What is the common drilling fluid type which is widely used in drilling?
a) Compressed air
b) Oil-based mud
c) Foam-based mud
d) Water-based mud
🕹Refining Of CRUDE- is Boiling Oil👇🏼
A large part of refining involves separating the different fractions of crude oil and other intermediate streams. While water boils at a single temperature, crude oil boils over a wide range of temperatures. By controlling the temperature using very tall distillation columns, different fractions of the crude oil can be separated.
At the top of the column, fuel gas and liquefied petroleum gas (or LPG) is produced. A little lower down the column, gasoline (or, more precisely, one of the blending stocks for gasoline called naphtha) is withdrawn. Still lower down the column, jet fuel and diesel fuel are produced.
DIRECTION, MOTION & ENVIRONMENTAL FORCES at OFFSHORE
Wind force is given by
Fw = 0.00338 (Vw)^2 *Ch *Cs* A
where Fw = wind force, lbf,
VA = wind velocity, knots,
Cs = shape coefficient,
Ch - height coefficient, and
A = projected area of all exposed surfaces, sq. ft.
Current force is given by
Fc=gc*(Vc )^2*Cs*A,
where Fc = current drag force, lbf,
Vc = current velocity, ft/sec,
Cs =drag coefficient same as wind coefficient, and
A = projected area of all exposed surfaces, sq. ft.
__________represents the relative effect of viscous forces and surface tension acting across the interface between two immiscible liquids.
There are known effects of gas on logging tool responses. Which of the following statements is correct?
Which one of the following logging techniques is most suitable to detect a shale layer sandwiched between two sandstone layers?
Unconventional reservoirs are not characterised by _____
Estimate the total theoretical maximum overpressure gradient in lb/feet3 if the specific gravity of is earth crust taken equal to 2.7. Consider porosity of average sedimentary rock equals to 20 %. The specific gravity of saltwater taken to be 1.07.
What will be the effect on permeability when specific surface decreases?
Subsea wells may be installed individually, in a clusters, or on a template where the reservoir fluids from all the wells are channeled to a manifold that is tied back to a host platform.
Template System: A subsea production facility where the wells, connectionsand manifolds are on a common supporting structure or template.
Cluster Well System: A centrally located manifold around which independent satellite wells are clustered. These wells individually connect to theproduction manifold.
Which type of system is shown above ?
Name the flow meter.. Can its reading be affected by changing Temperature. Why?
The torque on a motor shaft follows a sinusoidal pattern with a maximum amplitude of 8,000 ft-lbf. The torque will always be positive through the cycle. Shaft speed is 200 rpm. Calculate the motor horsepower.
