Question

BlackTom AI · Accepted Answer

The prompt asks for a term describing the process of using a mixture of water, sand, and chemicals under high pressure to free tightly held oil and natural gas.
First, consider what the described technique does: it injects a fluid at high pressure to create or enlarge fractures in rock, allowing trapped hydrocarbons to flow more freely toward production wells.
A common technical term for this process is hydraulic fracturing. The addition of sand ( proppant ) helps keep the created fractures open, while the chemicals serve various roles such as reducing fluid friction or preventing microbial growth.
Some students might confuse this with other terms like acidizing or steam injection, but those either use different mechanisms or fluids and aim at different objectives; acidizing uses acids to dissolve rock minerals, whereas steam or thermal methods apply heat rather than fracturing rocks.
Given the wording in the question, hydraulic fracturing (fracking) is the standard descriptor for this high-pressure rock fracturing technique used to enhance hydrocarbon extraction.
Note: the options for this item are not provided in the data, so a direct option-by-option critique isn’t possible here; the explanation above aligns with the widely accepted definition of the process.
