude oil through drilling. The exploration and finally the drilling process are complex and require investments and skill.
Petroleum Engineer?
Petroleum engineering is the engineering specialty that is focused on locating and extracting sources of petroleum. These engineers often work with specialists such as geologists and hydrologists to determine the best, most cost effective method to remove petroleum sources from the earth. The chief responsibility of a petroleum engineer is to select and supervise the method by which petroleum sources are to be extracted. However, the job is not nearly that simple, there are several factors that impact the engineer’s decisions. The first factor that petroleum engineers consider when drilling is the depth at which the reservoir is located as different drilling methods are to be used at varying depths. From there, the engineer must test the reservoir to determine its size and level of connectivity. In some cases it is possible to remove petroleum from multiple reservoirs through complex drilling and a process known as fracturing. The last, and often most important, decision made by a petroleum engineers involves the pressure and other environmental factors that allow petroleum to naturally flow to the surface of a well. Petroleum engineers have employed a variety of methods to remove as much petroleum as possible from a well; examples would be injecting steam and water into the reservoir. The minimum requirements to become a Petroleum Engineer are to earn a bachelor’s degree in petroleum engineering; however, it is very possible to cross over from another engineering specialty such as chemical or mechanical engineering. It is a very good idea for students interested in petroleum engineering to secure an internship during college to gain highly valuable work experience. Graduate degrees are necessary for many research and development positions. The employment opportunities in petroleum engineering are expected to be very good. There is to be an 18% growth over the next decade according to www.bls.gov ; in addition, there are too few graduates with degrees in petroleum engineering to fill the positions. Petroleum engineers are the most highly paid of the engineering specialties; starting salaries for a petroleum engineer are typically around $83,000, one of the highest for any bachelor’s level program. On average, workers in the field earn from $100,000 to $110,000.
Which are the objectives of the drilling mud?
Oil base mud
What is the function swivel in drilling rig?
the swivel has three functions: -to conduct drilling mud -to cease the rotary movement -to sustain
Is low tox drilling mud oil or water based?
Low tox drilling mud is water based.
How much does drilling mud weigh?
The weight of drilling mud can vary depending on the type and density. However, typical drilling mud weights range from 8.6 to 19 pounds per gallon (1.03 to 2.27 kg/L).
Is drilling mud a chemical?
Yes, it is. Drilling fluids, the circulating fluid for drilling operations, is a mixture of the fluid, the solid and chemical agents. It is usually known as the "mud" or the "blood of drilling" deriving from its distinctive significance.
How you make spud mud in drilling?
Depends on what mud system you use.
Does offshore oil drilling harm wildlife?
Yes, minorly, it is drilling mud.
Function of circulating mud system?
Drilling fluids circulating mud system is an important and obligatory constituent part in the modern drilling equipment, it can keep the mud normal circle and stable performance in drilling process, ensure drilling works on the premise of safety, environmental protection and high efficiency.
Various drilling mud have the same apparent viscosity at 1022sec-1 but the effective viscosity at other shear rates may vary widely Explain?
Drilling mud is a nonnewtonian fluid. It's a thixotropic fluid and it's apparent viscosity is a function of shear rate and time so at various shear rate and times you will have various viscosities. The molecular structure of these fluids breaks during tention.For further informations you can refer to rheology or fluid mechanics books.
What is mud conditioning?
Mud conditioning is a term used in well drilling operations. It is simply, the treatment and control of drilling mud to ensure proper gel strength, viscosity, density etc.
What are the Drilling mud ratios for sand gravel mix?
Typically, the drilling mud ratio for a sand gravel mix is around 1:1 to 1:2, meaning one part drilling mud to one or two parts sand and gravel. This ratio may vary depending on the specific drilling conditions, equipment used, and desired drilling outcomes. It is important to consult with a drilling mud engineer or supplier to determine the best ratio for your particular situation.
