question 55

Multiple Choice

The figure below shows close-up views of two sand deposits that have differing degrees of cementation.Which explanation about how increased cementation of the clasts would affect the ability of oil to flow to a well does NOT make sense?

• A) It would slow down the flow of oil to the well because the passages are on average less connected.
• B) It would slow down the flow of oil to the well because the passages are on average narrower.
• C) It would have no effect if there are sufficient, interconnected fractures in the rock (though not visible in the figures).
• D) It would speed up the flow of oil to the well because flow through narrower passages will generate more friction and thereby heat the oil and decrease its viscosity.
