TRUE or FALSE? The increase of the ratio of viscosity of water to the viscosity of oil will increase the fractional flow of water in water flooding.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Increasing the ratio of viscosity of water to the viscosity of oil will actually decrease the fractional flow of water in water flooding. This is because a higher viscosity ratio means that the water is more viscous compared to the oil, making it less likely to flow through the reservoir rocks. As a result, the flow of water during water flooding will be hindered, leading to a decrease in the fractional flow of water.Rate this question:

TRUE or FALSE? in increase of capillary pressure will increase the effect of water coning.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
An increase in capillary pressure refers to an increase in the pressure within the small capillaries in a reservoir. Water coning occurs when the pressure of the reservoir is not sufficient to hold back the water, causing it to rise towards the production well. Therefore, if the capillary pressure increases, it means that the pressure holding back the water is also increasing, which will result in a greater effect of water coning. Hence, the statement "an increase in capillary pressure will increase the effect of water coning" is true.Rate this question:

For Bingham plastic drilling fluid, what is the ratio of shear stress to shear rate if a value of yield stress is zero?
Correct Answer
Plastic viscosityExplanation
If the value of yield stress is zero, it means that the drilling fluid does not require any minimum amount of shear stress to start flowing. In this case, the ratio of shear stress to shear rate is solely determined by the plastic viscosity of the fluid. Plastic viscosity represents the resistance of the fluid to flow under shear stress, and is calculated by dividing the shear stress by the shear rate. Therefore, in the given scenario, the ratio of shear stress to shear rate is equal to the plastic viscosity.Rate this question:

List 2 rock failure mechanism involved in creation of the stimulated reservoir volume in shale reservoirs?
Correct Answer
Shear, TensileExplanation
In shale reservoirs, the creation of the stimulated reservoir volume involves two rock failure mechanisms: shear and tensile. Shear failure occurs when the rocks slide or deform along a plane, causing fractures and creating pathways for fluid flow. Tensile failure, on the other hand, happens when rocks break apart due to stretching or pulling forces, resulting in the formation of new fractures. Both shear and tensile failures contribute to the creation of the stimulated reservoir volume, allowing for improved extraction of oil or gas from shale reservoirs.Rate this question:
